WARNING
Electric shock in the event of voltage flashovers at the temperature sensor
Voltage flashovers to the signal electronics can occur in motors without safe electrical
separation of the temperature sensors.
• Use temperature sensors that comply with the specifications relating to safe electrical
separation.

1)
A controller compares the encoder system supply voltage - sensed via the remote sense cables - with the reference
supply voltage of the encoder system, and adjusts the supply voltage for the encoder system at the output of the drive
module until the required supply voltage is obtained directly at the encoder system.
