8.2 Primary – Basic Setup Group
PRIMARY PARAMETERS
PRIMARY-1: Application Selection
Application
1)
BASIC
Default: Basic
0 - Basic
1 - Supply Fan
2 - Exhaust Fan
3 - Cooling Tower
4 - Surface/Booster
Pump
PRIMARY ‐ 1 Sets parameters based on a
specific application. Starter mode provides very
simple motor control at set speed or at preset
speeds by digital inputs.
The first step in VFD setup is an application
selection.
There are six application choices: Basic, Supply
Fan, Exhaust Fan, Cooling Tower Fan, Centrifugal
Pump and Starter.
The Basic selection provides a standard basic
VFD control with start/stop command from
keypad and mobile app interface.
The Supply or Exhaust Fan selection sets VFD
for remote BMS (Building Management System)
or PLC (Programmable Logic Controller)
Start/Stop control and 4 ‐ 20mA speed reference
signal. All other related parameters such as
Transducer range, Process Unit in WC, Direct or
Inverse PID, etc. will be automatically set to the
most common factory default values providing
accurate motor control. In some cases, extra
adjustment of some parameters is necessary to
achieve better control. Stop mode is set to Coast
mode to protect from any possible overvoltage
trips while decelerating during stop mode.
The Cooling Tower Fan selection configures
VFD for fan motor with internal inverse PID
control and feedback from a temperature
transducer. The process unit is set to °F with 0 ‐
150°F temperature transducer range and 80°F
PID set point. If MMC (Multi ‐ Motor Control)
feature is enabled with one of the auxiliary
relays, the VFD can start a spray pump based on
VFD speed and system temperature. The inverse
PID control increases fan motor speed if
temperature is above set point.
The Surface/Pump selection provides constant
pressure PID control with pressure transducer
feedback. The process unit is set to PSI with 0 ‐
100PSI transducer range and 50PSI set ‐ point.
The sleep mode is enabled and parameters are
set to optimal values, which should be
readjusted for better performance based on the
system parameters and type of pump
PRIMARY-2: Rated Motor Voltage
Motor Voltage
2) 460V Min: 200
Max: 480
Default: 460
The motor voltage rating should be checked on
the motor nameplate and set in PRIMARY ‐ 2
parameter. The VFD can produce output voltage
equal to or less than input power voltage.
PRIMARY-3: Rated Motor Horsepower
Motor Horsepower
3) 5HP Min: 1
Max: 200
Default: 5
The HP rating from the motor nameplate should
be put in this parameter. If VFD temperature
rating needs to be increased up to 122°F, de ‐
rate this parameter by 20%. The kW rating is for
230V or 415V motor with FLA close to UL table
for corresponding HP rating.
PRIMARY-4: Rated Motor Current
Motor Current
4) 0.5A Min: 0.5
Max: 55.0
Default: 0.5
The Motor Current will automatically detect
and adjust according to DC bus voltage, Line
Frequency and VFD size during initial power ‐ up.
The PRIMARY ‐ 4 parameter can be changed to
the motor nameplate FLA if different from
default.
