Operation Keypad
The mode button is used to program the drive via various parameters, view parameters and store
parameter settings.
The DISPL/RESET button is used to cycle through the operational values (Status Display) of the drive.
This button will also reset the drive when a fault has occurred. It can also be used to return to the
main display screen at any time during navigation.
The RUN/STOP button is used to start or stop drive operation.
The Up and Down buttons are used to scroll through the parameter groups, sub-groups and to change
parameter values. A single press of the Up or Down button will change the parameter settings in single-
unit increments. Holding the Up or Down button will quickly run through the range of values.
The potentiometer can be used to adjust the drive operation frequency, changing the speed of the motor.
Function Keys
The operation keypad includes an LED display, 4 LED
indicators, 6 function keys, and a potentiometer. The
diagram below shows all the features of the digital keypad
and an overview of their functions.

Status Display
The Status Display shows the operation values and parameter settings of the SIMVFD. The display also has four LED
Indicators that show the RUN, STOP, FWD, and REV status of the drive.
Displaying the Drive Status
Press the DISPL/RESET button on the keypad repeatedly to cycle through the status messages on the SIMVFD. The
diagram below shows the order of the status messages and their definitions. The diagram below shows the order of the
status messages and their definitions. The status of the drive can be shown in RUN or STOP mode.

Programming the SIMVFD
The SIMVFD parameters are divided into 4 groups to simplify navigation.
These groups are further divided into sub-groups for the individual parameter settings within each main parameter group.
When the MODE button is pressed, the drive enters Program mode where the user can then use the UP/DOWN keys to
cycle through the available parameter groups.
Pressing the DISPL/ RESET at any time navigates back to the main parameter group.
The drive can only enter Program mode when it is in Stop mode (not running).
Parameter Groups and Settings Navigation - 1
NOTE: When user clicks on the MODE button and enters programming mode, the REV and RUN/STOP buttons are
disabled. Upon exit of Program Mode, the buttons become fully functional again and user is returned to the Output
Frequency display

Parameter Groups and Settings Navigation - 2
NOTE: Pressing the DISPL/RESET button at any time backs out 1 mode level.
If pressed while at the parameter level, user is backed out to the sub-group level. If in a sub group, user is backed out to
the Main Group Level. (Repeated pressing of the DISPL/RESET button will bring user back to the default display and then
start cycling through status displays).

SIMVFD Parameter Details
Motor Parameters
0-0 Motor Nameplate Voltage
Range: 208, 230, 400, 460, 575
Default Setting: 208
This parameter determines the Maximum Output Voltage of the drive.
The Maximum Output Voltage setting must be less than or equal to the rated voltage of the motor as indicated on
the motor nameplate.
0-1 Motor Nameplate Amps
Range: 3.80, 5.12, 6.10, 13.40, 18.00, 21.00
Default Setting: 3.80
This parameter sets the output current to the motor. The value is determined by the value found on the motor nameplate.
0-2 Motor Base Frequency
Range: 50/60
Default Setting: 60
This parameter setting is determined by the motor nameplate data.
0-3 Motor Base RPM
Range: 800, 970, 1155, 1450, 1725, 2000
Default Setting: 800
This parameter setting is determined by the motor nameplate data.
0-4 Motor Maximum RPM
Range: P0-3 to 2000 rpm
Default Setting: P0-3
This parameter setting is determined by the needs of the application, but should not exceed the maximum RPM
rating of the motor being used.

Ramp Parameters
1-0 Stop Method
Range: 0: Coast to Stop, 1: Ramp to Stop
Default Setting: 0
This parameter determines how the motor is stopped when the drive receives a Stop command.
Coast: The drive stops output instantly upon command, and the motor free runs until it comes to a complete stop.
Ramp: The drive decelerates the motor to zero speed according to the deceleration time set in parameter 1-2.
1-1 Acceleration Time
Range: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 40 sec
Default Setting: 10
This parameter is used to determine the rate of acceleration for the drive to reach Maximum Motor RPM (0-4). The
rate is linear unless Acceleration S-Curve (1-3) is “Enabled.”
1-2 Deceleration Time
Range: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 40 sec
Default Setting: 10
If Ramp is selected in 1-0, this parameter governs the time the drive output reduces to 0Hz when a Stop, Fault
(external or internal) is received. The rate is linear unless Deceleration S-Curve (1-4) is “Enabled.” If deceleration
time is set to low (fast deceleration), motor regeneration could cause a DC Bus Overvoltage Fault. If this occurs,
increase the deceleration time.
1-3 Acceleration S-curve
Range: 1 to 5
Default Setting: 0
