The rotation direction selection can be set.
The rotation direction of a servo motor to position commands, speed commands, and torque commands can
be set. To set the rotation direction to position commands and speed commands, turn on or off both bits 6
and 7 of Polarity (607Eh) or use [Pr. PA14]. To set the rotation direction to torque commands, turn on or off
all of bits 5 to 7 of Polarity (607Eh), or use [Pr. PA14] and "POL reflection selection at torque mode" of [Pr.
PC29]. The following table shows the descriptions of Polarity (607Eh).

Selecting "degree (_ 2 _ _)" in "Position data unit" of [Pr. PT01] enables positioning to be performed on
modulo coordinates (rotary shafts). The following shows the differences when "degree" is selected.
Item (Index, Sub Index)
Description
Target position (607Ah, 0)
The range changes to between -360.000° to 360.000°.
Position actual value (6064h, 0)
The range changes to between 0° to 359.999°.
Software position limit (607Dh, 0)
The range changes to between 0° to 359.999°. When a value outside the
range is set, the value is clamped within the range of 0° to 359.999°.
Position range limit (607Bh, 0)
The range changes to between 0° to 359.999°.
