SUNFAR C300 55
C300 series of non-sensor current vector-control inverter manual
They are used for selecting external terminals Acc/Dec time 1~4.
10
：
Freq. setting channel selection 1
11
：
Freq. setting channel selection 2
12
：
Freq. setting channel selection 3
When F0.1 is 7, Frequency input channel is set by terminals state of 10, 11 and 12.
Refer to the explanation about parameter F0.1.
13
：
Freq. gradually increase to control (UP)
14
：
Freq. gradually decrease to control (DW)
15
：
UP-DW freq. clear
When F0.3 is##0#, one of terminal X1~X6 defined by this parameter have function
of forcible clear.
16
：
Uncontrolled stop control
If one of terminal X1~X6 defined by this parameter is connected with CM, the
inverter will lock output signal and applied motor will stop uncontrolled. Then
inverter will detect speed and restart after terminal is disconnected with CM.
17
：
Fault signal of peripheral equipment input
When one of terminal X1~X6 defined by this parameter, it is connected with CM,
and peripheral equipment is fault. The inverter will lock output signal and display
FU.16.
18
：
Three-line mode running control
When F0.5 is 2, one of external terminal X1~X6 defined by this parameter, it would
stop trigger switch of inverter. Refer to explanation about F0.5.
19
：
DC braking control
When inverter is stop and one of external terminals X1~X6 defined by this
parameter is connected with CM and output freq. is lower than Initial freq. of DC
braking, function of DC braking is valid until terminal is disconnected with CM.
Refer to explanation about F4.4~F4.7.
20
：
Inner counter clear
21
：
Inner counter timer
Only terminal X6 is used for Inner timer, namely parameter F3.3 is 21.
22
：
PLC running valid
When F5.0 is ###2 and any of those parameters is set 22, PLC running is valid.
23
：
PID running valid
When F8.0 is ###2 and any of those parameters is set 23, PID running is valid.
。
24
：
Reserved
25
：
PLC state reset after stopping
If F5.0 is set as #1##, the PLC state will keep fix. But external terminals will force
reset, which is set by this function.
It defines expression content of relay contact and terminals OC1 and OC 2 when
F3.4 Output terminal OC Setting range
：
0 ~ 18
F3.5 A, TB and TC of relay contacts Setting range
：
0 ~ 18
