Code Description
8120 INTERLOCKS
Defines operation of the Interlock function. When the Interlock function is enabled:
• An interlock is active when its command signal is absent.
• An interlock is inactive when its command signal is present.
• The ACS550 will not start if a start command occurs when the speed regulated motor's interlock is active – the
control panel displays an alarm (2015,
Wire each Interlock circuit as follows:
• Wire a contact of the motor's On/Off switch to the Interlock circuit – the drive's PFC logic can then recognize that
the motor is switched off, and start the next available motor.
• Wire a contact of the motor thermal relay (or other protective device in the motor circuit) to the Interlock input – the
drive's PFC logic can then recognize that a motor fault is activated and stop the motor.
0 = – Disables the Interlock function. All digital inputs are available for other purposes.
