System parameter group 00
PARAMETER DESCRIPTION 48
Soft-PWM carrier
function selection
1: When 00-11(P.72)<5,Soft-PWM is on(only apply to V/F
control)
2：When 00-11(P.72)＞9, if the IGBT temperature is higher
than 60°c, carrier frequency will decrease automatically,
when temperature go back to under 40°c, carrier frequency
go back to 00-11(P.72) value
0: Press STOP button and inverter stop running in PU and H2
mode
1: Press STOP button and inverter stop running in all mode.
Prevent
forward/reverse
rotation selection
0: Forward/reverse rotation are both permitted.
1: Prevent reverse rotation (Giving reverse signal decelerates
and stops the motor).
2: Prevent forward rotation (Giving forward signal decelerates
and stops the motor).
0: “PU mode”, “external mode” and “Jog mode” are
interchangeable.
1: “PU mode” and “JOG mode” are interchangeable.
3: “Communication mode” only
Second target
frequency
selection
0: Frequency set by built-in keypad
1: Frequency set by RS485 communication
2: Frequency set by analog input
Communication
mode selection
0: In communication mode, run signal and frequency is given
by communication.
1: In communication mode, run signal and frequency is given
by external signal.
Motor control
mode selection
0：Induction motor V/F control
2：Induction motor simple vector control
0: Normal Duty (ND), on fan and pump duty type.
1: Heavy Duty (HD), apply to other duties.
50Hz/60Hz switch
selection
0: Frequency related parameter default value is 60Hz.
1: Frequency related parameter default value is 50Hz.
Parameter display
mode setting
0: Parameter is displayed in “group mode”
1: Parameter is displayed in “sequence P mode”
