Display Parameters
DISPLAY PARAMETERS
The Display parameters, described in the following tables, can be viewed in any access level from the Display Menu. Use the arrow keys on the keypad display or programming terminal to scroll through this parameter set. The following parameters can be viewed under Drive State in the Display Menu. They are used for monitoring drive controller operation.
Parameter | STATUS | Description |
|
|
|
Drive State | RDY | Drive controller is ready to run. |
|
|
|
| RUN | Drive controller and motor are running in a steady state. |
|
|
|
| ACC | Drive controller is accelerating the motor. |
|
|
|
| DEC | Drive controller is decelerating the motor. |
|
|
|
| CLI | Drive controller is in current limit. |
|
|
|
| DCB | Drive controller is injecting DC current for braking the motor. |
|
|
|
| NST | Drive controller has been commanded to freewheel stop. |
|
|
|
| OBR | Drive controller is decelerating the motor as fast as possible. |
|
|
|
The following parameters can also be viewed from the Display Menu.
