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 3.001.

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 3.001.
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.
