7.2.1 Lift-dedicated digital output functions
Several specic 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 dened
by parameters P.440 and P.441.
[32] Freq < thr1 TRUE when the motor speed (measured or estimated) is below the threshold dened by
parameters P.440 and P.441. This function is normally used to detect zero speed (see
sequence in Fig.7.2).
[45] DC braking TRUE when DC injection is in progress.
