Function Parameters
9-35
AC10 Inverter
Stalling protection judging time is set by F610. When inverter starts stalling adjusting function
and continues the period of time set by F610, inverter will stop running and OL1 protection
occurs.
F611 Dynamic Braking threshold
Setting range: 200
～
1000 Subject to inverter model
F612 Dynamic braking duty ratio (%) Setting range: 0
～
100
％
Mfr’s value: 80
The starting voltage for the dynamic braking transistor is set by F611, which is in units of V.
When DC bus voltage is higher than the setting value of this function, dynamic braking starts,
braking unit starts working. After DC bus voltage is lower than the setting value, braking unit
stops working.
Dynamic braking duty ratio is set by F612, the range is 0~100%. The value is higher, the
braking effect is better, but the braking resistor will get hot.
F613 Flycatching
Setting range:
0: invalid
1: valid
2: valid at the first time
Mfr’s value: 0
When F613=0, the function of Flycatching is invalid.
When F613=1, the function of Flycatching is valid.
After inverter tracks motor speed and rotating direction, inverter will begin running according to
the tracked frequency, to start the rotating motor smoothly. This function is suitable for the
situation of auto-starting after repowered on, auto-starting after reset, auto-starting when
running command valid but direction signal lost and auto-starting when running command
invalid.
When F613=2, the function is valid at the first time after inverter is repower on.
Note: When F106=0, Flycatching function is invalid.
F614 Flycatching mode
Setting range:
0: Flycatching from frequency memory
1: Flycatching from max frequency
2: Flycatching from frequency memory and
direction memory
3: Flycatching from max frequency and
direction memory
Mfr’s value: 0
When F614 is set to 0 or 1, if memory frequency or max frequency is lower than 10.00Hz,
inverter will track speed from 10.00Hz.
If inverter is powered down, inverter will remember valid target frequency. For the other
situations (inverter has no output before stop), inverter will remember instant frequency before it
stops.
This parameter is used for starting and stopping a motor with high inertia. A motor with high
inertia will take a long time to stop completely. By setting this parameter, the user does not need
to wait for the motor to come to a complete stop before restarting the AC motor drive.
F615 Flycatching rate
Setting range: 1
～
100
Mfr’s value: 20
It is used to select the rotation velocity Flycatching when the rotation tracking restart mode is
adopted. The larger the parameter is, the faster the Flycatching is. If this parameter is too large,
its likely to result in unreliable tracking.
