FU1-15: Hold Time

FU1? Hold Time
15 1000 ms
Factory Default:
1000 ms
To set the time to maintain holding torque at zero speed
and stop the operation in a shortest time during
Vector_SPD mode operation
l The inverter runs to maintain speed 0 for the hold
time in Vector_SPD mode and decelerates to stop
after the hold time elapse.

à Operation method during Hold Time:
FU1-7 [Stop mode] Decel: zero speed control
FU1-7 [Stop mode] DC-brake

FU1-16: Pre-excitation Current

FU1? Flux Force
16 100.0 %
Factory Default:
100.0 %
FU1-16 [Pre-excitation Current] is applied during FU1-14.
When the motor magnetic flux increases to match the
rated magnetic flux, pre-excitation current starts to
decrease. When the motor magnetic flux reaches to the
rated magnetic flux, the pre-excitation current matches
the rated pre-excitation current.

FU1? Max freq
20 60.00 Hz
Factory Default:
60.00 Hz
FU1? Base freq
21 60.00 Hz
Factory Default:
60.00 Hz
FU1? Start freq

FU1-20 [Maximum Frequency] is the maximum output
frequency of the inverter. Make sure this maximum
frequency does not exceed the rated speed of the motor.
FU1-21 [Base Frequency] is the frequency where the
inverter outputs its rated voltage. In case of using a
50Hz motor, set this to 50Hz.
FU1-22 [Starting Frequency] is the frequency where the
inverter starts to output its voltage.
