Risk of damage to device from excess volt‐
age at motor temperature evaluation input!
NOTICE
Only the allowed control voltage for the device is allowed at the motor tem‐
perature evaluation input. Excess voltage at the input can damage the de‐
vice.
Function
●
Monitoring motor temperature
●
Controlling motor holding brake
●
Analog output for connecting a motor fan frequency converter
Via an integrated contact element (BR), the power section
switches the voltage of the external 24 V supply to the output for
controlling the motor holding brake.
