Chapter 6 - Parameter description [FU1]

FU1-15: Hold Time

FU1►	Hold Time		15	1000
15	1000 ms
Factory Default:		1000 ms		1000

To set the time to maintain holding torque at zero speed and stop the operation in a shortest time during Vector_SPD mode operation

The inverter runs to maintain speed 0 for the hold time in Vector_SPD mode and decelerates to stop after the hold time elapse.

Output Speed [Hz or Rpm]

Output Voltage [V]

Hold time

Operation method during Hold Time:

FU1-7[Stop mode] Decel: speed zero control FU1-7[Stop mode] DC-brake

FU1-16: Pre-excitation Current

FU1► Flux Force			16	1 00.0
16	100.0 %
Factory Default:		100.0 %		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.

FU1-20: Maximum Frequency

FU1-21: Base Frequency

FU1-22: Starting Frequency

FU1►	Max freq		Hz	20	60.00
20	60.00
Factory Default:		60.00 Hz			60.00
FU1►	Base freq			21	60.00
21	60.00		Hz
Factory Default:		60.00 Hz			60.00
FU1► Start freq				22	0.50
22		0.50	Hz
Factory Default:		0.50 Hz			0.50

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.
