5.1 Settings According to Device Characteristics
This section describes the procedure for setting parameters according to the dimensions
and performance characteristics of the equipment used.
5.1.1 Switching Servomotor Rotation Direction
The servo amplifier has a Reverse Rotation Mode that reverses the direction of
servomotor rotation without rewiring. Forward rotation in the standard setting is
defined as counterclockwise as viewed from the load.
With the Reverse Rotation Mode, the direction of servomotor rotation can be
reversed without changing other parameters. Only the direction (+, −) of shaft
motion is reversed.
 Setting Reverse Rotation Mode
Use the parameter Pn000.0.
Use the following settings to select the direction of servomotor rotation.
