AC
FUNCTION: Acceleration
DESCRIPTION:
The Acceleration (AC) command sets the linear acceleration rate for independent moves, such
as PR, PA and JG moves. The parameters input will be rounded down to the nearest
factor of 1024. The units of the parameters are counts per second squared. The
acceleration rate may be changed during motion. The DC command is used to specify
the deceleration rate.

V=_AC
Assigns the current acceleration setting to the variable V
HINTS: Specify realistic acceleration rates based on your physical system such as motor torque
rating, loads, and amplifier current rating. Specifying an excessive acceleration will cause large
following error during acceleration and the motor will not follow the commanded profile. The
acceleration feedforward command FA will help minimize the error.
