I have 3 questions regarding model H100-3S2-1B (thank you for manual in PDF format): 1) Section 5.8 F140 is labeled as Rated power of motor; section 6.8 lists F141 for rated power of motor. Should that be F140? 2) F176 (read-only) is set 0 (50Hz) but being used in USA with (60Hz) input. Is this Okay? Nameplate indicates 50/60Hz input. 3) F007 Starting Frequency of 30 has been set; however, inverter starts at 0Hz. Is there another setting that I missed? Thank you for your consideration. RR

Answer This Question

1. It can be determined that F140 is the rated power of the motor and F141 is the rated voltage of the motor. 2. Our frequency converter is applicable to the frequency of 50 or 60HZ of the input power supply, and F176 can not be set. 3. The starting frequency cannot be set so high, generally within 10HZ. It is not recommended that the customer directly set 30HZ. The frequency converter may be protected by over-current protection.

Can it control 3phase PMAC type motors?

Answer This Question

This VFD cannot drive PMAC type motors, but can only drive three-phase AC asynchronous motors.

What control terminals to use external E-Stop Button (2-Wire Circuit - interrupt=STOP)?

Answer This Question

Any terminal from X1 to X5 can be defined as stop in the parameter, so it is not fixed. For example, X4 can be defined as stop. You need to set the parameter F047 to 4, then set F001 to 1, and connect the two ends of the emergency stop button to X4 and GND.

Will this run standalone without external controls. i.e. I connect my single phase 220V to the input, connect the output to my 3 phase 220V 3HP motor and no other controls.

Answer This Question

Yes, the start and stop can be controlled through the RUN and STOP on the control panel of the inverter itself.
