start at start frequency and continue the PLC operation. Refer to
PD.00~PD.08 for the use of this terminal.
15: Acc/Dec prohibit
The motor is immune to any external command except Stop command
and maintain the present speed.
Note
:
This function is disabled during normal decelerating to stop.
16: 3-wire operation control
Refer to P5.08.
17~18: External interrupt signal normally-open input
When the inverter receives an interrupt signal during running, it will stop
outputs and run at zero frequency. Once the signal removed, the inverter
will resume previous running at start frequency.
As Figure 7-7 shows, there are X4, normally open contacts and X5,
normally closed contact.
Note
:
Different from function 6~7, the external interrupt signal will not cause alarm, and
the inverter will resume previous running once the signal removed.
19: DC Braking ( DB )
If the setting is 19, the terminal can be used to perform DC injection
braking to the motor that is running for emergency stop and accurate
location. Initial braking frequency, braking delay time and braking current
are defined by P2.09~P2.11. Braking time is decided by the bigger value
between P2.12 and the period that the terminal is effective.
20: Disable close-loop
If the setting is 20, the terminal can be used to realize the flexible
switching between close-loop operation and low level operating mode.
When the inverter is switched to low level operating mode, its start/stop,
operating direction, ACC/Dec time are shifted to the corresponding
operating modes accordingly.
