Deviation Counter Reset (ECRST)
The CN1 connector input pins are as follows:
+Deviation Counter Reset (8: +ECRST)
− Deviation Counter Reset (9: –ECRST)
Functions
•
The value of the deviation counter will be reset when the deviation counter reset signal
turns ON and the position loop will be disabled.
• Input the reset signal for 20 µs minimum. The counter will not be reset if the signal is
too short.
RUN Command Input (RUN)
RUN Command Input (pin 6: RUN)
Functions
This is the input that turns ON the power drive circuit for the main circuit of the Servo
Driver. If this signal is not input (i.e., servo-OFF status), the Servomotor cannot operate
except for JOG operations.
