Restrictions on Using a Stepping Motor

Note the following restrictions on using a stepping motor:

• 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.

• The circular interpolation control and 3-axis helical 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. Ensure to

use a servomotor for all axes where interpolation controls are carried out when the circular interpolation

control or 3-axis helical interpolation control is carried out.

• 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.
