* 1. The setting range depends on the setting of L8-32.
L8-32 = 1: 50°C to 130°C
L8-32 = 0: 50°C to 104°C
* 2. The factory setting depends on the Inverter capacity. The value for a 200 V Class Inverter of 0.4 kW is given.
* 3. Applicable for G7-Series Inverters with software versions PRG 1038 and later.
* 4. Applicable for G7-Series Inverters with software versions PRG 1039 and later.
* 5. If a current exceeding 110% of the Inverter rated current flows through the unit, the carrier frequency will automatically decrease and electromagnetic
noise will occur.
* 6. The lower limits are 0.4 kHz for V/f control and 1.0 kHz for flux vector control. The upper limit is the same value as that of the factory setting for L8-
39.
* 7. Applicable for G7-Series Inverters with software versions PRG 1043 and later.
