LOGIC CONTROL
This section addresses the four digital inputs that control the ML-Drive's operating
state. Logic Control also addresses one digital output.
The four digital inputs are F–Stop, R–Stop, Run and Jog. When the ML-Drive is
powered up, it defaults to R–Stop. If either Run or Jog have been hardwired, the
ML-Drive will operate in either Run or Jog instead of R–Stop. Run is hardwired by
shorting Run, R–Stop and F–Stop to common. Jog is hardwired by shorting Jog,
R–Stop, and F–Stop to common.
The one digital output is Drive Enable. The Drive Enable output indicates the state of
the drive output.
The sections that follow demonstrate how to use the digital inputs and the Drive Enable
output.
Caution
Do not use the AC line power
to start or stop the system.
Use the Digital Inputs to start or stop
the system.
