Huanyang Inverter GT Series Information

[Raceman17]

I am posting this information to help others. With the help of Marty and Mikes (Fusion) posts and information It was pretty much a painless installation. I purchased a 7.5KW Huanyang GT Series Inverter from ebay with the braking resistor. I wired the acorn just as shown in the wiring diagram Mike posted in another thread. I used martys setup notes to help with setting the parameters. Some of the parameters are different because the GT series has an autotune feature. I did the autotune and it was a breeze with no issues. My motor for my spindle is a 7.5 HP 3 phase motor. It is 60HZ with a rated speed of 3465 RPM. At 230 input voltage the amps are 19.2. Below is the parameters I used on my setup. I didn't have to change any other parameters to get it to work.

P0.00 Speed Control Model (Sensorless Vector Control) =1
P0.01 Run Command Source =1
P0.03 Maximum VFD Output frequency (Varies by application) =90 (My motor is 6HZ but I am increasing the RPM by running it at 90 HZ)
P0.04 Upper Frequency limit (Varies by application - tuning)=90 (matches the P0.03 number)
P0.05 Lower Frequency Limit (Can vary by application)=0
P0.07 Frequency A Command Source (AI2)=2
P0.11 Acceleration Time (time from dead start to set speed) varies =5 (seconds)
P.012 Deceleration Time (time from at speed to stop. Use caution, without braking resistor, VFD May trip) varies= 3.9 (I am using a breaking resistor)
P1.01 Starting Frequency (can vary)=0
P2.01 Nameplate Motor Rated Power (varies based on motor used)=7.5
P2.02 nameplate Motor Rated Frequency (varies based on motor used)=60
P2.03 Nameplate Motor Rated Speed (varies based on motor used) varies=3465
P2.04 Motor Rated Voltage (varies based on motor used) varies =230
P2.05 Motor Rated Current (varies based on motor used) varies = 19.2

Autotune is ran by changing P0.16 to 1 or 2. I used 1 since I could easily remove the motor from the machine and run the autotune with no load like the manual suggested. It took about 20 seconds for the autotune.

I Changed my input #6 to SpindleOK. The attached wiring diagram has it going to input 5. My driveOK is on input 5.

Thanks again for all the help on the forum. It is much appreciated.

If you don't mind me asking, why did you get the GT series, as compared to the HY? That is, the setup you described uses V/F control, but the GT series is capable of running in vector control. V/F control will not give you optimal torque at lower frequencies. The GT drives are more expensive in comparison to the HY series, which does not offer vector control. That said, I think the price difference is only 20%.

The GT series will only do sensorless vector to (I think) 60Hz. I'm not sure on the max frequency for sensorless vector, my notes are at my shop. I fought this for quite a while and finally got an email back from Huan Yang tech support and they said SV is only for up to nominal frequency.

I really didn't pick one. I just told the ebay seller I needed one with the braking resistor and they sent me that one. Looking at the manual the gt series also does v/f control. It offers 3 different modes to set it up. This is from the manual.

This parameter is used to select the speed control mode of the inverter.
0: V/F control: It is only suitable for motor commissioning cases where needs not high
accuracy or the cases where one inverter drives multiple motors.
1: Sensorless vector control: It is only suitable for motor commissioning cases or the
cases where needs not high accuracy. This mode is applied in the universal high
performance cases where the pulse encoder is not installed or the cases where requires
high torque at Iow speed, high speed accuracy, and quicker dynamic response, such as
machine tool, injection molding machine, centrifugal machine and wire-drawing
machine,etc. One inverter only drives one motor.
2. Torque control (sensorless vector control): It is suitable for the application with Iow
accuracy torque control, such as wired-drawing.
Note:
Set right nameplate parameters of the motor and when selecting vector control
mode and complete the parameters autotune belore running to get the right motor
parameters. Only proper motor parameter can improve the high performance of
vector control.

Should I change to v/f control?

You bought a sensorless vector drive. Try it....

[Raceman17]

It is set up as sensorless vector control now.

Did you perform an autotune?

[Raceman17]

Yes. It took about 20 seconds. I did the auto tune with no load or pulley on the motor.
