becomes longer than the set deceleration time.
◆In case of F14 set value : 3.
The output frequency is lowered by the control by
which the DC voltage of the main circuit is kept
constant from the regeneration energy, so that the
inverter may continue operation when momentary
power failure occurs.
The response is adjusted with U23 and U24 at this
time.

Input phase loss protection U48
◆This function selects operation of input phase loss or
power supply unbalance protection.

When "2" is set to U48, protection
operation of the inverter to input phase
loss or power supply voltage unbalance
does not work. If you use it as it is,
there is a possibility of damaging an
inverter and
failure may result.
RS-485 protocol selection U49

◆When function code F13 (electronic thermal)is set to 2,
both the type of the braking resistor and connection
circuit are set. Factory setting is set to nominal applied
resistor and the number of resistor is one. When the
power load capacities of resistor are increased, set the
factory setting properly
