d21 Select ACI / Deselect AVI:

Parameter value d21 allows the user to select the input type ACI or AVI via an external switch. AVI is

selected when the contact is open and ACI is selected when the contact is closed. Please note: the

use of this feature will override Pr.2-00 programming and the jumper of the front of the drive must be

moved to the correct location either across the AVI or ACI pin head.

d22 PID function disable:

When input ON with this setting, PID function will be disabled.

d23 JOG FWD:

This function could be operated only when the AC motor drive is stop. The operation direction is forward, can’t be changed and can be stopped by the STOP key on the keypad. When the contact is OFF, the AC motor drive will stop by the JOG decel time. Refer to the Pr.1-13 and Pr. 1-14 for detail.

d24 JOG REV:

This function could be operated only when the AC motor drive is stop. The operation direction is forward, can’t be changed and can be stopped by the STOP key on the keypad. When the contact is OFF, the AC motor drive will stop by the JOG decel time. Refer to the Pr.1-13 and Pr. 1-14 for detail.

d25 The source of master frequency is AVI. (The priority is higher than Pr. 2-00 and d26) d26 The source of master frequency is ACI. (The priority is higher than Pr. 2-00)

d27 Press UP/DOWN key to switch forward/reverse (N.O.) motion:

When this function is enabled, press key for forward motion and key to REV (N.O.)

motion. The keys and will be disabled.

d28 Press UP/DOWN key to switch forward/reverse (N.C.) motion:

When this function is enabled, press key for forward motion and key to REV (N.C.)

motion. The keys and will be disabled.
