170 ACQ550-U1 User’s Manual
Parameters
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 ACQ550 will not start if a start command occurs when the speed regulated motor’s interlock is active – the
control panel displays an alarm (2015,
PFC 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 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 =
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.)
1 =
DI
1 – Enables the Interlock function and assigns a digital input (starting with
DI
1) to the interlock signal for each
PFC relay. These assignments are defined in the following table and depend on:
• the number of PFC relays [number of parameters 1401…1403 and 1410…1412 with value = 31 (
PFC
)]
• the Autochange function status (disabled if 8118
AUTOCHNG INTERV
= 0.0, and otherwise enabled).
