402 PWM
Frequency
Carrier frequency for the PWM output of the drive. Drive derating may occur at higher
carrier frequencies. For derating information, refer to the PowerFlex Reference Manual.
Default is dependant on power structure of the drive.
Note: This parameter was changed for firmware version 3.04 to not allow changes while
the drive is running.

403 Voltage
Class
Sets the drive configuration for high or low voltage class (I.e. a 400 or 480V ac drive).
Allows choice of configuration and affects many drive parameters including drive rated
current, voltage, power, over loads and maximum PWM carrier frequency.
Note: This parameter was changed for firmware version 3.04 to allow the
drive to produce an output voltage limited by
[Maximum
Voltage] (or maximum voltage defined by the DC bus voltage level,
[DC Bus Voltage], and DC bus voltage utilization limit,
[Bus Util Limit]).

404 Dead
Time
The time delay between turning off and turning on an upper device and a lower device in
the power structure. This parameter is set at power up and is not user adjustable.

Dead Time Comp
The amount of voltage correction used to compensate for the loss of voltage during dead
time. Do not adjust. Contact factory for alternative settings.

Power Loss Mode
Enter a value to configure the drive's response to a loss of input power, as sensed by an
input voltage below the value specified in
[Power Loss Level].
•
Enter a value of “0” to make the drive fault and coast to a stop (supply no current to the
motor) after the amount of time specified in
[Power Loss Time] has expired.
•
Enter a value of “2” to make the drive fault and continue "normal" operation after the
amount of time specified in Par 407 [Power Loss Time] has expired.
•
Enter a value of “5” to make the drive provide only motor flux current during the power
loss time.

Power Loss Time
Sets the amount of time that the drive will remain in a ride through condition before a fault
is detected.

Power Loss Level
Sets the percentage of the bus voltage at which ride-through begins and modulation
ends. When the bus voltage falls below this level and
[Power Loss Mode] is set to
0 “Coast” or 5 “Flux Only”, an alarm (F92 “Ride Thru”) will be displayed on the HIM and
the drive prepares for an automatic restart. Enter a percentage of the bus voltage derived
from the high voltage setting for the voltage class. For example: On a 400-480V drive,

Undervolts
Controls the level of bus voltage that is needed to complete precharge and sets the level
for undervoltage alarm/fault detection. Enter a percentage of the bus voltage derived from
the value in
