Functional Description

The parameter represents the maximum drive current (combination of servo amplifier / motor). This current can be reduced via the parameters UserDrivePeakCurrent, UserCurrentLimit, and DriveStopCurrentLimit.

Changes of UserDrivePeakCurrent are taken over by the Sercos phase up in MaxDrivePeakCurrent. Changes on UserCurrentLimit or DriveStopCurrentLimit have no effect on the parameter MaxDrivePeakCurrent.

NOTE: The parameter value is transferred from the slave to the master via the parameter channel of the Sercos by every access. Typically, this takes about 10 ms. However, up to 1 s can be realized if large amounts of data are transferred on the parameter channel. If the Sercos bus is in phase 0 or 1, then a default value is indicated here. If the Sercos bus is in phase 3 or 4, then the parameter value is transferred and indicated. In the Sercos phase 2, the parameter can be read through the application.

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.
