Enable 3-wire operation--HLD)
(Function code data = 6)
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)
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)
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)
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
0h2
.
The motor will coast to a stop.
Ready for jogging--JOG
(Function code data = 10)
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
