ACC IN AUX STOP
0.0 … 1800.0 s 0.1 s 0.0
Sets the PFA acceleration time for a zero-to-maximum frequency ramp. This PFA
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.
0 = NOT SEL
0.1…1800 = Activates this function using the value entered as the acceleration time.
• A = speed regulated motor accelerating using Group 22: Accel/Decel parameters
(2202 or 2205).
• B = speed regulated motor decelerating using Group 22: Accel/Decel parameters
(2203 or 2206).
• At aux. motor start, speed regulated motor decelerates using parameter 8125 DEC
IN AUX START.At aux. motor stop, speed regulated motor accelerates using param-
eter 8124 ACC IN AUX STOP.

DEC IN AUX START
0.0 … 1800.0 s 0.1 s 0.0
Sets the PFA deceleration time for a maximum-to-zero frequency ramp. This PFA
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.
0 = NOT SEL
0.1…1800 = Activates this function using the value entered as the acceleration time.
