(3) Selection of clear signal (CLR signal) [Pr.
429]
Use this function to make a drooping pulse 0 for
home position operation, etc.
When [Pr. 429 = 0], the deviation counter is cleared at
the edge of turning ON of the clear signal (CLR). The
CLR signal turns ON in synchronization with the zero
pulse signal of encoder for home position operation,
etc. and clears the deviation counter.
When [Pr. 429 = 1] (initial value), the deviation
counter is cleared while the clear signal (CLR) in ON.
For the terminal used for CLR signal input, set 69 in
any of [Pr. 178 to Pr. 189
selection] to assign the function.
