76.42 Stop point 2 Defines the stop speed (Hz/rpm) for the second auxiliary
motor. See parameter 76.31 Stop point 1.
Vector:
800 rpm;
Scalar 25 Hz;
30 Hz
(95.20 b0)
76.43 Stop point 3 Defines the stop speed (Hz/rpm) for the third auxiliary motor.

Vector:
800 rpm;
Scalar 25 Hz;
30 Hz
(95.20 b0)
76.55 Start delay Defines a start delay for auxiliary motors. See parameter
76.31 Start point 1.
10.00 s
0.00…12600.00 s Time delay. 1 = 1 s
76.56 Stop delay Defines a stop delay for auxiliary motors. See parameter
76.31 Stop point 1.
10.00 s
0.00…12600.00 s Time delay. 1 = 1 s
76.57 PFC speed hold on Hold time for auxiliary motor switch-on. See parameter 76.31
Start point 1.
0.00 s
0.00…1000.00 s Time. 1 = 1 s
76.58 PFC speed hold off Hold time for auxiliary motor switch-off. See parameter 76.31
Stop point 1.
0.00 s
0.00…1000.00 s Time. 1 = 1 s
76.59 PFC contactor
delay
Start delay for the motor that is directly controlled by the drive.
This does not affect the starting of the auxiliary motors.
WARNING! There must always be a delay set if the
motors are equipped with star-delta starters. The
delay must be set longer than the time setting of the
starter. After the motor is switched on by the relay output of
the drive, there must be enough time for the star-delta starter
to first switch to star and then back to delta before the motor
is connected to the drive.
0.50 s
0.20…600.00 s Time delay. 1 = 1 s
76.60 PFC ramp
acceleration time
Defines the acceleration time for the drive motor speed
compensation, when an auxiliary motor is stopped. This ramp
time is also used for the drive motor to accelerate after an
autochange has occurred.
The parameter sets the ramp-up time as seconds from zero
to maximum frequency (not from the previous reference to
the new reference).
1.00 s
0.00…1800.00 s Time. 1 = 1 s
76.61 PFC ramp
deceleration time
Defines the deceleration time for the drive motor speed
compensation, when an auxiliary motor is started. This ramp
time is also used for the drive motor to decelerate after an
autochange has occurred.
The parameter sets the ramp-up time as seconds from
maximum to zero frequency (not from the previous reference
to the new reference).
