Universal DI -- U-DI (Function code data = 25)

Using U-DI enables the inverter to monitor digital signals sent from the peripheral equipment
via an RS-485 communications link or a fieldbus option by feeding those signals to the digital
input terminals. Signals assigned to the universal DI are simply monitored and do not operate
the inverter.
 For an access to universal DI via the RS-485 or fieldbus communications link, refer to
their respective Instruction Manuals.
Enable auto search for idling motor speed at starting -- STM (Function code data = 26)

This digital terminal command determines, at the start of operation, whether or not to search
for idling motor speed and follow it.
 Refer to H09 (Starting mode).
Force to stop -- STOP (Function code data = 30)

Turning this terminal command OFF causes the motor to decelerate to a stop in accordance
with the H56 data (Deceleration time for forced stop). After the motor stops, the inverter
enters the alarm state with the alarm Er6 displayed.
 Refer to F07.
Reset PID integral and differential components -- PID-RST (Function code data = 33)

Turning this terminal command ON resets the integral and differential components of the PID
processor.
 Refer to J101 through J131 and J201 through J231.
Hold PID integral component -- PID-HLD (Function code data = 34)

Turning this terminal command ON holds the integral components of the PID processor.
 Refer to J101 through J131 and J201 through J231.
Select local (keypad) operation -- LOC (Function code data = 35)

This terminal command switches the sources of run and frequency commands between
remote and local.
 For details of switching between remote and local modes, refer to Chapter 5, Section
5.5.4 "Remote and local modes."
Enable run commands -- RE (Function code data = 38)

Once this terminal command is assigned to any digital input terminal, the inverter no longer
starts running with a run command only. Upon receipt of a run command, the inverter gets
ready to run and outputs an AX2 signal ("Run command entered").
Entering an RE signal ("Enable run commands") when the inverter is ready for running starts
the inverter to run.
