PROGRAM DIAGNOSTICS MENU

This Menu allows testing of the various MDC inputs and outputs. It is

especially useful after unit installation to independently test the operation of

external switches, relays, the feedback transducer, and the motor drive system.

The following flowchart shows only the Diagnostics portion:

TEST INPUTS

The MDC displays an alphanumeric character to indicate a Dedicated

Function Input or a User Input is active. This allows the user to check switch

operation and wiring connections to the Inputs. It is made up of two sections.

READ INP (read inputs) shows the state of the dedicated control inputs.

READ USR (read user) shows the state of the programmable User Inputs. A

“--” displayed on line 2 indicates that the input is inactive and an

alphanumeric character indicates that the input is active. All of the inputs

except F-STOP and R-STOP are active when pulled to common. F-STOP and

R-STOP are active when left floating.

R=RUN, S=RAMP STOP, F=FSTOP, J=JOG, O=OPEN LOOP
