Digital I/O Interface
The normal sample rate for the digital I/O system is 2ms, however it is possible to obtain a faster update rate for some parameters with certain inputs as described below. (Note that the keypad buttons are always updated at the background rate and cannot be used for fast updating.)
Direction, read and write register parameters
Digital I/O Output Enable Register 1 (08.071), Digital I/O Input Register 1 (08.072) and Digital I/O Output Register 1 (08.073) provide direct access to read/control the digital I/O that is integral to the drive.
Limit Switches
If digital inputs 4 or 5 are routed to either the Forward Limit Switch (06.035) or Reverse Limit Switch (06.036) in RFC-A or RFC-S modes the update rate is 250us.
Parameters
The same parameter structure is used for every digital I/O except for the Safe Torque Off inputs which are dedicated inputs that do not include routing as shown in the diagram below.
The table below gives the digital I/O parameter structure.

The Digtial I/O State parameter shows the state of digital I/O on the drive. All I/O except Digital Input 11 (Keypad Run Button), Digital Input 12 (Keypad Auxiliary Button), Digital Input 13 (24V Supply Input) and Digital Input 14 (Keypad Stop Button) use IEC61131-2 logic levels. As default the inputs use positive logic, and so the state parameter is 0 if the digital I/O is low or 1 if the digital I/O is high. Input Logic Polarity (08.029) can be set to zero to change the logic for Digital I/O1-6 to negative logic, so that the state parameter is 0 if the digital I/O is high or 1 if the digital I/O is low. The state parameter represents the digital I/O state whether it is an input or an output. If the digital I/O is configured as an output to be controlled using the Digital I/O Output Register 1 (08.073) then the state parameter will still show the state of the output even though the route source is zero and the invert parameter has no effect.
Digital Input 11 (Keypad Run Button), Digital Input 12 (Keypad Auxiliary Button) and Digital Input 14 (Keypad Stop Button) represent the state of the Run, Auxiliary and Stop buttons on any keypad fitted to the drive; the input state is determined by ORing the state of the button on each keypad connected to the drive, if the button is pressed the state parameter is one otherwise it is zero. If a keypad is not fitted the state parameters are zero.
Digital Input 13 (24V Supply Input) is an external 24V supply input that is monitored and can be used as a 24V digital input if an external 24V supply is not required. The state parameter is low for the voltage range from 0V to 17V and high for the voltage range above 18V. As the input is a power supply it will consume significant current if the level is taken above 24V when the drive is running from its internal power supply, or at any voltage level if this input is the only power supply to the drive.
Digital Input 09 (STO input 1) and Digital Input 10 (STO input 2) correspond to two safe torque off channels within the drive. Both channels must be in the high state for the drive to be enabled. The state parameters are 0 if the digital input is low, or 1 if the digital input is high. If option slot 3 does not contain an option module providing safety functions then both safe torque off channels are connected to their state parameters and the safe torque off input can enable/disable the drive. If an option module providing safety functions is fitted in option slot 3 then the option module can disable the drive by breaking the path of either one or both safe torque off channels. See Menu 6 for details of the drive enable system.

The Digital I/O Input Register 1 (08.072) is always active and shows the value in the Digital I/O State parameter for all digital I/O configured as inputs. Bits in the Digital I/O Output Register 1 (08.073) can be used to control the digital I/O directly. The bits control the output directly and are not modified by the corresponding Digital I/O Invert/Toggle function. The bits in the Digital I/O Output Register 1 (08.073) only control the corresponding digital output if all the conditions below are met:
If the above conditions are not met, the digital output is controlled by the normal logic.
