Functional Description

The parameter allows the configuration of the maximum ramp-down time when stopping the drive. Following expiration of the time, the PWM is switched off and the brake engages.

NOTE: The parameter value is transferred from the master to the slave via the parameter channel of the Sercos at every access. Typically, this takes about 10 ms. However, times up to 1 s may be realized if large amounts of data are transferred on the parameter channel.

The maximum ramp-down time is not monitored if asynchronous motors without encoder are used (in open-loop V / f control mode, ControlMode = open-loop control / 1).

Example:

Entering J_Load has a direct impact on the parameter MaxAcc. A revision of MaxAcc only has an impact on ControllerStopDec if,

a Sercos phase up takes place or
the parameter ControllerStopDec is modified.
