P01.00

Start 

mode

0: Start-up   directly: start from the starting frequency P01.01

1: Start-up   after DC brake: start the motor from the starting frequency after DC brake (set   the parameter P01.03 and P01.04). It is suitable in the cases where reverse   rotation may occur to the low inertia load during starting.

2: Start-up after   speed tracing: start the rotating motor smoothly after tracking the rotation   speed and direction automatically. It is suitable in the cases where reverse   rotation may occur to the big inertia load during starting.

Note: The VFDs   above 4 kW have the function.

P01.01

Starting frequency 

of direct 

start

Starting frequency   of direct start-up means the original frequency during the VFD starting. See P01.02   for detailed information.

Setting range: 0.00–50.00   Hz

P01.02

Retention 

time of 

starting frequency

Set a proper starting frequency to increase the   torque of the VFD during starting. During the retention time of the starting   frequency, the output frequency of the VFD is the starting frequency. And   then, the VFD will run from the starting frequency to the set frequency. If   the set frequency is lower than the starting frequency, the VFD will stop   running and keep in the stand-by state. The starting frequency is not limited   in the lower limit frequency.

Setting range: 0.0–50.0s

P01.03

The brake current 

before 

starting

The VFD will carry out DC brake at the brake   current set before starting and it will speed up after the DC brake time. If   the DC brake time is set to 0, the DC brake is invalid.

The stronger the brake current, the bigger the brake   power. The DC brake current before starting means the percentage of the rated   current of the VFD.

ACC/DEC selection

The changing mode of   the frequency during start-up and running.

0: Linear type. The   output frequency increases or decreases linearly.

1: S curve. The   output frequency increases or decreases according to the S curve.

S curve is generally   used in cases where smooth startup/stop is required eg elevator, conveyor   belt, etc.

Stop 

mode

0: Decelerate to   stop: after the stop command becomes valid, the VFD decelerates to decrease   the output frequency during the set time. When the frequency decreases to P01.15,   the VFD stops.

1: Coast to stop: after   the stop command becomes valid, the VFD ceases the output immediately. And   the load coasts to stop at the mechanical inertia.

P01.09

Starting frequency

 of DC 

brake

The   starting frequency of stop brake: The VFD will carry on stop DC brake when   the frequency is arrived during the procedure of decelerating to stop.

Demagnetizing   time: Before the stop DC brake, the VFD will close output and begin to carry   on the DC brake after the waiting time. This function is used to avoid the   overcurrent fault caused by DC brake when the speed is too high.

Stop DC   brake current: the DC brake added. The stronger the current, the bigger the   DC brake effect.

The brake   time of stop brake: the retention time of DC brake. If the time is 0, the DC   brake is invalid. The VFD will stop at the set deceleration time.

Setting range of P01.09:   0.00 Hz–P00.03 (max. output frequency)

Terminal running protection when powering   on

When the running   commands are controlled by the terminal, the system will detect the state of   the running terminal during powering on.

0: The terminal   running command is invalid when powering on. Even the running command is   detected to be valid during powering on, the VFD won’t run and the system   keeps in the protection state until the running command is canceled and   enabled again.

1: The terminal   running command is valid when powering on. If the running command is detected   to be valid during powering on, the system will start the VFD automatically   after the initialization.

Note: this   function should be selected with cautions, or serious result may follow.

0: Run at   the lower-limit frequency

1: Stop

2: Hibernation 

3: Run at   zero frequency

The VFD   will coast to stop when the set frequency is lower than the lower-limit one.   If the set frequency is above the lower limit one again and it lasts for the   time set by P01.20, the VFD will come back to the running state automatically.
