(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 rotate slowly due to drift
in the speed loop.
If the clear signal (CLR) is not wired and Pn200 is set to n.
2
, the position-error pulse is always cleared.
So, if a pulse-train reference is input, the servomotor will not operate.

Parameter
Description
Pn200
n.
0
Clear the error pulse at the CLR signal input during the baseblock. (Factory setting)
“During the baseblock” means when the /S-ON 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 or the CLR signal is input.
