The following are executed when the clear operation is enabled.
• The SERVOPACK error counter is set to 0.
• Position loop operation is disabled.
→ Holding the clear status may cause the servo clamp to stop functioning and the servomotor to rotate slowly due to drift
in the speed loop.
When the clear signal (CLR) is not wired: Because position error pulses will be cleared when Pn200 is set to n.
linear servo motor does not run even if a pulse-train command is entered.
(4) Clear Operation Selection
This parameter determines when the error pulse should be cleared according to the condition of the
SERVOPACK, in addition to the clearing operation of the clear signal (CLR). Either of three clearing modes can
be selected with Pn200.2
