* 4. The speed control accuracy depends on the installation conditions and type of motor used. Contact your Yaskawa representative for details.
* 5. Derating is required for applications that use repetitive loads. (Refer to page 10-6 for details.)
* 6. A ground fault is detected if it occurs while the motor is running. Ground fault protection may not be available in the following cases.
A ground fault with low resistance which occurs in motor cables or terminals.
A ground fault occurs when the power is turned ON.
* 7. Attach a Backup Capacitor Unit for Momentary Power Loss if compensation for power interruptions of up to 2.0 seconds is required for 200 V/400 V Class
Inverters with outputs of 0.4 to 7.5 kW.
* 8. If running at a speed of 6 Hz or less, the overload protection function can operate even if running within 150% of rated output current per minute.
* 9. For the 400 V Class, there are limitations on the maximum output frequency depending on the setting of the carrier frequency and capacity.
The maximum output frequency for 400 V, 90 to 110 kW is 250 Hz. The maximum output frequency for 400 V, 132 to 300 kW is 166 Hz.
