with the values stored in the "Creep speed parameters"
menu item (with rotation opposite to the line phase direc‐
tion).

Process data and process images
The basic functions of the 3RW55 and 3RW55 Failsafe soft starters are controlled and monitored
in the process data in the process images.
The process images can be transferred as follows:
• Cyclically in the fieldbus protocol
• Acyclically using data sets
Process image input (PII) and process image output (PIQ)
The following process images are transferred:
• Process image input with 16 bytes
• Process image output with 4 bytes
The tables for the process images describe only the supported process data. Inputs and outputs
that are not listed are not assigned.
