7.1.5. Clearing Position Error Counter (CLR)
l In case of the B3 and 23 Driver Units, this function is available to the Input/Output combination
type TY4.
l The CLR (clear) input clears the internal position error counter.
l When performing Home Return with a sequence of the master controller, inputting the CLR
signal to clear the position error counter simultaneously with detection of øZ signal will help to
attain high repeatability of the home position.
l When the excess position error alarm occurs, turning ON the CLR input clears the position error
counter and thereby recovering the System from the alarm state.
* The CLR signal is an edge-triggered input. Therefore, the function of error counter is active even
the CRL input remains ON once it cleared the errors.
