AMI Reference Manual 11
Here is an example of how the Auxiliary Output functions work in con-
junction with a rotary indexer:
1) Use Aux 3, Output #3 as the Cycle Start relay.
2) When the AMI Output #3 relay is pulsed, pins 7 and 8 of J18 are
momentarily shorted for the amount of pulse time entered. This activity
initiates the “Cycle Start” relay in the rotary indexer control, to start a
cycle or step index.
Note: The pulse time must not exceed the indexer positioning time
to start the next cycle.
3) Once in position, the rotary indexer sends a “Cycle Finish” signal back
to the AMI. The AMI input interprets this as a “GO” signal and per-
forms the next milling operation (Refer to Remote Go on page 7).
This In-Position activity takes place without any outside intervention from
the operator.
G-code Programs
When using a G-code program that requires coolant commands, certain out-
puts are configured to specific commands (M7, M8, M9). The following rules
apply while running G-code programs:
1) M7 command turns on the Aux 1 as the coolant flood relay.
2) M8 command turns on Aux 2 as the coolant mist relay.
3) M9 turns off both Aux 1 and 2.
4) Only one output, Aux 1 or Aux 2, is permitted to be on at a time.
5) These outputs will be turned On and Off as defined in the G-code
program.
6) Auxiliary outputs 3 and 4 are not used and are always off.
