Operation Modes
This section describes the operation modes available in the MxC, and how to switch between modes.
‹ MxC Modes
Parameters and monitoring functions in the MxC are organized into groups called “modes”. These modes
make it easier to read and set parameters. Their are five separate modes available in the MxC.
The five modes and their primary functions are shown in the Table 3.3.
* Always perform Auto-Tuning with the motor before operating in Open Loop or Flux Vector Control. The Auto-Tuning Mode cannot be entered while the
MxC is running, or when an error has occurred. The default setting of the MxC is for Open Loop Vector Control (A1-02 = 2).
Table 3.3 Modes
Mode Primary functions
Drive Mode
A Run Command may be entered to start the motor when viewing this mode.
Use this mode when monitoring values such as frequency references or output cur-
rent, displaying fault information, or displaying the fault history.
Quick Programming Mode
Use this mode to set and monitor the most commonly used parameters, as well as
operate the MxC.
Advanced Programming Mode Use this mode to reference and set all parameters.
Verify Mode
Use this mode to read/set parameters that have been changed from their original
default values.
Auto-Tuning Mode*
Use this mode when running a motor with unknown motor characteristics in Open
Loop or Flux Vector Control. In this mode, the MxC automatically calculates the
motor characteristics, then enters those values to the motor parameters.
Also used to measure the motor line-to-line resistance.
