62 Position Indexer/Speed Profiler
Profile Command Control Word
The profile/indexer is controlled with [Profile Command], parameter 705. The bit
definitions are as follows:
Bit Name Description
0 Start Step 0 The binary value of these bits determines which step will be the starting step
for the profile when a start command is issued. If the value of these bits are not
1 Start Step 1
1-16 the drive will not run since it does not have a valid step to start from. Valid
2 Start Step 2
Examples: 00011 = step 3, 01100 = step 12
3 Start Step 3
4 Start Step 4
5-7 Reserved Not used
8 Hold Step When set, this command will inhibit the profile from transitioning to the next
step when the condition(s) required are satisfied. When the Hold command is
released, the profile will transition to the next step.
9 Pos Redefine This bit is used to set the present position as Home. When this bit is set,
[Profile Status] bit "At Home" will be set and the [Units Traveled] will be set to
zero.
10 Find Home This bit is used to command the Find Home routine.
11 Vel Override When this bit is set the velocity of the present step will be multiplied by the
value in [Vel Override].
12-31 Reserved Not used.
The bits in [Profile Command] can be set via DPI interface (HIM or Comm) or
digital inputs. When digital input(s) are programmed for "Pos Sel 1-5," the starting
step of the profile is exclusively controlled by the digital inputs. The DPI interface
value for bits 0-4 will be ignored.
If a digital input is configured for bit 8-11 functions of the [Profile Command], the
DPI interface or the digital input can activate the command.
