Analog Outputs
The update rate for analog outputs is 250μs; although the output will only change at the update rate defined by the source parameter for the input. The following exceptions apply:
Analog Inputs
The normal sample rate for the analog inputs is 4ms, however this is increased to 250us for analogue inputs 1 and 2 under the following conditions:
Note that Analogue Input 1 Fast Update Active (07.026) and Analogue Input 2 Fast Update Active (07.027) indicate if fast updating is active for each input.

Thermal monitoring is provided within the drive to protect the power stage and the control system from over temperature.
Monitored Temperature 1 (07.004), Monitored Temperature 2 (07.005) and Monitored Temperature 3 (07.006) give an indication of the temperature of three selected monitoring points within the drive power system or control system. The required monitoring points can be selected using Temperature Monitor Select 1 (07.038), Temperature Monitor Select 2 (07.039) and Temperature Monitor Select 3 (07.052) respectively. The default values give two monitoring points in the power system in Monitored Temperature 1 (07.004) and Monitored Temperature 2 (07.005), and control board temperature 1 in Monitored Temperature 3 (07.006).

This is an instantaneous power output with fast update rate that is primarily intended to be used as a power feed-forward for applications with a Regen system front end. The full scale (100.0%) value is equal to a power of 3 x (VM_DC_VOLTAGE[MAX] / 2√2) x Full Scale Current Kc (11.061). This is compatible with the power output provided in Unidrive SP and is directly comptible with Power Input 1 (03.010) (and the other power feed-forward parameters) in Regen mode. The scaling is intended to cover the maximum range of likely power in the drive. For example with a 400V 7.5kW drive the full scale d.c. link voltage is 831V and Kc=38.222A, and so the full scale value of this parameter is 3 x (831 / 2√2) x 38.222 = 33.689kW. For Open-loop, RFC-A and RFC-S modes a positive value of power indicates power flowing from the drive to motor. For Regen mode a positive value of power indicates power flowing from the supply to the regen drive.

Percentage Of Drive Thermal Trip Level (07.036) gives the percentage of the thermal trip level of the temperature monitoring point or thermal model in the drive that is highest. This includes all thermal monitoring points (not just those selected by Monitored Temperature 1 (07.004), Monitored Temperature 2 (07.005) and Monitored Temperature 3 (07.006)), Inverter Temperature (07.034) and Percentage Of d.c. Link Thermal Trip Level (07.035).
Percentage Of d.c. Link Thermal Trip Level (07.035) is used directly to give Percentage Of Drive Thermal Trip Level (07.036), but for all other monitored values which are temperatures this is given by Percentage of thermal trip level = (Temperature - 40oC) / (Trip temperature - 40oC) x 100%
The location of the measurement or the thermal model that is related to this temperature is given in Temperature Nearest To Trip Level (07.037). If Percentage Of Drive Thermal Trip Level (07.036) exceeds 90% Drive Over-temperature Alarm (10.018) is set to one. If Percentage Of Drive Thermal Trip Level (07.036) reaches 100% one of the trips given in the table below is initiated. The trip can be reset when the percentage of thermal trip level fall below 95%.
