Sequence State Status
Once the sequence has been initiated the state of the sequence will be
reflected in the Profile Status parameter #236.

The lower 5 bits will tell us which state the control is
commanding. You will observe bit 0 set for 10 seconds in Step 1.
It will then clear and bit #1(second bit) will be set for 10 seconds,
indicating Step #2.

If there were more steps, the first five bits (bits 0-4) of parameter 236
would reflect the present commanded step as a binary value.

Bits #5 and #6 of the status word, reflect the present state of the
profile Enable bit #0 and the Run Sequence bit #1 of the command
word (Profile Enable P235).

The Run Sequence bit is latched while the Enable bit is Not.

This means that once a sequence has begun, and the Run
Sequence bit 1 (of P235) has been set, clearing of the Sequence
bit will be ignored because it is latched.

Beginning a Sequence
At this point, the system should be ready to run the Speed Profile
program. To begin Profile Execution;

1. Set the Enable bit #0 (1st bit) of parameter #235.
2. Press the Green Button (On HIM or GPT terminal) to start the

drive.

3. Set the Run Cycle bit #1 of the Profile Enable parameter #235

to execute profile control.
