0.1…1800 = Activates this function using the value entered as the acceleration time.
• 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 using 8124
ACC IN AUX STOP
.
8125 DEC IN AUX START 0.0…1800.0 s 0.1 s 0.0 s
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.
8126 TIMED AUTOCHANGE 0…4 1 0
Sets the autochange with timer. When enables, autochange is controlled with the timer functions.
0 =
NOT SEL
.
1 = Timer 1 – Enables autochange when Timer 1 is active.
2…4 Timer 2…4 – Enables autochange when Timer 2…4 is active.
8127 ACT NR OF MOT 0, 1, 4 1 2 9
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.
