VD560 Series Inverter User Manual Parameter Description
- 107 -
Start the dc braking, generally used to make the running motor restart after stop. Pre excitation is
used to make the asynchronous motor build magnetic field first then restart, improve the response
speed.
Start the dc braking is only valid for starting mode is direct startup. The inverter dc braking will
according to the first startup dc braking current setting, start running again after start the dc braking
time. If set dc braking time is 0, then directly start without dc braking. The greater the dc braking
current, the bigger the braking force.
If the starting mode is asynchronous motor pre-excitation start, the inverter according to the first set of
pre excitation current build magnetic field beforehand, start running again after the pre excitation time
setting. If set pre excitation time is 0, then directly start without dc braking.
Start dc braking current/pre excitation current, is relative to the percentage of the frequency inverter
rated current.
F1-05 Speed Tracking Mode
0: Starting from the stop frequency
1: Starting from zero speed
2: Starting from maximum frequency
0
◎
In the shortest possible time to complete the speed tracking process, through the function of choosing
the way of frequency converter motor speed tracking code:
Zero: track down from the frequency of the power failure, usually choose this way.
1: start from zero frequency tracking upwards, in the case of power failure for a long time to start to
use.
2: the maximum frequency tracking down, general power load.
F1-06 Speed Tracking Speed 1~100 20
○
When speed tracking start again, select rotational speed of the fast track.
Parameter is larger, the faster the tracking speed. But too large can cause tracking effect is not
reliable.
F1-07 Speed Tracking Current 100%~150% 125%
◎
Speed tracking search current size.
F1-08 Stop Mode
0: Decelerate to stop
1: Coast to stop
0
○
0: decelerate to stop
After stop command effective, inverter reduced the output frequency according to deceleration time,
frequency downtime after drop to zero.
1: Coast to stop
After stop command effective, inverter stop output immediately, the motor coast to stop according to
the mechanical inertia.
