Table 5.3 Regeneration Parameters
The Regeneration transistor turn-on and turn-off voltages are set with the motor parameters and DC bus overvoltage
level. Typically these voltages are set at follows.
Motor Voltage Bus Overvoltage Regen on Voltage Regen off Voltage
300V 400V 390V 380V
600V 800V 780V 760V
Table 5.4 Typical Regeneration Turn-on & Turn-off Voltage Levels
For drives equipped with an internal Regeneration resistor, the parameters associated with that resistor are set
automatically. If the drive has external regeneration capability only, all regeneration resistor parameters are set to
zero by default. In this case, the drive will display a fault (F3) and will not enable until suitable parameters for the
external regeneration resistors are entered and saved.
The software also checks the value of regeneration resistance entered. If too low a value is entered, such that the
current that would flow on turn-on of the regeneration transistor exceeds the ratings of the regeneration, transistor, a
fault (F3) is also reported.
