Relates to the position field sign bit. This parameter designates the control
voltage as positive or negative. The position field sign establishes the posi-
tion field as positive or negative.

The following table shows the relationship between the sign designated for
the positioning action, the rotation direction designated above, the motor driv-
er voltage, and the direction of motor rotation.

Determine in this area if a positive or
negative control voltage is required.
Caution
Erroneous settings for this parameter can cause the servomotor system to run
out of control. Change these settings immediately after turning on power when
the motor is not engaged to a load.
