Step 6. (Optional) Rescale bus voltage range

The default voltage levels are:

Over voltage trip = 63.2 V

Under voltage trip = 18.4 V

Dynamic brake voltage = 58.7V

If a different voltage range is desired, the user can modify hardware (resistors) to obtain a different voltage range.

Resistors R31 and R43 (R31 = R43) can be replaced to accommodate a different voltage range.

Over voltage trip = 402 / R31 * 5 * 3360 / 4095 volts

(must not exceed 70 Volts)

Under voltage trip = 402 / R31 * 5 * 976 / 4095 volts

(must be above 15 Volts)

Dynamic brake voltage = 402 / R31 * 5 * 3120 / 4095 volts

After determining the value of R31 (R43 = R31), the dc bus scaling in the Excel Spreadsheet (drive commissioning

tool) need to be updated by the following equation:

Dc bus scale = R31 * 4095 / (5 * 402) where R31 is in Kohm.
