Start, Stop, Direction and Speed Control

Factory default parameter values allow the drive to be controlled from

the integral keypad. No programming is required to start, stop, change

direction and control speed directly from the integral keypad.

Important: To disable reverse operation, see A095 [Reverse Disable].

Changing the Speed Reference of an IP66, NEMA/UL Type 4X rated

drive

When a Display Group parameter, for example, d001 [Output Freq] is

displayed, and P038 [Speed Ref] is set to A069 [Internal Freq], you can

change the internal frequency using the Up Arrow and Down Arrow

keys.

When the internal frequency is being adjusted, its value is displayed and

the Hertz LED flashes. Any changes are saved immediately. The display

then returns to the Display Group parameter previously shown.

TIP: By default, the speed reference of an IP66, NEMA/UL Type 4X
rated drive is set to the internal frequency, A069 [Internal Freq].

TIP: You can also change the speed reference by editing the parameter
A069 [Internal Freq] in program mode. For details on how to enter the
program mode, see the section, “Viewing and Editing Parameters.”

The default value of A069

[Internal Freq] is 0 Hz. For IP20 rated

PowerFlex 40 drives, the default value of this parameter is 60 Hz.
