H110 Input Phase Loss Protection Avoidance Operation (Mode selection)
If phase loss or line-to-line voltage unbalance is detected in the three-phase power supplied to
the inverter, the input phase loss protection (Lin, on Bit 1 of H98) is activated.
H110 specifies whether to avoid activating the protection by automatically decreasing the
output frequency or stop the inverter due to an alarm Lin.
- Data setting range: 0 (Disable), 1 (Enable)
H112 Voltage Shortage Avoidance Operation (Mode selection)
If the inverter output voltage level drops below the commanded value (under V/f control) due
to insufficient three-phase power, the output current may increase depending upon the load
state.
H112 specifies whether to avoid such an event by automatically decreasing the output
frequency until the inverter can output the commanded voltage.
Note: Under V/f control, decreasing the output voltage decreases the output voltage
(command value) proportionally.
- Data setting range: 0 (Disable), 1 (Enable)
H114 Automatic Deceleration (Operation level)
Settings for automatic deceleration (operation level) are detailed in the section for function
code H69.
