PowerFlex 520-Series Adjustable Frequency AC Drive

Advanced Program Group Parameters

See the PowerFlex 520-Series Adjustable Frequency AC Drive User Manual, publication
descriptions of the parameters listed here, as well as the full list of available parameters.
= Stop drive before changing this parameter.
= Parameter is specific to PowerFlex 525 drives only.
PF 525
No. Parameter
A410... [Preset Freq x]
A417
Sets the frequency of the drive outputs to the programmed value when selected.
A418...
A425
PF 525
A426 [Keypad Freq]
Provides the drive frequency command using the built-in keypad navigation. When P047, P049 or P051
[Speed Referencex] selects 2 "Keypad Freq", the value set in this parameter controls the frequency of the
drive. The value of this parameter can also be changed when navigating with the keypad by pressing the
Up or Down arrow keys.
A427 [MOP Freq]
Provides the drive frequency command using the built-in Motor Operated Potentiometer (MOP).
Important: Frequency is not written to non-volatile storage until drive is powered-down. If both MOP Up
and MOP Down are applied at the same time, the inputs are ignored and the frequency is unchanged.
A428 [MOP Reset Sel]
Determines if the current MOP reference command is saved on power down.
A429 [MOP Preload]
Determines the operation of the MOP function.
A430 [MOP Time]
Sets the rate of change of the MOP reference.
A431 [Jog Frequency]
Sets the output frequency when a jog command is issued.
A432 [Jog Accel/Decel]
Sets the acceleration and deceleration time used when in jog mode.
A433 [Purge Frequency]
Provides a fixed frequency command value when t062, t063, t065-t068 [DigIn TermBlk xx] is set to 40
"Purge".
A434 [DC Brake Time]
Sets the length of time that DC brake current is "injected" into the motor.
A435 [DC Brake Level]
Defines the maximum DC brake current, in amps, applied to the motor when P045 [Stop Mode] is set to
either 4 "Ramp" or 6 "DC Brake".
ATTENTION: If a hazard of injury due to movement of equipment or material exists, an auxiliary
mechanical braking device must be used. This feature should not be used with synchronous motors.
Motors may be demagnetized during braking.
A436 [DC Brk Time@Strt]
Sets the length of time that DC brake current is "injected" into the motor after a valid start command is
received.
A437 [DB Resistor Sel]
Enables/disables external dynamic braking and selects the level of resistor protection.
