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
.
The MFDO terminal set for an alarm
[H2-01 to H2-03 = 10]
activates.
