YASKAWA Varispeed G7 Inverter

Repairing of Yaskawa inverter provided also maintenance like calibration provided which is very necessary for all types of inverters as it is a Japanese inverter required regular calibration as it is very sensitive.
Parts of this inverter are also provided like capacitors ,modules, communication cables.
Efficient and with in minimum time calibration is provided.
Here is something very important i want to tell you about this inverter ( working of this inverter). when we attach a motor to its output and then give power supply to this inverter, after ready indication on, when we give run signal it starts running motor in reverse direction for some time like 10 to 15 sec then it stops motor and run it in forward direction.
                          During running in reverse direction it calculates various parameters of motor like impedance, resistance, inductance, KW  and other essential parameters.
                          And also point to be noted is that after tacking parameters of motor and running it the voltages on its output terminals where motor is attached never gives 380V or 400V in many cases because it provide volts and amperes according to requirement of motor and  its frequency.
   so never be disappointed or shocked when it runs in reverse direction.
 After first time experience of this inverter i concluded that this is a very a intelligent inverter I have ever seen.


Here are communication wiring picture of Yaskawa G& inverter 11KW attached to 21.C autocone. this wiring is very important to run machine according to ideal conditions.
