1.4 Friction offset test
A friction offset test is conducted after activating the control unit, this test being governed by the spindle constants. The spindle is run in both rotational directions during a defined period of time. This can be detected by a low motor noise. An error message is generated in the event of a malfunction (e.g. if friction is too high) and the control unit is stopped. After activation, the friction offset test can be suppressed if desired by adapting the spindle constants. The main menu subsequently appears.
A friction offset test should be carried out daily. Program “0” has to be selected.
