Feedback Frequency
(J4 pins 4, 5)
The Feedback Frequency is a pulse
train input that the ML-Drive uses to
determine the speed of the follower
motor. For signal level specifications
refer to
References: Appendix A ,
ML-Drive Specifications, page A-1.
Run (J4 pins 6, 8)
When the Run input (J4 pin 6) is
momentarily shorted to common, the
ML-Drive enters Run. As a
momentary input, Run is internally
latched and does not need to be
maintained by an operator device.
NOTE: Close the R–Stop and F–Stop
inputs prior to entering Run.
If you are only using one of
the Stop inputs, wire short the
other Stop input to common
or the ML-Drive will not enter
“Run”.

DANGER !
If the Feedback Frequency is lost,
the ML-Drive will command a 100% speed out
and the motor will run at 100% capacity.
This can damage your equipment or
cause severe injury or death.
