Common Specifications
The following specifications apply to both 200 V and 400 V Class Inverters.
* 1. Rotational autotuning must be performed to ensure obtaining the specifications given for flux or open-loop vector control.
* 2. Increase the Inverter capacity if loads exceeding these current values are expected.
* 3. Only VT can be set for 200 V Class 110 kW as well as 400 V Class 220 kW and 300 kW Inverters.
* 4. The speed control accuracy depends on the installation condition and types of motor used. Contact your Yaskawa representative for details.
* 5. When connecting a Braking Resistor or Braking Resistor Unit, set L3-04 (Stall prevention selection during deceleration) to 0 (disabled). Stopping may not be
possible in the specified deceleration time if this function is not disabled.
* 6. Derating is required for applications that use repetitive loads. (Refer to page 10-6 for details.)
