8. Coding of process data
The same process data information is used across all fieldbus systems for the control and
setpoint input. The coding of the process data is carried out according to the uniform MOVIL -
INK profile for SEW drive inverters. For MOVIMOT, it is generally possible to differentiate the
following variants:
• Two process data words (2PD)
• Three process data words (3PD)
PO Process output data
PO1 Control word
PO2 Speed (%)
PO3 Ramp
DO Digital outputs
Communication between podis
podis MOT also allows the additional connection of sensors and actuators at digital input and
output terminals via the two M12 sockets X4 and X5.
In the PROFIBUS-DP protocol, an additional I/O byte is attached after the process data for
MOVIMOT in which the additional digital inputs and outputs are mapped.
The coding is once again carried out according to the uniform MOVILINK profile for SEW
drive inverters.
Communication between master and slave
To control MOVIMOT via two process data words (2PD), the process output data control word
and speed (%) are send from the higher-level automation device to MOVIMOT and the process
input data status word 1 and output current are transferred from MOVIMOT to the automation
device.
For control via three process data words, the ramp is transferred as additional process output
data word and status word 2 as the third process input data word.
