Position Limit and Modulo Parameter: RolloverLimit

Description

This parameter is used to define the positive and negative limits of the modulo of an axis.

The axis does not require the axis modulo to be enabled to use this function. This function does not activate the rollover. (Use the EnableRollover function). Rollover limits can be changed while an axis is enabled, but not while it is moving. The negative modulo limit must always be less than the positive modulo limit.

Associated Functions

The associated functions of this parameter are:

GetRolloverLimit which sends a read request for the actual positive and negative limit values (parameter function PARAM_CMD_1) of the designated axis,
SetRolloverLimit which sends a write request for the new positive and negative limit values (parameter function PARAM_CMD_1) of the designated axis.

These functions use, according to the language objects, the WRITE_CMD, READ_PARAM or WRITE_PARAM instructions.
