Slave Group Parameter: FollowerRatio

Description

This parameter is used to change the Ratio of the specified slave axis.

The ratio numerator indicates how much the slave will move when the master axis moves the distance showing on the denominator. The ratio value can be modified at any time.

The Ratio DOES NOT CHANGE instantaneously in order to obtain a smooth movement when the slave is activated and the following movement takes place.

Associated Functions

The associated functions of this parameter are:

GetFollowerRatio which sends a read request for the tolerance of the actual position of the designated axis,
SetFollowerRatio which sends a write request for the tolerance of the actual position of the designated axis,

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