Setting Parameters
Rotation Direction (X axis:
402, Y axis: 802)
Position field sign
Positive (in direction of
increasing absolute
positions)
Negative (in direction of
decreasing absolute
positions)
! Caution
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.

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.
