Pin Definition
Pin 1: Channel 1 Analog output (0-5V)
Pin 2: GND
Pin 3: Channel 2 Analog output (0-5V)
Pin 4: GND
Pin 5: Channel 3 Analog output (0-5V)
Pin 6: GND
Pin 7: Channel 4 Analog output (0-5V)
Pin 8: GND
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
