Q: At the base block Yaskawa inverter is what reason?: Garbage in Yaskawa signal board on the small line contact oxidation, look good, this is a kind of weak signal, and for safety relay is not the safety loop at high levels in a small line short circuit, 1000 Yaskawa A factory is shorted for a long time have blocked the oxidation base

Q: When the inverter is running at full 50HZ, the output voltage decreases and the output current becomes smaller. What is the reason?: I don't know if you're a manufacturer of car gearboxes, and we've also done car engine tests. The operation in the 50HZ when the inverter is not reduced voltage, if only a little decrease will decrease, this is due to increasing frequency, controllable silicon resistance increases, the corresponding motor voltage decreased slightly, not what the essence of influence.

Q: What is the difference between frequency converter and servo driver?: The general use of the situation, such as high-speed, high-precision positioning equipment, servo, high power speed control using frequency conversion.Like the central air conditioning system, elevators and so on, many places use frequency conversion; like the textile machine, the placement machine, the plug-in machine uses the servo. In fact, many cases are used in conjunction with the two systems, according to the needs of the design arrangements.

Q: Not to say that the inverter speed is mainly down frequency, how can I see the frequency rise to 60HZ, so that the three-phase motor is not more than the rated speed?: Frequency rising problem of frequency converter;Voltage matching; the rated voltage of the converter is in line with the rated voltage of the load.Current matching; ordinary centrifugal pump, the rated current of the converter is in line with the rated current of the motor. For special loads, such as deep water pumps, it is necessary to refer to the motor performance parameters and determine the current and overload capacity of the inverter with maximum current.Torque matching; this situation may occur when a constant torque load or a deceleration device.

Q: What is the function of a frequency converter on an electric motor?: Mainly for AC motor speed regulation, but also is a smooth stepless speed regulation. You can also implement some specific controls.

Q: Check the fault information is the power supply voltage instability, but other inverters are running well, what is the matter? Will there be any other parameters are not set correctly, thank you!: This example is obvious, due to undervoltage, to find the problem of power, the first to exclude external problems, from the inverter inside to find the reasons.

Q: How do you understand the ramp up (descent) time of the inverter? Thank you!: The ramp up time is to start from the 0 speed, inverter, running to reach the given speed (for example: 1420) the time required, in general, the longer the time, the frequency converter and motor impact is small. In the actual work process, according to process requirements to set the length of time. (more than 10-15 seconds) or so, if it is a pump or fan motor, do not need to change its rise time, the default can.

Q: Ask, what is the ratio of frequency converter?: Connect the air switch, the power supply, check the wiring is correct, close the air switch, turn on the frequency converter, and the digital tube shows 0.Turn off the power, the power indicator light is extinguished, then connect the motor, on-off switch, tone potentiometer, trimmer potentiometer, inching button, frequency meter (0 ~ 10V voltage meter), three sets of inverter and motor proportion of joint operation, the inverter and the motor grounding terminal reliable grounding, and carefully check.

Q: What does Ro1c mean on a converter?: RO1C is the common terminal and the RO1A is normally closed, and the RO1B is normally open. The set of contacts is the output signal that is ready to run. That is, the self-test of the converter is completed and the output signal of the relay can be operated.

Q: If you don't plug in the PG card, do you use PLC's PID control?Plug in the PG card and the PLC PID control, which is reliable and precise?: Mainly depends on what you want closed loopIf it is speed closed-loop, with PLC, you can not use PG card, direct PLC acquisition speed as a negative feedback signalIf it is a closed loop of ordinary process variables, such as pressure, temperature, etc.Neither PLC nor PG cards are requiredThe PG card is mainly used in the speed closed loop of the converter to collect signals
