416 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 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 while the maximum power is applied, and Brake Watts is the peak power
rating of the resistor.
Note: The maximum value was changed from 1000000.0000 to 1000000000.0000 for
firmware version 3.01.

417 Brake Watts
Sets the continuous rated power reference for the Dynamic Brake (DB). You may change
the value of this parameter only if you have selected and external DB resistor (set bit 1
“Brake Extern” of
Par 414 [Brake/Bus Cnfg].
Note: The maximum value was changed from 5000.0000 to 500000.0000 for firmware
version 3.01.

420 Pwr Strct Mode
Displays the power structure used in the drive. This is an identifier to the firmware for power structure control.
Bit 0 “Lo Pwr Strct” = PowerFlex 700S Frame 1 to 6
Bit 1 “Hi Pwr Strct” = PowerFlex 700S above Frame 6
Bit 3 “Parallel Drv” = PowerFlex 700S Frame 12
Note: Bit 3 “Parallel Drv” was added for firmware version 3.01.
421 Iqs Integ Freq
Sets the break frequency of the torque producing (q-axis) current regulator. This and Par
422 [Iqs Reg P Gain] determine the integral gain for the q-axis current regulator. Set by
the autotune procedure. Do not change this value.

424 Flux Ratio Ref
Active only in the Field Oriented Control (FOC) 2 motor control mode (when Par 485
[Motor Ctrl Mode] equals 1 - “FOC 2”). Provides a scaling factor for the flux producing
(d-axis) current reference.
•
When active ( Par 511 [FVC2 Mode Config], bit 28 “FlxRatRef Use” is set), Flux
Producing (d-axis) Current Reference = Par 488 [Flux Current] x Par 424 [Flux Ratio
Ref].
•
When inactive (Par 511 [FVC2 Mode Config], bit 28 “FlxRatRef Use” is cleared) Flux
Producing (d-axis) Current Reference = Par 488 [Flux Current] below base speed and
Flux Producing (d-axis) Current Reference = Par 488 [Flux Current] x motor base
speed/motor speed above base speed.
