NOTE
2.1

Supply types

The drive is suitable for use on:
Star and Delta connected supplies
Three phase supplies with a grounded star point neutral configuration.
Three phase supplies with a line grounded delta configuration.
Ground supplies
Supplies with ground configurations TN, TN-C, and TN-S.
Floating supplies
IT supply configurations
2.2

Supply imbalance

The maximum supply imbalance: 2% negative phase sequence as per IEC 60146-1-1.
2.3

Maximum motor cable length

50m (165 ft) maximum from the motor.
2.4

Multi-motor capability

The VFD66 drive is capable of operating multiple motors at a common frequency as
long as the total current is less than or equal to the drive rating. Individual motor
protection must be provided and the output of the drive should be chain connected to
the motors. The fixed V/F mode (Pr 41 = Fd) should be used.
