Tips: Six attentions of installing VFD in automatic control system

For the frequency given signal should be used as far as possible 4-20mA international standard signal. Should make sure the signal line shield ground, to avoid the interference signal into the VFD. The production site has an interference signal, the interference signal will affect the stability of the control, so need to use input filter, and set its range to be 0.00-5.00s. If using VFD built-in PID function should use the feedback filter to increase the control stability of the built-in PID, the setting range is 0.0-60s. However, it should be noted that the filter time is set too long, the control is stable, but the system response is worse; the filter time is set too short, the system response is fast, but the control is unstable. So it should be based on the actual scene to make adjustments.
To set the corresponding manual, automatic switching operating function. Optional manual, automatic, forced manual functions of manual operator. If necessary, could also consider the redundant operation function of the current and voltage setting, that is, the VFD frequency setting signal use current setting in normal, using voltage setting in abnormal manual operation. That is, add a potentiometer for setting g the VFD frequency, so the VFD frequency reference signal has two types, current signal and voltage signal. Because there are two types of frequency setting signals input in the VFD, increasing its redundancy degree.
Must set the "overhaul switch", that is, set the "on-site overhaul switch" next to the operating equipment, when switch it to the "overhaul" position, equal to cut off the VFD running signal circuit. If someone misuse, the equipment can't run, to ensure that the safety of mechanical equipment maintainer.
Make full use of the VFD input and output control terminals function, to carry out some alarm and interlock function, to reduce wiring and improve reliability.
For single or simple control system, can take full advantage of the VFD built-in PID control function to reduce the control system equipments and reduce investment.
Some VFD have input terminals R0, T0 of control power. So should connect control power to VFD R0, T0 side in front of the main power supply. So that the VFD still has a display function after the trip, in order to analyze the cause of the malfunction and take countermeasures.

Running a single phase motor with VFD

In this video, ATO will show you details about running a single phase motor on a VFD. It's important to note that there are two wiring methods for single phase motor connecting to ATO single phase VFD: wiring of removing motor capacitor & wiring of keeping motor capacitor. At first, you should choose the wiring method you needed, and then set basic parameters step by step.

Question about GK3000-1S0037

I have two of these drives and I'm trying to run a three phase motor. Will it work or this can only do single phase in and single phase out? Thank you much.
