Analog / Encoder Monitor.
This screen monitors the analog input & output, as well as the raw encoder value input. Additionally,
the encoder can be connected to an alternate PLC input to help troubleshoot encoder problems. To change the
encoder input, disconnect power & move the encoder signal wire from input 0 to any of inputs 1, 2, or 3.
Restore power, navigate back to this screen, and change the “ENC CH” # to match the PLC input chosen.
When the “Jog Mtr” button is pressed, the motor will run at 25% speed for as long as the button is
pressed. The top line will display the raw encoder value. The “MTR OUT” value will be 500 for KB or Bodine
drives, or 1000 for Dart drives. The “PRESS” value will be 0-4000, depending on the press signal, if no press
signal is connected, the value will be at or near zero.
