ACH550-01 User's Manual

8120 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,

PFA 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.

0 =

NOT SEL – Disables the Interlock function. All digital inputs are

available for other purposes.

• Requires 8118

AUTOCHNG INTERV = 0.0 (The Autochange function

must be disabled if Interlock function is disabled.)
