1.3 Restrictions on using a stepping motor
Note the following restrictions on using a stepping motor:
(1) For an axis where a stepping motor is connected, executing the S-curve
acceleration/deceleration may cause step-out.
Before using the S-curve acceleration/deceleration, confirm that step-out does
not occur.
Before using the S-curve acceleration/deceleration, confirm that step-out does
not occur.
(2) The circular interpolation control cannot be used for an axis where a stepping
motor is connected.
Although setting the bias speed at start is required by the characteristics of the
stepping motor, the setting of the bias speed at start is disabled for circular
interpolation control.
Therefore, when using the circular interpolation control, use servomotors for
both two axes.

(3) The backlash compensation function cannot be used for an axis where a
stepping motor is connected. If the function is used, the motor may lose steps.
