(Function code data = 6)
㩷
Digital input signal
HLD
may self-hold the forward
FWD
/ reverse
REV
run com-
mands given at the external signal input terminals to enable 3-wire inverter opera-
tion.
Shorting the circuit between the
HLD
-assigned terminal and terminal [CM] (i.e.,
when
HLD
is ON) will self-hold the
FWD
or
REV
command. Opening the circuit will
release the hold. When
HLD
is not assigned, 2-wire operation involving only
FWD
and
REV
takes effect.
„ Coast to a stop--
BX
(Function code data = 7) 㩷
Shorting the circuit between the
BX
-assigned terminal and terminal [CM] will im-
mediately stop the inverter output so that the motor will coast to a stop without is-
suing any alarms.
„ Reset alarm--
RST
(Function code data = 8)
㩷
When the protection 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.
„
Enable external alarm trip--
THR
(Function code data = 9) 㩷
When the motor is running, opening the circuit between the
THR
-assigned terminal
and terminal [CM] will immediately stop the inverter output and issue the alarm
J
.
The motor will coast to a stop.

Ready for jogging--
JOG
(Function code data = 10) 㩷
You can choose either one of jogging operations specified following:
(1) When operated from keypad (F02 = 0, 2, or 3)
By state of key on the keypad the motor becomes ready for:
ON Start jogging
OFF Stop jogging
(2) When operated from the digital inputs ([FWD] and [REV]) (F02 = 1)
By state of the digital inputs [FWD] and [REV] the motor becomes ready for:
ON Start jogging
OFF Stop jogging
Jogging operation follows the settings of:
- Jogging frequency set by function code C20
- Acceleration or deceleration time set by function code H54
