Setting
range
The parameter is just for users to view machine type and can't be changed.
1: be suitable for constant torque load of designated rated parameters
2 : be suitable for variable torque load of designated rated parameters (load of fan and pump)
Control mode of 1
P0-01
Setting
range
0: No speed Sensor vector control
The open-loop vector control is suitable for general high-performance control applications. One
frequency convertor can only drive one motor such as load of machine tools, centrifuges, wire drawing
machine, injection molding machine, etc.
1: Speed sensor vector control is a closed loop vector control. Motor-side must be installed with
encoder. The frequency convertor must be macthed with the same type of PG card with encoder. It is
suitable for high-precision speed control or torque control applications. One inverter can only drive one
motor such as load of paper-making machinery, cranes, elevators, etc.
2: V / F control is suitable for the oaccasion with less demand on load, or one frequency convertor
drives multiple motors such as fans and pumps load. It can be used for one frequency convertor to drive
multiple motors.
Prompt: motor parameter identification procedure is required when selecting vector control mode.
Only accurate motor parameters can take advantage of the vector control mode. By adjusting the
parameters of speed regulator in function code in P2 group (2 is second group), better performance can be
achieved.
Command source selection
P0-02
Setting
range
Select input channel of control command of frequency convertor.
Control commands of frequency convertor include: start, stop, forward, reverse, jog and so on.
0: Operation panel command channel ("LOCAL / REMOT" Lights off);
On the control panel, the RUN, STOP / RES keys perform running command control.
1: Terminal command channel ("LOCAL / REMOT" Lights on);
Multifunctional input terminals FWD, REV, JOG, JOG, etc., run command control.
2: Command channel ("LOCAL / REMOT" Blinking) Running command is given by the host
computer via the communication mode.
