12.6 H: Terminal Function Selection
308 YASKAWA SIEPYEULA5001C LA500 Technical Manual
If an external fault is input to the drive, the keypad will show EFx [External Fault (Terminal Sx)], where x is the
number of the terminal (terminal Sx) to which the external fault signal is assigned. For example, when an external
fault signal is input to terminal S3, the keypad will show EF3 [External Fault (Terminal S3)].
Use these conditions to select the value to set in H1-xx:
• Signal input method from peripheral devices
• External fault detection method
• Motor stopping method (operation after external fault detection)
Table 12.6 shows the relation between the conditions and the value set to H1-xx.

*1 Set the terminal to N.O. (detects external fault when switched ON) or N.C. (detects external fault when switched OFF).
*2 Set the drive to always detect each fault or to detect only during run.
■ 40: Forward RUN (2-Wire)
Setting Value Function Description
40 Forward RUN (2-Wire)
Sets the Forward Run command for 2-wire sequence 1. Set this function and H1-xx = 41 [Reverse RUN (2-Wire)] together.
ON : Forward Run
OFF : Stop
Note:
• If you turn ON the Forward Run command terminal and the Reverse Run command terminal, it will cause an EF [FWD/REV Run
Command Input Error] alarm and the motor will ramp to stop.
• Initialize the drive with a 2-wire sequence to set the Forward Run command to terminal S1.
• This function will not operate at the same time as H1-xx = 42, 43 [Run Command (2-Wire Sequence 2), FWD/REV (2-Wire Sequence
2)].
