[5-28] Signal flow of the "Inverter-motor brake" function
The additive speed setpoint (C00987) should be 1 … 4 times the slip of the machine:
[5-29] Formula for calculating the additive speed setpoint
Generally applies to the "Inverter-motor brake" function:
The regenerative energy converted in the motor and therefore faster deceleration can
be achieved by increasing the additive speed setpoint as well as by reducing the filter
time constant (C00988
).
Torque oscillations can occur due to the dynamics of traversing. Mechanical vibrations
can be reduced by lowering the additive speed setpoint (C00987
) or by increasing the
filter time constant (C00988
).
