Test with small load

Operating principle
The test mode function "Test with small load" is helpful during commissioning and when
troubleshooting, as the correct function of the application can be tested before installation in a
control cabinet or before the use of a motor provided for the application. The "Test with small
load" provides a way of checking the wiring of the control and main circuit with the aid of a small
motor (test motor).
