Using the OIM to Monitor and
Control the Drive
The OIM allows you to monitor the speed, armature voltage, load, and current keypad
reference outputs to the motor. You can choose between two viewing options.
The OIM also allows you to control the drive. Motor control options available through
the OIM include starting, stopping, jogging, and setting the manual reference and
control source.
6.1 Using the OIM to Monitor Drive Outputs
You can monitor two or four drive outputs when the OIM is in monitor mode. A sample
of the four-output monitor mode screen is shown in figure 6.1.
6.1.1 Description of the Monitor Mode Outputs
You can monitor:
•
MOTOR SPEED : The actual motor speed as measured by a speed feedback device.
Displayed as a percentage, RPM , or user-scaled units.
•
ARM VOLTS : The actual armature voltage.
•
MOTOR LOAD : The actual motor load (armature current) in percent full load amps
(% FLA ) or amps. The resolution of this output depends on the setting of MOTOR
RATED ARM AMPS (P.008). For values of less than 1000.0 amps, motor load is
displayed with 0.1 amps resolution. For values more than or equal to 1000.0 amps,
motor load is displayed with 1 amp resolution.
•
REF : The reference. This is the speed or torque the drive attempts to reach when the
drive is running. The control source is indicated in the label. For example, in
figure 6.1, the reference is from the keypad.
