05.07 – PRE-TORQUE
The Pre-torque function helps ensure a linear start without any jerk. This is done by setting torque to a value
corresponding to the load before opening the brake. The initial torque value applied to the motor, as well as the direction
of applied torque, can be supplied by installing a load cell on the lift car. The load cell signal is acquired via analog input
and is appropriately scaled if the pre-torque is used.
If there is no load cell, the system can work with a fixed torque value and supply only torque direction. In this case, the
fixed torque value is optimized only for a load condition.

Init pre-torque
Setting of reference value used in pre-torque function only if the
parameter lets you optimize the pre-torque function only for a load condition. Use the fieldbus to change the setting of this
parameter to optimize the pre-torque function for other load situations.
