INTERLOCKS
0…6
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 ACH550 will not start if a start command occurs when the speed
regulated motor’s interlock is active – the control panel displays an
alarm (2015,

I
LOCK
).
Wire each Interlock circuit as follows:
• Wire a contact of the motor’s On/Off switch to the Interlock circuit –
the drive’s PFA logic can then recognise 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 PFA logic can then
recognise that a motor fault is activated and stop the motor.
