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.

Sets the actual number of PFA controlled motors (maximum 6 motors, 1 speed regulated, 3 connected direct-on-line
and 2 spare motors).
• This value includes also the speed regulated motor.
• This value must be compatible with number of relays allocated to PFA 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
PFA but it needs to be included in this value.
