7.4.4 Temperature Monitoring
The E1100 servo controller hardware contains eight absolute temperature sensors for
thermal protection. On the B1100 controller is one sensor placed.
Parameter Name UPID Description
Temp Sens Warn 1040h If the maximal board temperature rises above this level, a
Level
warning is generated (bit 6 in Warn Word is set).
Temp Sens Error
Level
1041h
If the maximal board temperature rises above this level, the
error is generated (error codes 10h..17h).
The table below shows the mapped variables of the temperature monitoring.
Variable Name UPID Description

Temp Ph1+
Power Bridge 1BC7h Temperature of power driver Phase 1- (E1100 only)
Temp Ph1-
Power Bridge 1BC8h Temperature of power driver Phase 2+ (E1100 only)
Temp Ph2+
Power Bridge 1BC9h Temperature of power driver Phase 2- (E1100 only)
Temp Ph2-
Power Bridge 1BC9h Temperature of power driver Phase 2+ (E1100 only)
