Standard Inverter Specifications
9-5
* 2. When connecting a Braking Resistor or Braking Resistor Unit, set L3-04 (Stall prevention selection during deceleration) to 0 (disabled). Stopping may not be pos-
sible in the specified deceleration time if this function is not disabled.
* 3. The maximum output frequency for open-loop vector 2 control is 132 Hz.
* 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. The ground fault here is one which occurs in the motor wiring while the motor is running. A ground fault may not be detected in the following cases.
y A ground fault with low resistance which occurs in motor cables or terminals.
y 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.
