Acceleration/Deceleration Parameter: AccelMax

Description

This parameter is used to define the maximum acceleration applied to an axis.

The value of this acceleration is defined with the units UnitsAcceleration.

NOTE: The maximum acceleration must be greater than or equal to the current acceleration parameter.

NOTE: The maximum acceleration of the controlled speed drive (IDN standardized SERCOSS-0-0138 - Bipolar acceleration limit or IDN S-0-0136 - Positive acceleration limit) must be greater than the AccelerationMax parameter of the movement controller.

Related functions

The functions related to this parameter are:

GetAccelMax which sends a request to read the value of the current maximum acceleration,
SetAccelMax which sends a request to write the new maximum acceleration value.

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