Why do Android mobile devices support a USB-On-the-Go (OTG) connection between DriveWizard Mobile and the Yaskawa drive, but Apple iOS devices do not?

Wired connections between DriveWizard Mobile and the Yaskawa AC drive require mobile devices support USB -OTG. Most Android mobile devices include USB-OTG, however Apple mobile devices do not; therefore, the only way Apple devices can communicate with Yaskawa drive is via Bluetooth, which requires the optional Bluetooth version of the keypad. Android mobile devices support both methods (cable connection and Bluetooth).

What is a "Multi-Function Digital Input"?

The functions for digital inputs can be changed to suit application requirements. The most common functions are chosen as factory defaults and pre-programmed into the drive..Settings for these type of inputs are referred to as, "Multi-Function". Normally (i.e., at factory settings), an auxiliary frequency reference has already been set, although gain, bias, or preset speed can be chosen by the user.

What is 2-Wire Control and 3-Wire Control?

These are the names of common methods that determine how the drive Run/Stop function is controlled. In 2-Wire Control, a maintained contact closure causes the drive to run. When this same contact is opened, the drive will stop. In 3-Wire Control, a momentary contact closure causes the drive to run. The drive runs until a separate, normally closed contact, is momentarily opened.

What happens if the STOP button on the Digital Operator is pressed, while the drive is being controlled remotely by START/STOP circuitry connected to the drives I/O terminal block? Can the drive be restarted locally?

When the drive is stopped locally while running in two-wire control, the remote run command is never actually removed. This means there is a continuous remote run command that has been overridden by the Digital Operator stop command. In order to restart the drive, one of two things can be done. Either the main 230/480V drive input power can be cycled, or the remote run command can be removed and then reapplied.

There is an alternative, if cycling drive power or toggling the remote run is undesirable in the case above.

A recommended solution would be to install a local STOP switch at the drive, Install the normally closed STOP switch in series with the remote run contact and the two-wire start/stop terminal located on the drive. This way the drive can be stopped locally, and the run contact can be removed and reapplied right at the drive.

What does it mean when the drive has a RUN command and the STOP light is flashing on the drive display?

If the 'Stop' LED is flashing and the 'Drive' light is on, the drive is receiving a run command, but has either no frequency or a zero (0) frequency reference.

What are the concerns when operating a motor with a AC drive rated for less output voltage than the motor namplate . Example: The AC drive rating is 480 VAC and the motor is 600VAC.

This is not recommended. Essentially, the motor needs a specific proportion of voltage to frequency to product rated torque. The motor will not be able to provide the torque that it should, because it is drawing more current to make up the lack of voltage. The motor will be unable to deliver it's rated power (kW).

How does electronic thermal (motor protection) work?

The motor heat characteristics are simulated by observing the motor current and operating frequency data. The motor is protected from overheating within its entire speed range. The motor characteristics differ by motor type, thus it is necessary adjust the inverter programming for the appropriate motor type, i.e., standard motors or inverter-duty motors. When dealing with multiple motors connected to one drive, a thermal relay is required for each individual motor. Most Yaskawa drives contain a UL approved motor overload protection such as Class 20. Refer to the specific Drive specifications for details.

Can the brake coil of a brake-motor be put directly across the motor winding when the motor is run by a VFD?

No, a brake coil should not be connected to the motor terminals of the AC drive.. Although this was common practice when the motor was controlled by an electro-mechanical contactor or disconnect from the power line, it will not work with a variable frequency drive (VFD). Not only will the brake coil cause excessive load on the VFD output, but the brake coil may burn up or not energize at all because the VFD output is variable voltage and variable frequency and is tailored to the motor, not the brake.

Can I control Start/Stop of my drive by just applying and removing input power?

No. You never want to control Start/Stop of the motor by applying and cutting power to the inverter. This will stress the input diodes, precharge resistor and precharge contactor of the inverter and eventually cause failure.

Are common multimeters able to measure the correct output voltage of the VFD?

An inverter provides a PWM output voltage waveform. Most digital multimeters (DMM) measure the peak voltage and calculate the average. In order to obtain an accurate output voltage reading a "true RMS" meter with selectable low pass filter is needed. Other reliable and accurate instruments include an oscilloscope.
Many true RMS meters display readings 20 to 30% higher than the drive's controller display as most of true RMS digital multimeters have wide bandwidth. These multimeters are measuring the carrier frequency/switching frequency generated by VFDs. The low pass filter (LPF) is designed to help block unwanted voltages above 1 kHz when measuring AC voltage or AC frequency. The LPF can improve measurement performance on composite sine waves that are typically generated by inverters and variable frequency motor drives. Please see the attached for additional support links.
