ACROMAG 651T-0600 Digital channel module

Command Trim Enable: When true, the proportional control attempts to match the position feedback to the position demand. This input is ignored if the SPC has not been configured as a proportional controller. Command Trim is disabled by the SPC if there is no valid feedback signal.POSSERR_OVR: Position Error Override: While true, prevents Position Error Fault 1 and Position Error Fault 2 from causing an alarm or shutdown. The SPC forces this input false if the DeviceNet link has failed. FBDIFF_OVR: Feedback Tracking Override: While true, prevents Feedback Tracking Fault 1 and Feedback Tracking Fault 2 from causing an alarm or shutdown. The SPC forces this input false if the DeviceNet link has failed.

This input is used if the SPC is configured for controller

 types P, PI, PI w/lag, or PI w/lead-lag, and ignored otherwise. It is limited to stay within the configured current range. This input is ignored if the SPC is not configured to Enable Remote Field Calibration. NULL_I_OFF: Null Current Offset (mA): Is added to the Actuator Null Current value to allow the operator to stroke the actuator during the open-loop portion of the field calibration procedure. Its value is limited so that the sum of the Null Current and Null Current Offset inputs will stay within the configured current range. This input is used if the SPC is configured for controller types P, PI, PI w/lag, or PI w/lead-lag, and ignored otherwise.

MA_MIN_POS

Min Position Current (mA): Determines the actuator current at 0 % position demand for the proportional controller. This input is only adjustable during the field calibration procedure. This input is used if the SPC is configured for controller type Proportional, and is ignored otherwise. This input is ignored if the SPC is not configured to Enable Remote Field Calibration. MA_MAX_POS: Min Position Current (mA): Determines the actuator current at 100 % position demand for the proportional controller. This input is only adjustable during the field calibration procedure.
