AC10 Inverter
When DC bus voltage is higher than the setting value of this function, the 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%. If the braking duty ratio is
higher, the braking effect is better, but the braking resistor will get hotter
F613 Flycatching
Setting range:
0: Disabled
1: Enabled
2: Enabled the first time
Mfr’s value: 0
When F613=0, the function of Flycatching is disabled.
When F613=1, the function of Flycatching is enabled.
After inverter detects motor speed and rotating direction, the inverter will begin ramping up to
the commanded frequency, to seamlessly catch the rotating motor. This function is suitable for
situations where the inverter is auto-started after repowered on, auto-started after reset, auto-
started after the direction signal is lost while the inverter is running, and when the inverter is
auto-started after a fault. Flycatching is useful for large inertia fan loads, where drafts can
cause a fan to ‘windmill’
When F613=2, Flycatching is enabled the first time the inverter is powered on or restarted.
Note: When the control mode is set to Sensorless Vector control (F106=0), Flycatching is
disabled.
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 other situations
(inverter has no output before stop), inverter will remember setpoint frequency before it stops.
Flycatching is used for restarting a motor with a high inertia. A motor with high inertia will take
a long time to stop completely. By using Flycatching, the user does not need to wait for the
motor to come to a complete stop before restarting the inverter.
F615 Flycatching rate
Setting range: 1
~
100
Mfr’s value: 20
The Flycatching rate is used to select the rotation velocity Flycatching when the rotation
tracking restart mode is adopted. Increasing this parameter improves the speed at which the
Flycatching is accomplished. If this parameter is too large, it is likely to result in unreliable
tracking.
When F619=0, the function is not valid. When F619
≠
0, the function is valid. When
Flycatching time is longer than the setting value of F619, it will trip into FL
F619 Flycatching fault timeout period
Setting range: 0.0~3000.0S
Mfr’s value:
60.0s
