Application example:
The load for a hoist drive is always known. For an optimum behaviour a torque
proportional to the load and 10 Nm in addition as constant precontrol value are to be
loaded in the speed controller.
r The starting torque 1 is used as constant precontrol value ( C02586 ="10 Nm",
C02588 = "0" and BRK_bStartingTorque2 = FALSE).
r Via the input BRK_dnTorqueAdd_n the torque is specified proportional to the load.
r An additional precontrol value can be
set via the input BRK_dnTorqueAdd_n.
