FUNCTION
9802 COMMUNICATION
PROTOCOL SELECTION 0=NOT SEL/5=BACnet 0=NOT SEL Activates the external serial communication and selects the interface.
Set to 5=BACnet if integrating VFD into BACnet® system.
9902 APPLIC MACRO HVAC HVAC Pressing SAVE softkey when USER 1 LOAD is selected returns the VFD
to the parameters as shipped from RenewAire. Pressing SAVE softkey
when HVAC DEFAULT is selected returns the VFD to the ABB defaults.
9905 MOTOR NOM VOLT VFD rating Equal to Motor Voltage Must be set equal to wired motor voltage.
9906 MOTOR NOM CURR VFD rating Equal to Motor FLA Must be set equal to motor nameplate FLA. CRITICAL FOR SAFETY.
9907 MOTOR NOM FREQ 60.0 Hz 60.0 Hz Must be set 60.0 Hz
9908 MOTOR NOM SPEED Size Dependent Set per motor Usually 1750.
9909 MOTOR NOM POWER VFD rating Equal to Motor HP Must be set to Motor nameplate HP.
1001* EXT1 COMMANDS 1=DI1 1=DI1
Enables 2-wire start-stop when closing contact between 9 & 12.
(Jumper req’d between 10&11.)
1103* REF1 SEL 1=AI1 0=KEYPAD
Selects signal source for external reference REF 1.
Change to 1=AI1 for operation by an external control signal.
1104* REF1 MIN 0.0 Hz 0.0 Hz
Sets minimum value for speed reference. Used for scaling and
offsetting the input to the VFD output.
1105 REF1 MAX 60.0 Hz 60.0 Hz
Sets maximum value for speed reference. Used for scaling and
offsetting the input to the VFD output.
1201* CONST SPEED SEL 3=DI3 9=DI3,4
Enables three-speed operation at three preset speeds using two
switches between 9&13 and 9&14.
1202 CONST SPEED 1 6.0 (Hz) 30.0 Hz Determines preset speed 1.
1203 CONST SPEED 2 12.0 (Hz) 45.0 Hz Determines preset speed 2.
1204 CONST SPEED 3 18.0 (Hz) 60.0 Hz Determines preset speed 3.
1301 MINIMUM AI1 20% 20%
Sets minimum value for analog input. Used for scaling and
offsetting the input to the VFD output.
1302 MAXIMUM AI1 100% 100%
Sets maximum value for analog input. Used for scaling and
offsetting the input to the VFD output.
1304 MINIMUM AI2 20%/1% 20% Sets minimum value for analog input AI2.
1401 RELAY OUTPUT 1 1=READY 2=RUN
Energizes Relay 1 when drive is running.
Terminal 17=COM, 18=N.C., 19= N.O.
1501 AO 1 CONTENT SEL 103=OUTPUT FREQ 103=OUTPUT FREQ
Sets the Analog Output of the VFD equal to the Output Frequency
at which it is driving its Motor.
1502 AO 1 CONTENT MIN 0.0 Hz 0.0 Hz
Scales the minimum value of the analog output with respect
to the VFDs Output Frequency.
1503 AO 1 CONTENT MAX 60.0 Hz 60.0 Hz
Scales the maximum value of the analog output with respect
to the VFDs Output Frequency.
1504 MINIMUM AO 1 4.0 mA 4.0 mA Sets the minimum current for the Analog Output.
1505 MAXIMUM AO 1 20.0 mA 20.0 mA Sets the maximum current for the Analog Output.
1602* PARAMETER LOCK 1=OPEN 0=LOCKED Allows you to lock or change parameters from the keypad.
1603* PASS CODE 0 0
Entering pass code 358 allows you to change parameter 1602 once.
The entry reverts back to 0 automatically.
1607* PARAM.SAVE 0 = DONE 0 = DONE Saves parameters to permanent memory
1608* START ENABLE 1 4=DI4 1=DI1 Enables DI1 as the source of the Start Enable Signal.
1611 PARAMETER VIEW SHORT VIEW/DEFAULT LONG VIEW/DEFAULT (SHORT VIEW) Hides less commonly used parameters
2003* MAX CURRENT 1.1*I
2N
/1.8*I
2N
Typically set to 125% motor
FLA **
CRITICAL PARAMETER. Defi nes motor protection level.
2007* MINIMUM FREQ 0.0 Hz 15.0 Hz Determines minimum frequency of VFD output
2008 MAXIMUM FREQ 60.0 Hz
60.0 Hz HE units
90.0 Hz LE units****
Determines maximum frequency of VFD output
2101* START FUNCTION 1=AUTO 6=SCAN START
Selects the motor start method. SCAN START provides a
frequency-scanning fl ying start, and corrects backwards rotation.
2102 STOP FUNCTION 1=COAST 1=COAST
Sets motor to coast to a halt. Can be set to ramp down to a halt,
following the deceleration time set at 2203.
