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
