PreChrg Control

Must equal 1 “Enbl PrChrg” to allow the drive to exit precharge and begin to run. Link this
parameter to a controller output word to coordinate the precharge of multiple drives.

Brake/Bus Cnfg

Configures the brake and bus operation of the drive.

• Set bit 0 [Brake Enable] to enable the operation of the internal brake transistor.

• Set bit 1 [Brake Extern] to configure the brake to use an external resistor.

• Set bit 2 [BusRef High] to select the "high" voltage setting as the turn-on point for the Bus Voltage Regulator. The "high" setting brake operation starts when

bus voltage reaches the value of Par 415 [BusReg/Brake Ref], and the Bus Voltage Regulator operation starts when bus voltage reaches the value of 415
[BusReg/Brake Ref] plus 4.5%. With the "low" setting both brake and regulator operation start when bus voltage reaches the value of 415 [BusReg/Brake
Ref].

• Set bit 3 [Bus Reg En] to enable the Bus Voltage Regulator. The output of the Bus Voltage Regulator is summed with Par 128 [Regen Power Lim] and fed

into the Power Limit Calculator. It, in effect, reduces negative torque references when the bus voltage is too high.

415

BusReg/Brake Ref

Sets the “turn-on” voltage for the bus regulator and brakes. Enter a percentage of the
high voltage setting for the voltage class. For example, on a 400-480V drive:

Brake PulseWatts

Limits the power delivered to the external Dynamic Brake (DB) resistor for one second,
without exceeding the rated element temperature. You may change the value of this
parameter only if you have selected an external DB resistor (set bit 1 [Brake Extern] of
Par 414 [Brake/Bus Cnfg]). If this rating is not available from the resistor vendor, you can
approximate it with this equation: Par 416 [Brake PulseWatts] = 75,000 x Weight, where
Weight equals the weight of the resistor wire element in pounds (not the entire weight of
the resistor). Another equation you can use is: Par 416 [Brake PulseWatts] = Time
Constant x Brake Watts; where Time Constant equals the amount of time to reach 63% of
its rated temperature the maximum power applied, and Brake Watts is the maximum
power rating of the resistor.

Brake Watts

Sets the maximum continuous power reference for the Dynamic Brake (DB). You may
