Basic programming information for ATV312 drive line?
Altivar ATV312 or ATV31
All models, all serial numbers
Basic Programming for the ATV312 drive.
Parameter setting Description
bFr Standard Motor frequency (50Hz or 60Hz depending on the motor and power system)
UnS Rated Motor Voltage
FrS Rated Motor Frequency (usually matches bFr)
nCr Rated Motor Current (nameplate current for the motor at the voltage it's being used)
nSP Rated Motor Speed (nameplate RPM for the motor at the frequency it's being used)
tFr Max Frequency
uFt Motor control type (defaults to n; Sensorless Vector Control, some applications work better at L; Standard V/Hz)
LSP Low Speed
HSP High Speed
ItH Motor Thermal (set to the motor nameplate current for the voltage being used, provides Overload protection) ItH should = nCr
uFr Voltage boost (usually can be left at default)
CLI Current limitation (sets peak current allowed to go to the motor. If set too low, can prevent the motor from reaching the commanded speed; display will flash off and on)
tCC 2/3 wire type (default is 2C; 2 wire control)
tCt 2 wire type (default is trn; drive must see the transition (off to on) of the run command to start the motor.) Some applications require this to be changed to LEL. Review the installation to be sure this is safe.
rrS Reverse assign (default is LI2)
When in 2C (2 wire control), LI1 is the Run Forward input.
When in 3C (3 wire control), LI1 is a Stop input, LI2 is Run Forward and LI3 is Run Reverse.
LAC= L1, L2 or L3 (default is L1, L2 and L3 enable advanced functions in the drive)
Fr1= Sets where the speed reference comes from. Default is AI1 (0-10VDC) Other options are AI2, AI3, A1U1, UPdt, UPdh, LCC, Ndb or nEt
Fr2= Sets where the secondary speed reference comes from. Active only if Reference Switching (rFC is used)
Cd1= Sets where your run command comes from. Options are [Terminal], [Local], [Remot. HMI], [Modbus], and [Com. Card]. (Parameter can be accessed if [Profile] (CHCF) = [Separate] (SEP), and [ACCESS LEVEL] (LAC) =(L3).)
CHCF= (SIM or SEP) Sets whether your run command and speed reference come from the same source or separate sources
AI1= speed pot 0-10vdc input
AI2= -10 +10vdc analog input
AI3= 4-20mA analog input
A1U1= Local speed knob on the face of the drive
UPdt= +/- Speeds
UPdh= +/- Speeds via the remove HMI
LCC= Local mode
ndb= Modbus reference
nEt= reference via network communications protocol.
