The PowerFlex 4 is designed so that start up is simple and efficient. The Program Group
contains the most commonly used parameters.
Smart Start-Up with Basic Program Group Parameters
= Stop drive before changing this parameter.
No. Parameter Min/Max Display/Options Default
P031 [Motor NP Volts] 20/Drive Rated Volts 1 VAC Based on Drive Rating
Set to the motor nameplate rated volts.
P032 [Motor NP Hertz] 10/240 Hz 1 Hz 60 Hz
Set to the motor nameplate rated frequency.
P033 [Motor OL Current] 0.0/(Drive Rated Amps×2) 0.1 Amps Based on Drive Rating
Set to the maximum allowable motor current.
P034 [Minimum Freq] 0.0/240.0 Hz 0.1 Hz 0.0 Hz
Sets the lowest frequency the drive will output
continuously.
P035 [Maximum Freq] 0/240 Hz 1 Hz 60 Hz
Sets the highest frequency the drive will output.
P036 [Start Source] 0/5 0 = “Keypad”
(1)
1 = “3-Wire”
2 = “2-Wire”
3 = “2-Wire Level Sensitive”
4 = “2-Wire High Speed”
5 = “RS485 (DSI) Port”
0
Sets the control scheme used to start the drive.
(1)
When active, the Reverse key is also active
unless disabled by A095 [Reverse Disable].
P037 [Stop Mode] 0/7 0 = “Ramp, Clear Fault”
(1)
1 = “Coast, Clear Fault”
(1)
2 = “DC Brake, Clear Fault”
(1)
3 = “DC Brake w/Shutoff, Clear Fault”
(1)
4 = “Ramp”
5 = “Coast”
6 = “DC Brake”
7 = “DC Brake w/Shutoff”
0
Active stop mode for all stop sources [e.g. keypad,
run forward (I/O Terminal 02), run reverse (I/O
Terminal 03), RS485 port] except as noted below.
Important: I/O Terminal 01 is always a coast to
stop input except when P036 [Start Source] is set
for “3-Wire” control. When in three wire control, I/O
Terminal 01 is controlled by P037 [Stop Mode].
(1)
Stop input also clears active fault.
P038 [Speed Reference] 0/5 0 = “Drive Potentiometer”
1 = “Internal Freq”
2 = “0-10V Input/Remote Potentiometer”
3 = “4-20mA Input”
4 = “Preset Freq 0-3”
5 = “RS485 (DSI) Port”
0
Sets the source of the speed reference to the
drive.
Important: When A051 or A052 [Digital Inx Sel] is
set to option 2, 4, 5 or 6, and the digital input is
active, A051 or A052 will override the speed
reference commanded by this parameter. Refer to
Chapter 1 of the PowerFlex 4 User Manual on CD
for details.
P039 [Accel Time 1] 0.0/600.0 Secs 0.1 Secs 10.0 Secs
Sets the rate of accel for all speed increases.
P040 [Decel Time 1] 0.1/600.0 Secs 0.1 Secs 10.0 Secs
Sets the rate of decel for all speed decreases.
P041 [Reset To Defaults] 0/1 0 = “Idle State”
1 = “Reset Defaults”
0
Resets all parameter values to factory defaults.
