3.1 Ratings
3.1.1 Drive output current ratings
For drive output current ratings please refer to the Unidrive SP User Guide.
3.1.2 Low Voltage DC rating
On all but size 1, the applied Low Voltage DC supply level is set by the user in Pr 6.46.
On the size 1 drive this value is non adjustable. The value set by the user will be within
limits as detailed below.
The default setting is 48V for all the drive sizes. The over voltage trip threshold and braking
IGBT turn on voltage are scaled from this value as follows :
• Brake IGBT turn on = 1.325 x Pr 6.46 (V)
• Over voltage trip = 1.45 x Pr 6.46 (V)
Table 3-1 Low Voltage DC drive rating
Minimum and maximum voltage values include ripple and noise. Ripple and noise levels
must not exceed 5%.
Minimum start up voltage
This is the minimum voltage that is required to initially start up the drive.
Maximum braking IGBT turn on voltage
This is the voltage level that the drive braking IGBT will turn on.
Maximum over voltage trip threshold
This is the voltage level that the drive will trip OV. (Over Voltage).
The maximum supply voltage is governed by the 0V trip level and brake turn-on level.
The drive may be supplied with a greater voltage than the nominal continuous operating
voltage, providing there is suitable headroom between the applied DC voltage and the
brake IGBT turn-on voltage and that regen energy has been taken into account.
