L i n M o t ® Motion Control SW In the Temp Model Parameters section the regeneration resistor’s temperature model is defined. Parameter Name UPID Description C Resistor 1026h Heat capacity of the resistor winding itself. R Winding Housing 1027h Thermal resistance value between resistor winding and its housing. C Housing 1028h Heat capacity of the resistor housing. R Housing Environment 1029h Thermal resistance value between resistor housing and environment. Environment Temperature 102Ah Environmental temperature of the regeneration resistor. The figure below shows the implemented temperature model for the regeneration resistor. T R T H T Env R Resistor- R Housing- Housing Environment P RR C Resistor C Housing 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 Power Bridge 1BC6h Temperature of power driver Phase 1+ (E1100 only) 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) Page 94/105 User Manual Motion Control SW / 07.09.2011 NTI AG / <strong>LinMot</strong>
