Code Description
8125 DEC IN AUX START
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
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
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.
