(3) Selection of clear signal (Pr. 429, CLR signal)

⋅ Use this function to zero the droop pulse for home position operation, etc.
⋅ When "0" is set in Pr. 429 , the deviation counter is cleared at the edge of turning ON of the clear signal (CLR). In

addition, the CLR signal turns ON in synchronization with zero pulse signal of the encoder at home position
operation, etc., deviation counter is cleared.

⋅ For the terminal used for CLR signal, set "69" in any of Pr. 178 to Pr. 189 (input terminal function selection) to assign

the function.

(4) Pulse monitor selection (Pr. 430 )

The status of various pulses during running is displayed.
Set "0" in Pr. 52 DU/PU main display data selection to display output frequency monitor.

⋅ Count the number of pulses when the servo is ON.
⋅ The cumulative pulse value is cleared when the base is shut off or the clear signal (CLR) is turned ON.

⋅ Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Set

parameters after confirming the function of each terminal.
