P Hz
Setting range: 0.0 – 0.2 – 5.0 s
This parameter determines how long the motor will remain at preset speed 7 speed after
successful premagnetisation of the motor and brake has to release.
Setting range: 0.0 – 5.0 s
This parameter can be used to set the time required for the mechanical brake to apply.
This parameter prevents a sagging of the drive especially for hoists.
Setting range: 0.0 – 1.0 – 200 %
Sets the torque level in % of maximum available that must be generated prior to release
of the motor brake.
This is used to ensure that the motor is connected and the torque generated to prevent
the load dropping when the brake is released. In V/F mode the torque prove is not active.
This is only recommended for horizontal moving applications.
P4-16 Torque
threshold timeout
Setting range: 0.0 – 5.0 s
sets the time for which following a start command, the drive will attempt to apply enough
torque to the motor to reach the torque threshold for brake release level set in Parameter
P4-15. Should the torque level not be reached within the set time, due to a mechanical
or other fault, the drive will trip.
