Hoist pretension
Option | Meaning |
|---|---|
Save | The value that was present at the time of opening the speed control loop is retained. If the load torque has not changed, no adjustment is necessary when closing the speed control loop. |
Off | The integrator always starts with the value "0". Adjustment is made to an existing load torque. The speed controller can usually compensate for sagging of the hoist without additional settings. |
Initialization value | If the load torque is known, you can specify this to the speed controller as an initial value via the parameter "Torque preload" in the range -1000% to 1000% of the nominal motor torque. |
