Replacing the drive controller
DANGER!
Electrical voltage! Risk of fatal injury due to electric shock!
▪
Always switch off all power supply voltage before working on the devices!
▪
Note the discharge time of the DC link capacitors. You can only determine the absence of
voltage after this time period.
ATTENTION!
Loss of absolute position!
The absolute position in the encoder is lost if the encoder cable is disconnected from the AES
battery module.
▪
Do not disconnect the encoder cable from the AES during service work! Disconnect the
AES from the drive controller.
Information
