POSITION INTERPOLATION
12 BIT
The position specifications sent cyclically by the external controller are
interpolated. Position resolution: 1 revolution corresponds to 4096 incre-
ments (12 bit).
•
Position specification using process data:
–
Set P888
Synchronization time SBus
to 5 ms or 10 ms
–
Set
P100 Setpoint source
to "SBus" or "Fieldbus"
–
Set one process output data word to "position HIGH" and
another one to "position LOW".
•
Position specification via SBus/SCOM object:
–
Set
P888 Synchronization time SBus
to 1 ... 10 ms.
–
Set
P100 Setpoint source
to "BIPOL. FIXED SETPT".
–
Do not set a process output data word to "position HIGH" or
"position LOW".
–
Create a SCOM receive object (using the SCOM receive
command
→
IPOS
plus®
manual) with the target variable
SetpPosBus
(H499).
POSITION INTERPOLATION
16 BIT
The position specifications sent cyclically by the external controller are
interpolated. Position resolution: 1 revolution corresponds to 65536
increments (16 bit).
•
Position specification using process data:
–
Set P888
Synchronization time SBus
to 5 ms or 10 ms
–
Set
P100 Setpoint source
to "SBus" or "Fieldbus"
–
Set one process output data word to "position HIGH" and
another one to "position LOW".
Important:
Position resolution via PI data assignment is 4096
increments per revolution (= 12 bit).
IPOS
plus®
variable H508 provides the motor position, extended
to 16 bits.
The IPOS
plus®
variable
ActPos_Mot
(H511) has a position reso-
lution of 4096 increments per revolution (= 12 bit)

SetPosBus
(H499).
Important:
Position resolution via PI data assignment is 4096
increments per revolution (= 12 bit).
The position resolution of 4096 increments per revolution (= 12
bit) expanded to 16 bit is available on IPOS
plus®
variable H508.
The IPOS

variable
ActPos_Mot
(H511) has a position reso-
lution of 4096 increments per revolution (= 12 bit)

INFORMATION
Note the following for the POSITION "INTERPOLATION 16 BIT" ramp type:
• IPOS variable H508 is also used when S14 is set to ON.
IPOS variable H508 only provides meaningful values when
– DIP switch S14 = "ON"
or
– P916 Ramp type = "Position interpolation 16 bit"
