The Enable and Disable buttons allow you to enable or disable the drive's servo loops depending on the
current state. If the drive is disabled, the Enable button is active and the Disable button is inactive (grayed
out). On the other hand, if the drive is enabled, the Disable button is active and the Enable button is inactive.
Forward and Reverse Buttons
The Forward and Reverse buttons are active when the drive is enabled and inactive when the drive is disabled.
They allow the direction of the jog to be altered as needed. The current direction is constantly updated on the
Direction indicator on the left side of the screen.
Changing the direction in Operator mode changes the direction of all motion that will be executed next, in
IMPORTANT
Program mode or Operator mode. If an operator swaps the direction in Operator mode, changes the Simple
Motion Control CCBB back to Program mode, and runs the Axis User Program, the direction of the move or
jog will be in this newly-set direction unless the Axis User Program re-initializes it in PLC code.
Jog Button
The Jog button is active when the drive is enabled and inactive when the drive is disabled. When pressed, the
PLC program sends a jog command to the drive in the direction that is currently selected at the speed that is
currently entered in the Operator Speed numeric entry. The Jog button is a momentary button and therefore
the jog will stop executing when the button is released.
Operator Speed
The Operator Speed numeric entry allows entry of a jog speed that is sent to the drive via the PLC while the
Simple Motion Control CCBB is in Operator mode.
Although the MicroLogix 1400 controller sends Pulse Train Output pulses to the drive at a specified
frequency (Hz), the PLC program performs the appropriate scaling to allow you to enter and display the
corresponding speed in RPM.
Just entering an Operator Speed doesn't execute a jog at that desired speed. The axis must be enabled and
TIP
Jog must be pressed in order for a jog command at the Operator Speed to be sent to the drive.
Test the Operator Mode Functionality
Follow this procedure to test your axis by using the Simple Motion Control Operator mode functionality.
1. Verify that the motor is disconnected from the load (open shaft) and is safe to jog.
2. Enable the Ultra1500 drive by pressing Enable.
