General Precautions
1. The drive should generally be at least two model/capacity sizes larger than the motor.
2. Use only devices designed specifically for operation with a PWM drive.
3. For operation in Open Loop Vector Control for PM motors, contact Yaskawa.
4. When operating a PM motor at high frequency, an AC reactor should be installed between the motor and drive to reduce drive and motor heating.

Torque Compensation
High speed motors typically have very low impedance compared to standard 60/120 Hz motors. These high speed/low impedance motors saturate easily and may cause hunting and oscillation when a high V/f pattern is applied, especially at high frequencies. Therefore, consider decreasing torque compensation gain according to the output frequency as shown in
.

On-Delay Compensation
High speed motors typically operate at low V/f ratios compared to standard 60/120 Hz motors, and On-Delay
Compensation settings may adversely affect the motor voltage and cause hunting and oscillation. By reducing voltage level for On Delay Compensation according to the output frequency, the user can have On Delay Compensation be active only during low frequencies as shown in

Using an Output Reactor
If drive oL2 faults occur and a typical drive overload is not suspected, an output reactor or a larger drive may be required to eliminate oL2 faults. High-speed motors typically have very low impedance, which may result in excessive peak motor current, increased motor temperature, low speed cogging, or increased torque ripple.
It may be necessary to use an output reactor to add impedance to the system and reduce the peak ripple current and eliminate nuisance oL2 faults. To confirm that excessive peak current caused by low motor impedance is causing the oL2 fault, measure the output current using an oscilloscope or chart recorder with a clamp-on amp meter.
Generally, the peak of the motor current waveform should not exceed 100% continuous drive HD nameplate x 2.5
. This
When using a reactor to reduce peak current, consult with the reactor manufacturer to select a reactor that will smooth out the current waveform and also prevent a large voltage drop.
Proper reactor selection is critical in high speed applications because the reactor impedance is directly proportional to the output frequency, which is usually given at 60 Hz. Example; a reactor operating at 600 Hz will have 10 times the impedance and result in 10 times the voltage drop when compared to the same reactor operating at 60 Hz.
Using a larger capacity drive to allow for the additional peak current may also solve the oL2 overload trip problem. The decision to employ an output reactor or increase drive capacity is made on a case-by-case basis.
Figure 3
Figure 3 Measuring Peak Current
Fine Tuning the Carrier Frequency
It is important to optimize the carrier frequency to improve the motor current waveform. This will improve motor speed stability and torque performance and also limit hunting and oscillation at higher speeds.
Use one of the following setting recommendations to fine tune the carrier frequency for optimum motor performance:
1.
For a flat 7.0 kHz across the speed range: Set C6-02 = “F” with C6-03 = “7.0”, C6-04 = “7.0”, and C6-05 = “0”. The
7.0 kHz across the output frequency range keeps the carrier frequency as high as possible.
2.
To create a ramped carrier frequency pattern to keep the output frequency and carrier frequency at a constant ratio:
• Set C6-02 = “F” to build a custom pattern.
• Set C6-03 = “7.0 kHz” so the motor will run at 7.0 kHz at top speed.
• Set C6-04 = “1.0 kHz” so the carrier frequency will be ramped for the greatest output frequency range.
• Solve the following formula for C6-05:
C6-05 = [7000 Hz / (2 x E1-04)]
14 YASKAWA TM.A1000SW.056 YASKAWA AC Drive - A1000 Custom Software Supplement
6 Application Notes
The C6-05 setting range is 7 ~ 99, however a setting lower than 7 disables the ramp function and C6-03 is used across the output frequency range. For motors with output frequencies greater than 500 Hz, use C6-05 = 7.
• Solve for corner output frequencies A and B

Precautions for High Frequency/Low Impedance Motors
High frequency motors exhibit different characteristics than standard 60/120 Hz maximum frequency motors. The low impedance associated with these high frequency motors often requires manually programming a custom V/f pattern into the E1 parameter group to obtain proper performance and rated power from the drive-motor combination.
The low impedance may also cause excessive motor current. In addition to considering the use of an output reactor, it may be advantageous to oversize the drive to accommodate the high peak current that may result from the low impedance motor. Using a drive that is at least one or two models larger than the motor FLA may also help eliminate the oL2 faults.
Compatibility between the drive, motor, and the reactor is best accomplished via testing and observation of the motor current waveform with an oscilloscope.
Refer to Using an Output Reactor on page 14
.
Precautions for Auto-Tuning Open Loop vector for PM motors
For SPM motors with a small difference in d-axis inductance (E5-06) and q-axis (E5-07) inductance, parameter S1-02 should be disabled* (S1-02 = 0, default = 1) prior to performing Auto-Tuning. In motors where there is some difference in d-axis inductance (E5-06) and q-axis inductance (E5-07), reduce the setting of n8-84 prior to Auto-Tuning if there is a relatively lower amount of motor armature resistance (E5-05).
* If S1-02 = 0 (disabled), the drive will use saliency during Auto-Tuning and not estimate motor polarity.
Note: Because a high frequency motor has a unique design, Auto-Tuning may not be sufficient for the drive to achieve proper motor performance. Motor parameters (E5-XX) should be set manually accordingly the information on the motor nameplate.
Switching the Scan Frequency per Cycle (S1-03)
Normally there is no need to change S1-03 from the default setting.I f there is a problem with output voltage weakening when attempting to compensate for output current distortion as the motor reaches 1000 Hz, with the load decoupled from the motor, then try setting S1-03 = 1. If this fails to solve the problem, then install an AC reactor designed specifically for
AC drive high frequency applications.
