Code Description
8124 ACC IN AUX STOP
Sets the PFC acceleration time for a zero-to-maximum
frequency ramp. This PFC acceleration ramp:
• Applies to the speed regulated motor, when an auxiliary
motor is switched off.
• Replaces the acceleration ramp defined in
ACCEL/DECEL.
• Applies only until the output of the regulated motor
increases by an amount equal to the output of the
switched off auxiliary motor. Then the acceleration ramp
defined in Group 22: ACCEL/DECEL
0 = .
NOT SEL
0.1...1800 – Activates this function using the value
entered as the acceleration time.
8125 DEC IN AUX START
Sets the PFC deceleration time for a maximum-to-zero
frequency ramp. This PFC deceleration ramp:
• Applies to the speed regulated motor, when an auxiliary
motor is switched on.
• Replaces the deceleration ramp defined in
ACCEL/DECEL.
• Applies only until the output of the regulated motor
decreases by an amount equal to the output of the
auxiliary motor. Then the deceleration ramp defined in
Group 22: ACCEL/DECEL
0 = .
NOT SEL
0.1...1800 – Activates this function using the value
entered as the deceleration time.
8126 TIMED AUTOCHNG
Sets the autochange using a Timed function. See parameter 8119
0 = .
NOT SEL
1 = 1 – Enables autochange when Timed function 1 is active.
TIMED FUNC
2...4 = 2...4 – Enables autochange when Timed function 2...4 is active.
TIMED FUNC
8127 MOTORS
Sets the actual number of PFC controlled motors (maximum 7 motors, 1 speed regulated, 3 connected direct-on-line
and 3 spare motors).
• This value includes also the speed regulated motor.
• This value must be compatible with the number of relays allocated to PFC if the Autochange function is used.
• If Autochange function is not used, the speed regulated motor does not need to have a relay output allocated to
PFC but it needs to be included in this value.
8128 AUX START ORDER
Sets the start order of the auxiliary motors.
1 = – Time sharing is active. Evens out the cumulative run time of the auxiliary motors. The start order
EVEN RUNTIME
depends on the run time: The auxiliary motor whose cumulative run time is shortest is started first, then the motor
whose cumulative run time is the second shortest etc. When the demand drops, the first motor to be stopped is the
one whose cumulative run time is longest.
2 = – The start order is fixed to be the order of the relays.
