Description

4-03:

Auto/Manual Select - Contimued

A/M LOC If parameter 28 is set to A/M LOC, then the drive can be set to get its

speed from either an automatic speed source or from the keypad.
When in either Local or Serial Control Mode, this setting allows the
user to change from Auto to Manual or vice versa via the keypad
(when in Local) or the serial link (when in Serial).

A/M SPD If parameter 28 is set to A/M SPD, the drive is forced into AUTO

mode during a transition from LOCAL to REMOTE or from SERIAL
to REMOTE. It forces the drive into MANUAL during the transition
from REMOTE to LOCAL control mode. A/M SPD leaves the Auto/
Man key active at all times enabling the user to toggle their Auto/
Man selection while in REMOTE control mode.

4-04:

Clear Present Fault

If the drive is currently in fault, the fault can be cleared by pressing the STOP key on the
keypad. Overriding 4-04 to (1) simulates the pressing of the STOP key via the serial link.
4-04 will reset to (0) whenever the drive enters a fault condition or serial control is shut
down.
