Jogging the Axis
EDC User's Manual Chapter: 5. Running
Section: How to Jog the Axis
Read the above section of the EDC User’s Manual before jogging each
active axis.
Power up the EDC Controller. No error messages should appear on the
screen. The red fault LED should remain OFF.
If an error message appears, refer to the EDC User’s Manual, Chapter 9:
Troubleshooting for an explanation of that error and troubleshooting
information.
Apply power to the actuator.
If an Excess Error message appears, disconnect power from the
actuator first and then from the Controller
The probable cause of this failure is incorrect phasing of the servo
command output to the actuator. Refer to the EDC User’s Manual,
Chapter 2: Installation, Servo Output Connections. Swap the Command
+ connection with the Command – connection.
Press the Mode key until the top line of the display reads RUN MODE,
then follow the directions in the above section of the EDC User’s Manual
to jog the axis.
If the actuator movement is sluggish, breaks into oscillation, or an
Excess Error fault occurs after the actuator begins to move, the problem
may be incorrectly set proportional gain (Kp). Refer to the EDC User’s
Manual, Chapter 3: Setup, Setting up Servo Loop Parameters.
• Setting Kp too low results in sluggish movement or an Excess
Error after the actuator begins to move.
• Setting Kp too high results in oscillation or erratic movement.
When the actuator jogs satisfactorily in both directions, the initial setup
is complete. Now you can return to the EDC User’s Manual to learn how
to tailor the EDC configuration and programming for your application.
