Binary inputs and outputs
If neither a DIO nor DIP is inserted in MOVIDRIVE
®
, the bits in control word 2 / status
word 2 can be addressed in the IPOS
plus®
program as follows:
• Directly with the symbolic names DI10 ... DI17 or DO10 ... DO17
• Read indirectly with GETSYS and written with SETSYS
In this case, they can be described as binary inputs and outputs simulated via virtual ter-
minals. The meaning of the terminals can be set via parameters P610 ... P617 or
P630...P637.
8.2.1
Fieldbus interface, DIO and DIP
If a DIO or DIP is inserted in MOVIDRIVE
®
, the organization of the terminal assignment
moves as described for the affected system variables (see below), and the process data
can only be accessed via GETSYS and SETSYS:
8.3
Cyclical process data
Cyclical process data is read and written in a time slice of 5 ms.
8.3.1
Cyclical preset process data
If a value, for example, SPEED is set in the parameters P870 ... P875, the process data
item is linked directly with an internal value.
The drive receives a double word as a position setpoint. MOVIDRIVE
®
copies this value
to variable H499 SetpPosBus and, if P916 ramp type is set to BUSRAMP, it automati-
cally uses this value as the position setpoint. If P916 Ramp type = LINEAR, SINE,
SQUARED or JERK LIMITED, the setpoint can be further processed in the user program
or copied directly to a target position H492 TargetPos or H454 ModTagPos using one
of the following commands.
• TargetPos = SetpPosBus; (Compiler)
• SET H492 = H499 (Assembler)

INFORMATION
The double word with the actual position value that is sent from the drive to the PLC
in the example is always the position from H509 ... H511 of the encoder selected in
P941 Source actual position.
