6.1 Schedule of Function Parameters 6.1 Schedule of Function Parameters
F2.12Shutdown DC braking initial frequency Setting range:0.00~20.00
Hz Default value: 0.00Hz
F2.13 Shutdown DC braking current Setting range: 0.0~100.0% Default value: 0.0%
F2.14 Shutdown DC braking time Setting range: 0.0~30.0s Default value: 0.0s
F2.12 indicates the frequency when DC braking begins to perform action during the inverter's
decelerating stop.
F2.13 indicates the percentage of output current of shutdown DC braking to the inverter's rated
output current.
F2.14 indicates a duration time for shutdown DC braking.
Oversetting of shutdown DC braking current may easily lead to
inverter tripping. DO increase the value bit by bit.
If shutdown DC braking time is set to 0.0s, there will be no DC
braking process.
F2.15 Power off restart mode selection Setting range: 0~2 Default value: 0
F2.16 Power off restart wait time Setting range: 0.0~20.0s Default value: 0.5s
0 Disabled
1 Regular start
2 Start in the mode of rotation speed tracking
This function decides whether the inverter will start running automatically or not and
the wait time for auto running in different control modes when the inverter is
electrified after power failure.
Select "0", the inverter will not run automatically when it is energized after power
failure.
Select "1", if starting criteria permits, the inverter will restart automatically at the
initial frequency in the time set by F2.15 when it is energized after power failure.
Select "2", if starting criteria permits, the inverter will restart automatically by way
of rotation speed tracking in the time set by F2.16 when it is energized after power
failure.
During the period of waiting for restarting, it is invalid to input any operating
commands. For example, the inverter will automatically abort restarting by rotation
speed tracking and restore to the status of normal stop if stop command is given
during this period.
HAZARD
If the power off restart Function (restart after instantaneous power
failure) is selected, it may cause unanticipated sudden restart
once the power switches on, which may result in heavy loss of
property, serious injury or death to personnel in some cases, eg.,
the inverter restarts due to disconnection of input power supply
undone before performing a mechanical load maintenance. DO
put a warning sign like "KEEP CLEAR" or "HAZARD" in an
eye-catching place before the equipment to avoid sudden restart
of the equipment.
F2.17 Failure self-resetting times Setting range: 0~10 Default value: 0
F2.18 Failure self-resetting interval time Setting range:0.5~25.0s Default value: 3.0s
The function of failure self-resetting indicates the failure arising from load
fluctuation or other causes can reset automatically as per set times and interval.
During the process of self-resetting, the inverter will restoreoperation by way of
rotation speed tracking and restarting. When the self-resetting times are set to "0",
self reset is disabled and failure protection should be done immediately. This function
is invalid for failure protection caused by overload or over heat.
F2.19 JOG operation frequency Setting range: 0.00~400.00Hz Default value: 10.00Hz
F2.20 JOG acceleration time Setting range: 0.1~3600.0s Default value: as per spec.
F2.21 JOG deceleration time Setting range: 0.1~3600.0s Default value: as per spec.
F2.19~F2.11 are relevant parameters set for
jogging operation, as shown in Fig. 6-6, in
which t1 indicates the actual JOG acceleration
time, t2 indicates the JOG time, t3 indicates the
actual JOG deceleration time and f1 indicates
the JOG running frequency.
