Feedback Frequency
(J5 pins 4, 5)
The Feedback Frequency is a pulse
train input that the ML–Trim uses to
determine the speed of the follower
motor. For signal level specifications
refer to
References: Appendix A ,
ML–Trim Specifications, page A-1.
Run (J5 pins 6, 8)
When the Run input (J5 pin 6) is
momentarily shorted to common, the
ML–Trim 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–Trim will not enter
“Run”.

If the Feedback Frequency is lost,
the ML-Trim will command a 100% Speed Out
and the motor will run at 100% capacity.
This can cause severe injury, death or
equipment damage.
