Error management

Overview
The motor controllers of the CMMS family offer the option to change the error response of individual
events, e.g. the occurrence of a following error. As a result, the motor controller reacts differently when
a certain event occurs: Depending on the setting, braking down can occur with the output stage being
shut off immediately or a warning being shown on the display.
For every event, a minimum reaction is intended by the manufacturer, which cannot be fallen below.
And so "critical" errors, such as 60-0 short circuit output stage, are not reparametrised, since here an
immediate switch-off is necessary to protect the motor controller from possible destruction.
If a lower error response is entered than is permissible for the respective error, the value is limited to
the lowest permissible error response. A list of all error numbers is found in chapter A
" Diagnostic messages".
