12.3 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 in the general technical data. 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.
CAUTION!
Risk of damage to property due to electrostatic discharge!
Take appropriate measures when handling exposed circuit boards, e.g. wearing ESD-safe
clothing.
Do not touch contact surfaces.

The safety module is a permanently integrated component in the drive controller where any
design, technical and electrical modifications are prohibited!
