Preconditions for the execution
• The motor must be able to rotate freely.
• The controller is free of errors and is in the "
" device status.
Response of the motor during the execution
The motor rotates as a function of the set output frequency.
How to activate the manual test mode "voltage/frequency":
1. If the controller is enabled, inhibit the controller.
Enable/inhibit operation via control word
2. Set object
(or
for axis B) to "1" to change to the "Voltage/frequency" test
mode.
3. Enable the controller to start the test mode.
4. To stop the test mode:
• Inhibit controller.
• Set object
(or
for axis B) to "0" to change back to the CiA402 mode.
5.3.2
Manual test mode "current/frequency"
Functional description
In this test mode, three phase currents are injected in the connected motor after controller enable.
• Via the following objects, the test mode can be adapted:
• The current phase currents can be read via the following objects:
Advantages compared to the manual test mode "voltage/frequency":
• The current does not set freely, but is controlled to a defined value.
• If a synchronous motor is connected, the generated torque can be predicted.
