7.2.1 Lift-dedicated digital output functions
Several specific functions can be programmed on the drive digital outputs, in order to check the correctness of the lift
sequence and to improve the interaction with the external sequencer. Here follows a list of the functions that can be useful
in lift applications.
DO Programming code Function description
[0] Drive ready TRUE when the drive is ready to accept a valid RUN command. Meaning that the drive is
not in alarm, the dc-link pre-charge is completed and the safe-start interlock logic is
cleared.
[1] Alarm state TRUE when the drive is in alarm status. Alarm reset is needed to restore operation
[2] Not in alarm TRUE when the drive is not in Alarm status.
[3] Motor run TRUE when the inverter output bridge is enabled and operating.
[4] Motor stop TRUE when the inverter output bridge is not operating (all six switches are open).
[5] Rev rotation TRUE when the motor is rotating counter-clockwise.
[31] Freq > thr1 TRUE when the motor speed (measured or estimated) is above the threshold defined by
parameters P.440 and P.441.
[32] Freq < thr1 TRUE when the motor speed (measured or estimated) is below the threshold defined by
parameters P.440 and P.441. This function is normally used to detect zero speed (see
sequence in Fig.7.2). This signal is available as default on terminal 17, Digital output 2.
[45] DC braking TRUE when DC injection is in progress.
[51] Contactor TRUE when the Run contactor has to be closed, either for upward or downward motion.
