15
command switch to
keyboard control
It is used to select different running signal sources, and can switch the inverter
running command among keyboard, terminal and communication
16
command switch to
terminal control
17
command to switch to
communication control
18
The main frequency
source is switched to
digital given
When this function terminal is valid, the main set frequency channel is forced
to switch to digital reference, A I1 or A I2
19
The main frequency
source is switched to A I1
20
The main frequency
source is switched to A I2
24
Multi-stage command
terminal 1
Through 16 states of these four terminals, 15 - stage speed setting can be
realized.
25
Multi-stage instruction
terminal 2
26
Multi-stage instruction
terminal 3
27
Multi-stage command
terminal 4
28
Acceleration and
deceleration time
selection terminal 1
Through the 4 states of the secondary terminal, the selection of 4 acceleration
and deceleration times is realized.
29
Acceleration and
deceleration time
selection terminal 2
34
Forward rotation
prohibited
Prohibit forward running
35
Reversal prohibited
Prohibition of reverse operation
36
Acceleration and
deceleration prohibited
Maintain current output frequency (except stop command)
37
UP /DN setting reset
When the main frequency is set through the panel, the terminal selects this
function to clear the frequency value changed by the up and down keys on
the keyboard, and restore the given frequency to the setting of F 0.05
43
P ID points suspended
PID is suspended, and the proportional adjustment and differential adjustment
are still valid at this time .
44
PID forbidden
P ID function is invalid, if the frequency source is given by closed-loop P ID ,
the system will switch to F 9.29 channel setting
45
P ID is reversed
P ID is opposite to the direction set by F 9.15
48
DC braking The inverter directly switches to the DC braking state
49
Frequency setting start
terminal
If the terminal is valid, it is allowed to modify the frequency, if the terminal is
invalid, it is forbidden to modify the frequency.
51
This run time is cleared
Even if the time is reset to zero when the inverter is running this time,
note： Serial numbers not listed in the table are "reserved".
8.11.2 Digital output terminal function (DO)
NVF2G-S series inverters are equipped with 1 multi-function digital output terminal and 2 multi-function
relay output terminals as standard, and each terminal can set the following output terminal functions.
