Trip 0 (10.020) to Trip 9 (10.029) store the most recent 10 trips that have occurred where Trip Trip 0 (10.020) is the most recent and Trip 9 (10.029) is the oldest. When a new trip occurs it is written to Trip 0 (10.020) and all the other trips move down the log, with oldest being lost.

The date and time when each trip occurs are also stored in the date and time log, i.e. Trip 0 Date (10.041) to Trip 9 Time (10.060). The date and time are taken from Date (06.016) and Time (06.017) (See Date/Time Selector  (06.019)). Some trips have sub-trip numbers which give more detail about the reason for the trip. If a trip has a sub-trip number its value is stored in the sub-trip log, i.e. Trip 0 Sub-trip Number (10.070) to Trip 9 Sub-trip Number (10.079). If the trip does not have a sub-trip number then zero is stored in the sub-trip log.

Trip categories and priorities
Trips are grouped into the categories given in the table below. A trip can only occur when the drive is not tripped, or if it is already tripped and the new trip has a higher priority than the active trip (i.e. lower priority number). Unless otherwise stated a trip cannot be reset until 1.0s after it has been initiated.

Priority Category Trips Comments
1 Internal faults HF01 - HF19 These are fatal problems that cannot be reset. All drive features are inactive after any of these trips occur. If a basic keypad is fitted it will show the trip, but the keypad will not function. These trips are not stored in the trip log.
1 Stored HF trip Stored HF This trip cannot be cleared unless 1299 is entered into Parameter mm.000 (mm.000) and a reset is initiated.
2 Non-resettable trips Trip numbers 218 - 247 and Slot1 HF These trips cannot be reset.
3 Volatile memory failure EEPROM Fail This can only be reset if Parameter mm.000 (mm.000) is set to 1233 or 1244, or if Load Defaults (11.043) is set to a non-zero value
4 Non-volatile media trips Trip numbers 174, 175 and 177 - 188 These trips are priority 5 during power-up
5 Trips with extended reset times

OI ac, OI Brake and Reserved

These trips cannot be reset until 10s after the trip was initiated.
5 Phase loss and d.c. link power circuit protection

Phase Loss and OHt dc bus

The drive will attempt to stop the motor before tripping if a Phase Loss.000 trip occurs unless this feature has been disabled (see Action On Trip Detection (10.037)). The drive will always attempt to stop the motor before tripping if an OHt dc bus occurs.
5 Standard trips All other trips

Trips {HF01} to {HF19} are internal faults that do not have trip numbers. If one of these trips occurs, the main drive processor has detected an irrecoverable error. All drive functions are stopped and the trip message will be displayed on the drive keypad. The error can only be reset by powering the drive down and up again. The table below gives the reasons for internal faults and their corresponding trip

Trip Reason
{HF01} CPU hardware fault during exception processing
{HF02} CPU memory management fault is an exception that occurs because of a memory protection related fault
{HF03} CPU has detected a Bus Fault. A Bus Fault is an exception that occurs because of a memory related fault for an instruction or data memory transaction. This might be from an error detected on a bus in the memory system.
{HF04}

CPU has detected a usage fault:
A Usage Fault is an exception that occurs because of a fault related to instruction execution. This includes:

  • an undefined instruction
  • an illegal unaligned access
  • invalid state on instruction execution
  • an error on exception return.

The following can cause a Usage Fault when the core is configured to report them:

  • an unaligned address on word and half word memory access
  • division by zero.
{HF05} Reserved
{HF06} Reserved
{HF07} Watchdog failure
{HF08} CPU Interrupt crash. Interrupt crash level indicated by subtrip number.
{HF09} Free store overflow
{HF10} Reserved
{HF11}

The HF11 trip indicates that a non-volatile memory comms error has occurred.

Sub-trip

Reason

Recommended action

1

Non-volatile memory comms error.

Hardware fault – contact the supplier of the drive.

2

EEPROM size is incompatible with the user firmware.

After 1min the drive will go to its bootloader. Re-program drive with compatible user firmware using UniMConnect

{HF12}

Stack overflow

Sub-trip

Reason

1

User program or derivative background stack overflow

2

User program or derivative timed stack overflow

3

Main system interrupt stack overflow

4

Main system background stack overflow

{HF13}

Reserved

{HF14}

Reserved

{HF15}

Reserved

{HF16} RTOS error (the background task has returned)
{HF17}

Reserved

{HF18}

The HF18 trip indicates that the internal flash memory has failed when writing option module parameter data. The reason for the trip can be identified by the sub-trip number.

Sub-trip

Reason

1

Option module initialization timed out

2

Programming error while writing menu in flash

3

Erase flash block containing setup menus failed

4

Erase flash block containing application menus failed

5

Incorrect setup menu CRC contained in flash

6

Incorrect application menu CRC contained in flash

{HF19} The HF19 trip indicates that the drive firmware is partially or completed deleted. The drive is now in its bootloader and is waiting for a new image to be downloaded using UniMConnect. Once a new image is downloaded, the drive can run normally.

When the drive is subsequently powered up a Stored HF trip is initiated where the sub-trip number is the number of the HF trip that last occurred. This trip will occur at every power-up until it is reset. The trip can only be reset by first entering 1299 into Parameter mm.000 (mm.000).

Trip descriptions
Trips shown in the table below can be generated either from the drive control system or from the power system. The sub-trip number which is in the form xxyzz is used to identify the source of the trip. The digits xx are 00 for a trip generated by the control system or the number of a power module if generated by the power system. If the drive is not a multi-power module drive then xx will always have a value of 1 the trip is related to the power system. The y digit is used to identify the location of a trip which is generated by a rectifier module connected to a power module. Where the y digit is relevant it will have a value of 1 or more, otherwise it will be 0. The zz digits give the reason for the trip and are defined in each trip description.

A thermal protection system is provided for the braking resistor. If Braking Resistor Rated Power (10.030) is set to zero this protection system is disabled and the Braking Resistor Thermal Accumulator (10.039) is held at zero. If braking resistor thermal protection is required the Braking Resistor Rated Power (10.030)Braking Resistor Thermal Time Constant (10.031) and Braking Resistor Resistance (10.061) should be set up with the braking resistor parameters. The thermal time constant of the resistor can be calculated from the single pulse energy rating (E) and continuous power rating (P) of the resistor.

Braking Resistor Thermal Time Constant (10.031) = τ = E / P

The braking resistor is protected with a single time constant model as shown below.

The drive monitors the power flowing into the braking resistor and updates the Braking Resistor Thermal Accumulator (10.039). If bit 1 of Action On Trip Detection (10.037) = 0 and the accumulator reaches 100% an Brake R Too Hot trip is initiated. If bit 1 of Action On Trip Detection (10.037) = 1 and the accumulator reaches 100% the braking IGBT is disabled until the accumulator falls below 95.0%.

If Number Of Auto-reset Attempts  (10.034) = 0 then no auto-reset attempts are made. Any other value will cause the drive to automatically reset following a trip for the number of times programmed after a delay defined by Auto-reset Delay (10.035) subject to the minimum reset time allowed for the type of trip. Note that for some trips the minimum is 10s. The auto-reset count is only incremented when the trip is the same as the previous trip otherwise it is reset to 0. When the auto-reset count reaches the programmed value, any further trip of the same value will not cause an auto-reset. If there has been no trip for 5 minutes then the auto-reset count is cleared. Auto reset will not occur after any trips with priority levels 1, 2 or 3 as defined in Section 4. When a manual reset occurs the auto-reset counter is reset to zero.

If Number Of Auto-reset Attempts  (10.034) = 6 the auto-reset counter is held at zero, and so there is no limit on the number of auto-reset attempts.

The bits in Action On Trip Detection (10.037) are defined as follows:

Bit 0: Stop on defined non-important trips
If bit 0 is set to one the drive will attempt to stop before tripping if any of the following trip conditions are detected: I/O Overload, Keypad Mode, Motor Too Hot, EEPROM Fail or user 24V failure.

Bit 1: Disable braking resistor overload detection
See Braking Resistor Rated Power (10.030).

Bit 2: Disable phase loss stop
Normally the drive will stop when the input phase loss condition is detected. If this bit is set to 1 the drive will continue to run and will only trip when the drive is brought to a stop by the user.

Bit 3: Disable braking resistor temperature monitoring
If hardware based braking resistor thermal monitoring is provided this can be disabled by setting this bit to one.

Bit 4: Disable parameter freeze on trip
If this bit is 0 then the parameters listed below are frozen on trip until the trip is cleared. If this bit is 1 then this feature is disabled.

When a value other than zero is written to the User Trip (10.038) the actions described in the following table are performed. The drive immediately writes the value back to zero. If the value is not included in the table, then the action is the same as if the trip with the same number (with sub-trip zero) occurred provided the drive is not already tripped.

Because the drive clears immediately this parameter to 0, the value must be written via serial communication or user program if supported.

The bits in Trip Reset Source (10.102) correspond to each of the trips in the trip log (i.e. bit 0 corresponds to trip 0, bit 1 corresponds to trip 1, etc.). When a trip occurs, bit 0 is set to one and the other bits corresponding to the trips already in the trip log are shifted left one bit. If the trip is reset then bit 0 is set back to zero, otherwise if a higher priority trip occurs bit 0 is shifted left by one bit. The result is that each of the bits in Trip Reset Source (10.102) show whether trips in the trip log were reset or moved up the trip log by a higher priority trip.

When a trip occurs the time in milliseconds since the drive powered up is stored in Trip Time Identifier (10.103). The time rolls-over when it reaches 232 - 1, but if the time is 0 a value of 1 is written. Trip Time Identifier (10.103) can be used to determine when a new trip has occurred as the value will change (unless there were exactly 232ms between trips) and will be non-zero.

If there is no alarm then Active Alarm (10.104) = 0. If one alarm is active then Active Alarm (10.104) shows the value of the alarm. If more than one alarm is active then Active Alarm (10.104) shows the active alarm with the lowest value. The strings from this parameter are also used by the basic keypad to provide the status display text except for option slot warnings where the option module may supply the string.
