Operating in Manual Mode
Using Digital I/O Interface This section provides the information you need to operate your
8720MC drive in manual mode using a digital I/O interface. Before
beginning this procedure, scale the manual velocity analog reference
for the desire speed range and shaft direction.
To operate the 8720MC drive in manual mode using digital I/O
interface:
1. Using your voltmeter, verify that all analog reference signals
connected to analog inputs are set to zero.
2. Set the Auto/Manual Select digital input 4 high.
3. Enable the drive by setting the Drive Enable, digital input 1, high.
4. Set the digital input 6 to high in order to jog the motor.
Your drive is now ready to jog in the manual mode. The drive will
follow the reference signal voltage and polarity provided to analog
input 2. Refer to Appendix C.
Disabling the drive will stop the motor.
Operating in Manual Mode
with an Internal or External
HIM This section provides the information you need to operate your
8720MC drive with an internal or external HIM. Before beginning this
procedure, scale the manual velocity analog reference for the desired
motor speed range and shaft direction. Refer to Scaling of Manual
Velocity Analog Reference.
To operate the 8720MC drive in manual mode using an internal or
external HIM:
1. Enable the drive by setting the Drive Enable digital input 1 high.
2. Depress the red stop button on the HIM module. Use the speed
potentiometer or speed arrows on the HIM to set the speed
reference to zero.
3. Push the start or green HIM button to run the motor, or the jog
button to jog the motor.
4. Use the speed potentiometer or speed arrows to increase your
speed reference to a desired level.
Disabling the drive, pressing the HIM red stop button, or releasing the
jog button will stop the motor.
