Example
In the following example three steps are executed. They cause the axis to make a move, wait, and then make
another move:
Step 15 Step 16 Step 17
Mode 00001 00001 00001
Accel 100 100 100
Decel 100 100 100
Speed 10000 10000 10000
Command Value 15500 10000 3000
Command G G
Link Type B D 0
Link Value 00001 500 0
Link Next 16 17 0
Step 15 issues a “Go” command to 15.5 inches (15500). The link type is B with a link value of 00001, which
causes the MMC120 to look for the least significant bit in the status word (the In Position bit). When the In
Position bit turns on, indicating the move is complete, Step 16 (Link Next - 16) is executed.
Step 16 has no command entered, so no command is issued. The link type is a Delay with a value of 500
milliseconds. After 500 milliseconds pass, Step 17 executes.
Step 17 issues a “Go” to 3 inches. The Link Type 0 (zero) causes the axis to terminate the sequence.
Starting a Sequence
Triggering Events
To trigger or start an event sequence, place the Step number you want to execute (0 to 255) in the Command
Value field, then issue an 'E' command.
Mode 00001 Not used (can be any value)
Accel 100 Not used (can be any value)
Decel 100 Not used (can be any value)
Speed 10000 Not used (can be any value)
Command Value 4 Execution will begin at Step 4
Command E 69 Decimal (45 Hex)
Ending a sequence
A Halt, Quit, or Kill command will cause the axis to stop executing Steps. A Quit or Kill command also sets
the Step # to 0, and a Kill command also puts the axis in the emergency stop state. The preferred way to end a
sequence is with a Link Type 0.
