*1. Applicable in the sensorless vector control
*2. Applicable in the 0-Hz sensorless vector control
*3. Applicable in the 0 Hz sensorless vector control when using a motor one size smaller in capacity than the inverter
*4. The maximum frequency is set to 9.8 V for a voltage input of 0 to 10 VDC and to 19.8 mA for an current input of 4 to 20 mA,
respectively. If this causes any inconvenience, change the default datas.
*5. In the VT mode, the available functions are limited compared with the CT mode. The default data and setting range of some
functions also differ.
*6. The analog voltage and current values for the multi-function monitor output terminals show values that can only be used as a
guide for analog meter connection. The maximum output value may differ slightly from 10 V or 20 mA due to the variability of
the analog output circuit. If this causes any inconvenience, refer to AM/AMI Gain Setting on page 7-144 to adjust the default
datas.
*7. Complies with the test method specified in JIS C60068-2-6: 2010 (IEC 60068-2-6: 2007).
*8. If the altitude is higher than 1,000 m, reduce the amount of heat generation because air density decreases by 1% with the
increasing altitude by 100 m. For switching devices such as IGBTs, the amount of heat generation is proportional to the
current flowing in the device and the applied voltage. Therefore, reduce the value of the rated current by 1% with the
increasing altitude by 100 m to use a standard inverter. However, this is applicable to an altitude of 2,500 m or lower.
