NOTE
High-impedance isolation in the relation to device ground
If excessively high currents flow via the earth terminals, high-impedance
isolation from the device ground is possible. In some circumstances this can
result in the malfunction of the drive. To prevent this situation arising, avoid
currents circulating in the wiring.
NOTE:
Take into account that in the event of a fault, the Power Supply Unit may no
longer be able to feed regenerative energy from the DC-AC Servo Drive to
the mains. To prevent irreparable damage to the Power Supply Unit's braking
resistor on extended regenerative operation, the DC-AC Servo Drives and the
Power Supply Unit can be mutually interlocked via terminal X4. You will find
further information and an example circuit in
chapter 10.1, page 85 .
