TECO –Westinghouse Motor Company Function Explanation 58
When BX and P24 are connected, inverter output is cut off
immediately and the motor starts to coast-to-stop. An
alarm signal is neither output nor self-held. If BX and
P24 are disconnected when the operation command
(FWD or REV) is on, operation starts at the start
frequency. To use this BX terminal function, assign value
"7" to the target digital input terminal.
When an inverter trip occurs, connecting RST and P24
clears the alarm output (for any fault) ; disconnecting
them clears trip indication and restarts operation. To
use this RST terminal function, assign value "8" to the
target digital input terminal.
Disconnecting THR and P24 during operation cuts off
inverter output (i.e., motor starts to coast-to-stop) and
outputs alarm OH2, which is self-held internally and
cleared by RST input. This function is used to protect an
external brake resistor and other components from
overheating. To use this THR terminal function, assign
value "9" to the target digital input terminal. ON input is
assumed when this terminal function is not set.
This function is used for jogging (inching) operation to
position a work piece. When JOG and P24 are
connected, the operation is performed with the jogging
frequency set in function code C20 while the operation
command (FWD-P24 or REV-P24) is on. To use this
JOG terminal function, assign value "10" to the target
digital input terminal.
Note: It is possible to change to the JOG operation by
keypad panel when keypad panel operation.
WARNING
- When the JOG command and operation command
(FWD/REV) are input at the same time, the inverter can
NOT be changed to the JOG operation and will operate at
set frequency.
- When the JOG operation is used, the operation
command should be input after the JOG command input
while the inverter is STOPPED.
- When the JOG command and operation command are
input at the same time, the JOG command is assigned to
the "Multistep frequency selection (SS1 to SS8)".
- The inverter can NOT be stopped and JOG operation
will continue even if JOG command is OFF during JOG
operation. The inverter will decelerate to a stop if the
operation command is switched OFF.
Accidents may result.
This function switches the frequency setting method set in
function codes F01 and C30 by an external digital input
signal.

Note: It can not be used with set value "35"
simultaneously. When the set value "11" and "35" are
selected, "Er6" is displayed.
This function switches motor constants using an external
digital input signal.
This input is effective only when the operation command
to the inverter is off, operation has stopped, and does not
apply to the operation at 0Hz.

When the external digital input signal is on, DC injection
braking starts when the inverter's output frequency drops
below the frequency preset in function code F20 after the
operation command goes off. (The operation command
goes off when the key is pressed at keypad panel
operation and when both terminals FWD and REV go on
or off at terminal block operation.) The DC injection
braking continues while the digital input signal is on. In
this case, the longer time of the following is selected:
- The time set in function code F22.
- The time which the input signal is set on.
