HAND
/
AUTO
).
Connection example:
Note! Parameter 2107
START INHIBIT
should be 0 (
OFF
).
Hand-Auto default parameter values:
Input signals Output signals DIP switch
• Start/stop (DI1,5) and rev
(DI2,4)
• An. output AO: Frequency
• Two an. references (AI1,AI2) • Relay output 1: Fault
• Control location selection (DI3) • Relay output 2: Running
