Goodrive880 Series Regenerative Rectifier Unit Hardware Manual
A.1 Capacity
Choose a regenerative rectifier model based on the rated current and power of the motor. To endure the
rated power of the motor, the rated output current of the regenerative rectifier must be larger or equal to
the rated current of the motor. The rated power of the regenerative rectifier must be higher or equal to that
of the motor.
Note:
The maximum allowable shaft power of the motor is limited to 1.5 times the rated power of the motor. If

the limit is exceeded, the regenerative rectifier automatically restricts the torque and current of the
motor. This function effectively protects the input shaft against overload.
The rated capacity is the capacity at the ambient temperature of 40°C.

You need to check and ensure that the power flowing through the common DC connection in the

common DC system does not exceed the rated power of the motor.
A.2 Grid specifications
AC 3PH 380V(-15%) – 440V(+10%)
Grid voltage
AC 3PH 520V(-15%) – 690V(+10%)
According to the definition of IEC61439-1, the short-circuit capacity indicates the
apparent power during 3PH short circuit when the power system is in the specified
running mode, the size of which is equal to the product of the short-circuit current and
Short-circuit the rated voltage at the short-circuit. According to the short-circuit current

capacity

requirement, the maximum allowable short-circuit current at the incoming end is
100kA. Therefore, the product is applicable to scenarios where the transmitted current
in the circuit is no larger than 100kA when the rectifier runs at the maximum rated
voltage.
Frequency 50/60Hz±5%, with a maximum change rate of 20%/s
