Electrical connection (example)
DANGERDue to the DC link capacitors dangerous voltage may persist at the DC link contacts "X02" after the servo drive has been disconnected from the mains supply. Wait 5 minutes after disconnection and measure the voltage on the DC link contacts DC+ and DC-. The device is safe once the voltage has fallen below 50 V.
The example below describes the brake module and several servo drives, which are linked via AX-Bridge modules to make up a drive system. We recommend that the brake module be placed in the first position with the AX-Bridge power supply module (AX5901) and after that the servo drives with decreasing rated current; we assume here that the most powerful servo drive also releases the greatest brake energy.
Please analyze your application. The brake module should always be placed directly beside the servo drive that releases the greatest brake energy. This rule should also be applied if several brake modules are used in a drive system.

CAUTIONIf the drive system is disconnected from the mains due to a mains failure, all axes of the drive system make uncontrolled movements. Take suitable measures to ensure than no persons are endangered during this time. Vertical axes are particularly dangerous.
