V260 Series High Performance Closed-Loop Vector Inverter User Manual
7.11 VECTOR RUNNING PARAMETERS (MOTOR 1) (GROUP F2.0)
F2.0.00~F2.0.04 Motor rated parameters
——
Factory default:
☆
Nameplate parameters of asynchronous motor, for ensure performance control, it must:
y
Correctly set nameplate parameters;
y
Power level of motor and frequency inverter shall be match with each other, generally motor only can be
two levels less or one level more than frequency inverter.
Change the rated power setting (F2.0.00), it may match with later parameters automatically. Please change
the settings in order.
Any one of the nameplate parameters changed, frequency inverter can set static identification of motor
parameters once automatically. With motor accessed to start running, an additional static identification of
parameters will be conducted prior to running (parameter FF.4.43 can shield this function).
F2.0.05 ~ F2.0.09 Motor internal parameters
—
Factory default:
☆
This group of parameters can be auto updated after parameter identification, generally free of necessity of
setting.
F2.0.10 Slip compensation coefficient
Setting range: 0.50~1.50
Factory default: 1.00
Slip compensation coefficient is used for slip frequency calculation, valid with vector control mode. With SVC
running, this parameter can be amended to adjust speed for compensation control.
F2.0.24 Z pulse initial angle
Setting range: 0.0~359.9
Factory default: 0.0
This parameter is valid when Z pulse selection is valid ([F8.0.07] = 1), used for set corresponding mechanical
rotating angle of Z pulse position.
F2.0.25 Overload protection
setting motor1
Setting range: 50.0~131.0%
Factory default: 110.0
With dragging rated current value ( parameter F2.0.02, F2.1.28) of motor, frequency inverter can
automatically confirm the heat protection curve of motor. This parameter is used for setting sensitivity of heat
relay protection to load motor of frequency inverter. The larger the value is, the lower the sensitivity is. Please
set according to the actual load capacity of motor.
When fixed value of this parameter is 131.0%, overload protection function of motor closes.
¾
When a frequency inverter runs with several motors in parallel, function of heat relay
protection of frequency inverter will out of action automatically. In order to protect motor
efficiently, it is suggested that installation of heat protection relay in each motor.
