79
This parameter defines the action delay time of magnetic control conductor
when it’s from power source to variable frequency or from variable frequency to
power source.
F3.25 Automatic switchover interval Range: 0000－9999 0000
By setting this parameter, can achieve the function of rust-proof die of the
motor, the inverter can delay time by it and then automatically smart switch run
pumps and static pump.
When setting value is 0000 minutes, the automatic switching is invalid; when
setting value is 0001,the system will automatically switch one time in each
restarted time. when work it would’t switch: when setting value is above 0002,the
system will automatically switch by setting value.
F3.26 Water supply supervision Para. display Range: 0, 1 0
0: C-11, C-12 display voltage value of VCI, CCI.
1: C-11, C-12 display PID specified pressure and feedback pressure.
F3.27 Closed-loop adjusting characteristic Range: 0, 1 0
0: Forward function. motor speed increases as specified value increases.
1: Reverse function. motor speed decreases as specified value increases.
F3.28 LED initial supervision Para. selection Range: 0~14 1
This parameter defines initial supervision parameter selection during running or
stop. For example F3.28=3, LED displays output voltage initially, please press
SHIFT key if you want to see about other supervision parameter.
0: set frequency: Standby mode display set the frequency, output frequency
is displayed after running.
1: output frequency: Display output frequency not only standby but also
running .
2: output current
3: output voltage
4: DC bus bar voltage
5: motor speed
6: heat sink temperature
7: run time
8: accumulative run time
9: input terminal status
10: output terminal status
11: analog input VCI/PID provision
12: analog input CCI/PID feedback
13: analog input YCI
