The following items will be changed in the SERVOPACK after the error counter has been reset to zero.
• The SERVOPACK error counter is set to 0.
• The position loop operation is disabled.
Note: Holding the clear status may cause the servolock to stop functioning and the servomotor to rotate slowly due to drift
in the speed loop.
Pulse Width of Clear Signal
When parameter Pn200.1 is set to 0 or 2, the width of the clear signal must be at least 250 μs to reset the error
counter.
When parameter Pn200.1 is set to 1 or 3, the width of the clear signal must be at least 20 μs to reset the error
counter.
(3) Clear Operation
This parameter determines when the position error should be set to zero according to the condition of the SER-
VOPACK. Any of three clearing modes can be selected with Pn200.2.
