and continue the PLC operation. Refer to F4.00~F4.14 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 F7.08 .
17~18: External interrupt signal normally-open input
When the drive receives an interrupt signal during running, it
will stop outputs and run at zero frequency. Once the signal
removed, the drive will resume previous running at start
frequency.
As Figure 5-40 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 drive 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 F2.09~F2.11.
Braking time is decided by the bigger value between F2.12
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.
Note
The switching between operation modes is possible when the
drive is in close-loop mode (F5.00=1) .
When the drive is switched to low level operating mode, its
start/stop, operating direction, ACC/Dec time are shifted to
the corresponding operating modes accordingly.
21: Disable PLC
If the setting is 21, the terminal is used to realize the flexible
switching between PLC operation and low level operating
mode.
Note
The switching between operation modes is possible only when the
drive is in PLC operation (the one's place of F4.00 is not 0) .
When the drive is switched to low level operating mode, its
start/stop, operating direction, ACC/Dec time are shifted to
the corresponding operating modes accordingly.
22~24: Reference frequency setting method
EV1000 Series General Purpose Variable Speed Drive User Manual
Through the combination of the ON/OFF state of X1, X2 and
X3, you can select different frequency setting method, which
will come into effect regardless of F0.00.

25: Frequency reference is input via terminal CCI
If the setting is 25, the frequency reference will be input via
terminal CCI forcibly. The frequency input will be changed to
the previous one if this terminal function is disabled.
26: Not used
27: Terminal control mode is enabled
When this terminal function is enabled, the operating
command is input through this terminal forcibly. The drive will
be controlled in the previous mode if FWD/REV terminal
function is disabled.

traverse function is enabled if this function is selected. Refer
to F6.
