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
[0] Drive ready
[1] Alarm state
[2] Not in alarm
[3] Motor run
[4] Motor stop
[5] Rev rotation
[31] Freq > thr1
[32] Freq < thr1
[45] DC braking
[51] Contactor

Function description
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.
TRUE when the drive is in alarm status. Alarm reset is needed to restore operation
TRUE when the drive is not in Alarm status.
TRUE when the inverter output bridge is enabled and operating.
TRUE when the inverter output bridge is not operating (all six switches are open).
TRUE when the motor is rotating counter-clockwise.
TRUE when the motor speed (measured or estimated) is above the threshold defined by
parameters P.440 and P.441.
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.
TRUE when DC injection is in progress.
TRUE when the Run contactor has to be closed, either for upward or downward motion.
