Setting Operating Parameters
Enter Required Parameters Before Starting VFD
1.
Application [SET–00]:
Use the keypad to select the type of application the drive will
control. When a selection has been made, application related parameters will be auto
-
matically updated to proper defaults. Enter the following parameters to ensure best per
-
formance for the specific installation.
NOTE:
The
BASIC
application provides standard VFD control with start/stop command
from keypad and speed reference from a remote analog signal. For systems using a trans
-
ducer or other control sensors, choose the relevant motor type to ensure that correct
defaults are set.
NOTE:
When using a
MagForce
or other permanent magnet motor application, refer to
“Operation with Permanent Magnet Motors” on page 79
2.
Input Phase [SET–01]:
Verify that the setting matches the type of power supply— 3-
phase (default).
3.
Motor Horsepower [SET–02]:
Enter the rated horsepower from the motor nameplate.
4.
Motor FLA (SFA) [SET–03]:
Enter the FLA (Full Load Amps) rating from the motor
nameplate; or, enter SFA (Service Factor Amps) if using a submersible pump motor.
5.
Motor RPM [SET–04]:
Enter the rated motor RPM from the motor nameplate.
6.
Motor Voltage [SET–05]:
Enter the rated voltage from the motor nameplate.
Verify Default Settings
After the initial parameters have been entered, the following default settings should be checked and
adjusted to ensure expected operation. Refer to the
“Default Settings Tables” on page 50
for a list of auto
-
matically populated settings per application.
1.
VFD Max Freq [VFD–00]:
The highest frequency (speed) allowable. If running a MagForce pump, this
should be set to the calculated electrical frequency corresponding to the target pump RPM. Refer to
“Setup MagForce Pump Motor” on page 80
2.
VFD Base Freq [VFD–02]:
This should be set to the motor nameplate frequency rating.
3.
Auto Speed Ref [SET–07]:
Select the source of frequency (speed) setpoint the drive will use when in
Auto mode.
•
When using one of the analog inputs with an automated BAS, BMS, or PLC system, be sure to con
-
figure the terminal for the correct impedance. Refer to
“Terminal Identification” on page 41
•
When using feedback from an analog sensor, such as a transducer, select PID Output. When PID
mode is selected, additional parameters must be verified for setpoints, inputs, and limits.
•
When set to Keypad, the drive will run at the Keypad Speed Reference (F on display).
4.
Auto Run Command [SET–08]:
Select the source of RUN command when VFD is in Auto Mode—Key
-
pad or external.
5.
Hand Speed Ref [SET–09]:
Select the source of frequency (speed) setpoint the drive will use when in
Hand mode. PID is disabled in Hand mode. Be sure to configure any selected input terminals for the
correct impedance.
•
When set to Keypad, the drive will run at the Keypad Speed Reference (F on display).
6.
Hand Run Command [SET–10]:
Select the source of RUN command when VFD is in Hand Mode—Key
-
pad or external.
7.
Acceleration Time [SET–11]:
Enter a time in seconds for drive to ramp up from stop to maximum fre
-
quency. Recommended defaults are 2 seconds for submersible pump motors and 20 seconds for most
other applications. Additional acceleration curves can be added for more precise control through
selected frequency ranges. Refer to
“Acceleration/Deceleration Control” on page 71
