r To ensure the correct direction at start-up, the speed controller is loaded with the
following starting torques:
r This results in the following behaviour depending on load and direction:
Feedforward control with memorised torque
[9-16] Feedforward control with parameterised starting torque
Lifting Lowering
Starting torque: C02586
= 50 Nm C02587 = 10 Nm
Lifting Lowering
Behaviour at max. load: Optimum behaviour Start-up a bit fast, but correct direction
(non-critical).
Behaviour without load: Start-up a bit fast, but correct direction
(non-critical).
Optimum behaviour
p C02588
: Waiting torque source
r When C02588 = 1, the starting torque
is the setpoint which has been
automatically memorised during the
last closing process (falling below the
speed threshold set in C02581
).

Note!
The higher the threshold for brake activation set in C02581, the higher is the
dynamic part in the marked torque (e.g. the speed-dependent friction torque).
In the special case that the load changes when the brake is closed, a correction
value, which is added to the marked torque, can be defined for the torque
precontrol via the input BRK_dnTorqueAdd_n.
