Section VI. Function Parameter Description
65
Motor’s output frequency under rated state.
b00~b04 are the motor’s nameplate parameters which touch the
precision.Set the parameters according to the motor’s nameplate.
Excellent vector control performance requires exact motor parameters.
Exact parameters are base on the correct setting of motor’s rated
parameters.
To assure the control performance, please match the right motor as per the
inverter’s standard, motor rated currentis limited between 30%~120% of
inverter rated current.
b05: motor un-load current factory setting: (y07×40%)A
The un-load current, and affects the degree of the slip compensation
directly.
The factory value is decided by power and default value is y07×40%.
b06: stator resistor factory setting: 0.000ohm
The stator resistor, when b13 is 1,the system scales automatically.
b07: rotor resistor factory setting: 0.000ohm
The rotor resistor, when b13 is 1, the system scales automatically.
b08: leakage inductance factory setting: 0.0mH
The leakage inductance of motor’s coil winding, when b13=1, system
measures automatically.
b09: mutual inductance factory setting: 0.0mH
The mutual inductance of motor’s coil winding, when b13=1, system
measures automatically.
b05~b09 is the motor’s basic electric parameters, these parameters is
essential to achieve vector control calculation.
When b01 is set, b05~b09 would automatically reset to the defaulted
standard Y series 4 poles asynchronism motor’s parameters. Inverter could
get the motor parameters without automatic parameters setting.
If the inverter could not meet with the requirement, use b13 motor
parameters setting to get the exact motor parameter. If the right motor
parameters are available, it could be input manually.
*b10~b13: Reserved
b14: Rotate speed display plus factory setting: 100.0%
Adjust the display of motor’s actual running speed, refer to F00 monitor
select: 6 Actual motor speed.
b15: Reserved factory setting: 0
b16: Reserved factory setting: 0
b17: Reserved factory setting: 0

Section VII. Fault Diagnosis and Solutions
Problems Possible causes Solutions
Control mode setting is
wrong
Check F05.
Keyboard can
not control
Frequency setting is
wrong
Check F04.
Control mode setting is
wrong
Check F05.
Potentiometer
can’t regulate
speed
Frequency setting is
wrong
Check F04.
LED monitor indicates
error message
No voltage exists between
terminals P and N.
Check the voltage at R，S or T and charging
circuit.
U, V or W terminals
produce no output or
abnormal output.
Check the control mode and frequency
parameter. Check the terminal condition if it is
operated by an external terminal.
Re-start after powering
down or free run
Remember the set operating state.
