6.9.3.3 Temperature monitoring of a second motor
Two motor temperature sensors can be evaluated simultaneously via the two encoder inputs X7
and X8 when two motors 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 .
• In addition, the following display parameters exist:
• 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.
