(3) Clear Signal Form Selection
The internal processing of the SERVOPACK for the clear signal can be set to either of four types by parameter
Pn200.1. Select according to the specifications of the machine or host controller.
(4) Clear Operation Selection
This parameter determines when the error pulse should be cleared according to the condition of the SERVO-
PACK, in addition to the clearing operation of the clear signal (CLR). Either of three clearing modes can be
selected with Pn200.2

Parameter Description Timing
Pn200 n.††0† Clears at high level.
Position error pulses do not accumulate while the
signal is at high level.
(Factory setting)
n.††1† Clears at the rising edge.
n.††2† Clears at low level.
Position error pulses do not accumulate while the
signal is at low level.
n.††3† Clears at the falling edge.
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 move 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.††2†, the
linear servo motor does not run even if a pulse-train command is entered.

Parameter Description
Pn200 n.†0†† Clear the error pulse during the baseblock. (Factory setting)
“During the baseblock” means when the SVON signal or the main circuit power supply is
OFF, or an alarm occurs.
n.†1†† Do not clear the error pulse. Clear only with the CLR signal.
n.†2†† Clear the error pulse when an alarm occurs.
