LOGIC CONTROL
This section addresses the six digital inputs that control the CX-1200's operating state.
The six digital inputs ( listed in by priority) are:
F-Stop
R-Stop
H-Stop
R u n
Jog Forward
Jog Reverse
When the CX-1200 is powered up, it defaults to R-Stop. If either Run or Jog have been hardwired, the CX-
1200 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 Forward or Jog Reverse are hardwired by shorting Jog, R-Stop, and F-Stop to
common.
Run is terminated by activating F-Stop, R-Stop, or H-Stop. The operating state changes to the input that
terminated Run, provided that another input is not subsequently activated. Jog Forward or Jog Reverse are
terminated by deactivating the Jog Forward or Jog Reverse inputs. Jog Forward or Jog Reverse can also be
terminated by activating F-Stop, R-Stop, or H-Stop. The operating state automatically changes to R-Stop
after the Jog ramp is completed. You can not enter Run from Jog with the Jog inputs active. However, you
can enter Run during a deceleration from Jog after the Jog input is deactivated. You can not enter Jog
Forward or Jog Reverse from Run. If two or more inputs become active at the same time, the input with the
highest priority will dictate the operating state.
The sections that follow demonstrate how to use the digital inputs.
