Power Supply Motor:
Wiring: 2.5 mm² (AWG12), max length 5 m
Supply Voltage 48...72 VDC. Absolute max. Rating 72VDC + 5%
Supply voltage for PWR Signal and PWR Motor may be different
Motor Supply GND must be externally connected to earth
Power Supply Signal:
Wiring: 1.5 mm² (AWG16), max length 5 m
Supply Voltage 24...48VDC. Absolute max. Rating 48VDC + 10%
Supply voltage for PWR Signal and PWR Motor may be different
Motor Supply GND must be externally connected to earth
Caution:
By exceeding 53VDC Power Supply Signal, the controller will go into error state, voltage higher than
55 VDC will damage the controller!
By exceeding 76 VDC Motor Supply Signal, the controller will go into error state, voltage higher than
79 VDC will damage the controller!
Do not switch Power Supply DC Voltage. All power supply switching and E-Stop breaks should be
done to the AC supply voltage of the power supplies
Power supply connectors must not be connected or disconnected while DC voltage is present.

STAT A Coding for the actual operating state
STAT B Coding for the actual operating state
The display of the various operating states is shown on the last page of this manual.
FAULT An error has occurred
(In the state ERROR a blink code of the STAT LEDs A and B tells what the actual
error is. The blink codes are explained in chapter ‘Service’of the user Manual.)
