Emerson EV2000 Series User Manual page 67

Note:
Different with No. 6~7 functions, the external stopping
signal will not trigger alarm and the drive can resume
normal operation after the signal is removed.
19: DC injection braking signal
If the setting is 19, the terminal can be used to perform
DC injection braking to the motor that is running so as to
realize the emergent stop and accurate location of the
motor. Initial braking frequency, braking delay time and
braking current are defined by F2.09~F2.11. Braking
time is the greater value between F2.12 and the
effective continuous time defined by this control
terminal.
20: disabling close-loop function
If the setting is 20, the terminal can be used to realize
the flexible switching between close-loop operation and
low level operating mode (refer to section 4.1.4 for
details).
Note:
The switching between operation modes is enabled only in
close-loop operation (F5.00=1).
When the drive is switched to low level operating mode,
its start/stop, operating direction, ACC/Dec time should
be compliant with corresponding operating modes.
21: disabling PLC
If the setting is 21, the terminal is used to realize the
flexible switching between PLC operation and low level
operating mode (refer to section 4.1.4 for details).
Note:
The switching between operation modes can be enabled
only in PLC operation (unit'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 should
be compliant with corresponding operating modes
accordingly.
22~24: Terminals 1~3 for reference frequency selector.
Different ON/OFF combinations of terminals 1, 2 and 3
can select different reference frequency selectors as
shown in Table 5-8. The drive will act to the command
from the terminal or F0.00, whichever comes late.

25:Frequency reference is input via terminal CCI forcibly
If the setting is 25, the frequency reference will be input
via terminal CCI forcibly. The frequency selector will be
changed to the previous one if this terminal function is
disabled.
26:Reserved
27: Terminal control mode is forcibly enabled
When this terminal function is enabled, the operating
command is input through this terminal forcibly, and the
drive will be controlled in previous control mode if
FWD/REV terminal function is disabled.
