Enable 3-Wire Operation - Hld; Coast To A Stop - Bx; Reset Alarm - Rst; Enable External Alarm Trip - Thr - FujiFilm FVR-Micro Instruction Manual


Enable 3-wire operation -- HLD (Function code data = 6)
Turning this terminal command ON self-holds the forward FWD or reverse REV run command
issued with it, to enable 3-wire inverter operation.
Short-circuiting the terminals between HLD and [CM] (i.e., when HLD is ON) self-holds the
first FWD or REV command at its leading edge. Turning HLD OFF releases the self-holding.
When HLD is not assigned, 2-wire operation involving only FWD and REV takes effect.
 Coast to a stop -- BX (Function code data = 7)
Turning this terminal command ON immediately shuts down the inverter output so that the
motor coasts to a stop without issuing any alarms.
 Reset alarm -- RST (Function code data = 8)
Turning this terminal command ON clears the ALM state--alarm output (for any fault). Turning it
OFF erases the alarm display and clears the alarm hold state.
When you turn the RST command ON, keep it ON for 10 ms or more. This command should be
kept OFF for the normal inverter operation.
 Enable external alarm trip -- THR (Function code data = 9)
Turning this terminal command OFF immediately shuts down the inverter output (so that the
motor coasts to a stop), displays the alarm
The THR command is self-held, and is reset when an alarm reset takes place.
Use this alarm trip command from external equipment when you have to immediately
shut down the inverter output in the event of an abnormal situation in a peripheral
equipment.
