Table 4-4 Motor output cable sizes and connections
4.7 Motor requirements
No. of phases: 3
Maximum voltage:
400 V drive: 480 V
690 V drive: 690 V
4.8 Output short circuit protection
The drive modules are provided with fast-acting electronic short-circuit protection which limits the
fault current to typically no more than five times the rated output current and interrupts the current in
approximately 20 μs. No additional short-circuit protection devices are required. Refer to the
Unidrive M700, M701, M702 Control User Guide. CT Part Number: 0478-0353.
