• cable
Supply Unit
• wiring
• 24V supply voltage
• mains voltage 3 * 400V
Drive Controller
• note down error number
• wiring
• 24V supply voltage
• mains voltage 3 * 400V
Encoder
• You can check the encoder signals by means of the oscilloscope
function of the firmware
Cables
• encoder cable
• motor cable
• input and output cables incl. 24V supply voltage
• cables of the master communication
Peripheral Equipment
• mains connection / switch-on logic
• mechanics (rough running, loose connections, …)

Replacing Devices
Note: For replacing devices you absolutely have to observe the
safety instructions contained in chapter 3!
Replacing the Motor
• Eventually note down the last absolute value.
