terms of set emergency stop mode (
F0.4.54
) and starts to operate with rising edge of running command.
15~16: Frequency or Process PID set value ascending (UP)/descending (DW)
V260 frequency inverter can achieve the setup of operation frequency via external terminal and
long-distance frequency set operation. If the terminal is effective, set frequency increases progressively or
decreases progressively in the light of set speed; if the terminal is ineffective, set frequency keeps same. If
both terminals are effective, set frequencies keep same. See 4~8 parameter functional specifications of
F0.2.25
or
F0.2.26
.
17: UP/DW set frequency zero clearing
Set frequency of external terminal can be cleared to zero through the functional terminal (set frequencies of
frequency increasing progressively command
UP
/decreasing progressively command
DW
). The function
invalidates frequencies set by other frequencies setting modes.
18: External equipment fault
Inputting external equipment fault signal through the terminal is easy for frequency inverter to fault
supervision and communication to external equipment. Since frequency converter receives external
equipment fault, displaying "
Fu.017
" is the external equipment fault and making a stop forcefully.
19: Three wire running control
When select the three-line running mode under the external terminal control (regard
F0.3.33/F0.3.34 as 1),
define three wire running control for input terminal. See Three wire Mode Introduction (regard
F0.3.35 as 2
or
3).
20: Stop DC braking command
When frequency inverter is in the process of deceleration stop and running frequency is lower to straight flow
brake or brake starting frequency or speed, the function is effective. When the terminal status is effective,
execute DC brake; Only when the terminal status is ineffective, DC brake can be stopped. When operate this
function, DC braking functional time F0.4.46 is ineffective.
21: Acceleration and deceleration forbidden
When the terminal is effective, suspend acceleration and deceleration forbidden and frequency inverter
keeps current frequency operation as the acceleration and deceleration achieves; if the terminal is ineffective,
execute ordinary acceleration and deceleration command.
22: Process PID effective
When selecting the multifunctional input terminals in the process PID, the function can achieve process PID's
input and cutting off.
23: Simple PLC multi-stage running effective
When select the multi-stage frequencies or rotation running condition input in the programmable multi-stage
speed operation mode (regard F6.1.15 as ###2), the functional terminal can achieve simple PLC multi-stage
running's input and cutting off.
