12.8 H: Terminal Functions

You cannot set the Reference Sample Hold function at the same time as these functions:

• H1-xx = A [Accel/Decel Ramp Hold]

• H1-xx = 10, 11 [Up Command, Down Command]

• H1-xx = 44 to 46 [Offset Frequency 1 to 3]

• H1-xx = 75, 76 [Up 2 Command, Down 2 Command]

If you set them at the same time, the drive will detect oPE03 [Multi-Function Input Setting Err].

20 to 2F: External Fault

Setting Value

External Fault

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.

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)

shows the relation between the conditions and the value set to H1-xx.
