Select 3-wire operation command--(HLD)
(Function code data = 6)
Digital input signal (HLD) may self-
hold the forward (FWD)/reverse (REV)
run commands given at the external
signal input terminals to enable 3-wire
inverter operation.
Shorting the circuit between the (HLD)-
assigned terminal and terminal [CM]
will self-hold the (FWD) or (REV)
command. Opening the circuit will
release the hold.
If (HLD) is not assigned to any terminal,
the inverter runs in 2-wire operation
using (FWD) and (REV).
Coast-to-stop command--(BX)
(Function code data = 7)
Shorting the circuit between the (BX)-
assigned terminal and terminal [CM]
will immediately shut down the inverter
output so that the motor will coast to a
stop without issuing any alarms.
Reset alarm--(RST)
(Function code data = 8)
When the protective function has been activated (the inverter is in Alarm mode), shorting
the circuit between the (RST)-assigned terminal and terminal [CM] will reset the alarm
output on terminals [Y1] and [30A,B,C]. Opening the circuit will release all the alarm
indications to restart operation. Allow 10 ms or more for the short-circuit time.
(RST) should be kept OFF for normal inverter operation.
Alarm from external equipment--(THR)
(Function code data = 9)
When the motor is running, opening the circuit between the (THR)-assigned terminal and
terminal [CH] will immediately shut down the inverter output and issue the alarm "
0H2 ."
The motor will coast to a stop.
This signal will be self-held inside the inverter until the key is pressed to reset it or any
other reset action is taken. If (THR) is not assigned to any terminal, the inverter interprets
this as (THR) always being ON.
Use this function to protect the external-braking resistor from overheating.
