5.9.3.3 Temperature monitoring of a second motor
This function is available from software version V7.0!
From software version V7.0 onwards, two motor temperature sensors can be evaluated
simultaneously via the two encoder inputs X7 and X8 when two motor are used (e.g. double motor
for a storage and retrieval unit). For this purpose, the selection "X7 and X8 in parallel" must be set
as feedback system for the motor temperature in C01193 .
• In this case, always the higher temperature of the two detected temperatures is displayed as the
current motor temperature on the Diagnostics tab and in C00063 .
• Moreover, the following display parameters are available from software version V6.0 onwards:
• C01200/1 : Motor temperature via X7
• C01200/2 : Motor temperature via X8
• If one of the two detected temperatures exceeds the limit value set in C00121 , the response set
in C00584 is activated as advance warning.
• In the Lenze setting the "Warning" response occurs if one of the two winding temperature
exceeds 120 °C.
• As soon as one of the two detected temperatures exceeds the fixed limit value of 150 °C, the
response set in C00583 is activated (default setting: "Fault").
• If an open circuit is detected in one of the two motor temperature sensors, the response set in
C00594 (default setting: "Fault") is activated.
• It is not possible to set different responses for the two temperature monitoring modes.
• For the motor model in the controller, the mean value of both detected temperatures is used.
