Description
Defines the start speed (Hz/rpm) for the second auxiliary
motor. See parameter 76.31 Start speed
Defines the start speed (Hz/rpm) for the third auxiliary motor.
See parameter 76.31 Start speed
Defines the stop speed (Hz/rpm) for the first auxiliary motor.
When the speed of the motor connected directly to the drive
falls below this value and one auxiliary motor is running, the
stop delay defined by parameter
If the speed is still at the same level or lower when the stop
delay elapses, the first auxiliary motor stops.
The running speed of the drive is increased by
- Stop speed 1] after the auxiliary motor stops
Speed/frequency
Defines the stop speed (Hz/rpm) for the second auxiliary
motor. See parameter 76.31 Stop speed
Defines the stop speed (Hz/rpm) for the third auxiliary motor.
See parameter 76.31 Stop speed
Defines a start delay for auxiliary motors. See parameter
76.31 Start speed 1.
Time delay.
Defines a stop delay for auxiliary motors. See parameter
76.31 Stop speed 1.
Time delay.
Hold time for auxiliary motor switch-on. See parameter
Start speed 1.
Time.
Hold time for auxiliary motor switch-off. See parameter
Stop speed 1.
Time.
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.
