• 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.

Signal Input Method from

Peripheral Devices

Set the terminal to N.O. (detects external fault when switched ON) or N.C. (detects external fault when switched OFF).

Set the drive to always detect each fault or to detect only during run.

30: PID Integrator Reset

Setting Value

PID Integrator Reset

Refer to "PID control block diagram" for more information.
