APPENDIX B
Special Actual Values
By default, the
Actual Value
corresponds to the motor rotation speed in percentage.
Actual Value
can be attached some other monitored variable. Meaning of
Actual Value
can be selected
by resetting a Control Word bits 15...11. The user can choose to show one of the monitoring page
variables or the active fault code.
Control Word (bits 15...11) is binary coded as follows:
