extBlockChange
4)
IN BOOL FALSE = Edge FALSE → TRUE: The active block is interrupted and
the next block is selected.
= FALSE: No external block change
noStopIntermediate IN BOOL FALSE = TRUE: No intermediate stop or block in intermediate stop
is resumed
= FALSE: Intermediate stop
Interruption of current travel requeststart is not accepted
noStop IN BOOL FALSE = TRUE: No stop
= FALSE: Stop
Abort of current travel request If start parameter is set at the
same time, start is not accepted.
blockNumber IN BYTE 16#00 Traversing block numbers 3 to 27
Single block or program
blockNumber = 3 → MDI operation
resetError IN BOOL FALSE Acknowledges fault
1. Remedy cause of fault.
2. FALSE → TRUE edge
3. Parameter must remain set to TRUE until driveError =
FALSE.
setStartInformation IN BYTE 16#00 Start byte
Bit combination transmitted to the drive as an additional start
requirement.

mdiMode
3)
IN BOOL FALSE = TRUE: MDI relative
The value in the mdiPosition parameter is evaluated relative
to the current position
= FALSE: MDI absolute
The value in the mdiPosition parameter is evaluated in ab‐
solute terms relative to the drive zero position set by homing.

IN INT 0 Velocity of MDI travel (0 to 100%)
mdiAcceleration
3)
IN INT 0 Acceleration of MDI travel (0 to 100%)
mdiPosition
3)
IN REAL 0 Target position of MDI travel
Value range: -2 • 10

reqControl
4)
IN BOOL FALSE Control requested by the open-loop control
p701 = 1: Message frame substitution active
= TRUE: PROFIBUS data are taken over by the POSMO A
= FALSE: Data from the PROFIBUS are frozen; the data last
received are used
p701 = 0: Message frame substitution inactive. Behavior as
for POSMO A before software version V3.0
