5.8 L: Protection Functions
346 YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
• Output current is a minimum of 100% of the drive rated current and the frequency reference is less than 6 Hz.
• Output current is a minimum of 109% of the drive rated current and the frequency reference is 7 Hz or more.
When the drive switches the carrier frequency to the set value, it uses a hysteresis of 12%.
3 : Enable at Overload
The drive decreases the carrier frequency at one of these conditions:
• Output frequency is less than 6 Hz and output current is more than 120%
• Output frequency is 7 Hz or more and the IGBT temperature detected by thermistor is high

High Current Alarm
Selection
Sets the function to cause an HCA [High Current Alarm] when the output current is more than 150%
of the drive rated current.
0
(0, 1)
0 : Disabled
The drive will not detect an HCA.
1 : Enabled
If the output current is more than 150% of the drive rated current, the drive will detect an HCA.
