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 Group 22:
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 applies.
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 Group 22
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 applies.

• A = speed regulated motor accelerating using Group 22
parameters (2202 or 2205).
• B = speed regulated motor decelerating using Group 22
parameters (2203 or 2206).
• At aux. motor start, speed regulated motor decelerates
using 8125
DEC IN AUX START
• At aux. motor stop, speed regulated motor accelerates
