Parameters Description
Substitute value
1)
On failure of the bus connection or CPU stop, the 3RW55 and 3RW55 Failsafe soft
starters can be controlled by a substitute process image output.
• Motor CW
• Motor CCW
• Reset
• Emergency start
• Creep speed
2)
• Output 1
• Output 2
• Parameter set 1
• Parameter set 2
• Parameter set 3
• Disable Quick-stop
• Output 3
2)
• Start pump cleaning (only adjustable via user program)
• Manual operation local - Input controlled (only adjustable via user program)
• Use alternative stopping mode
• Motor standstill
Parameters of CPU / master disabled This parameter de󹪝nes how the 3RW55 and 3RW55 Failsafe soft starters process
the parameter values received from the controller. Setting the parameters only
a󹪜ects the device parameters of the 3RW55 and 3RW55 Failsafe soft starters.
Device parameters of the 3RW5 HMI High Feature and of the 3RW5 communica‐
tion module are always overwritten regardless of how the parameters are set.
• Deactivate (factory setting)
The parameters set on the 3RW55 or 3RW55 Failsafe soft starter are overwrit‐
ten on bus startup by the values stored in the con󹪝guration software of the
controller.
• Activate
The soft starter acknowledges to the controller the correct receipt of all the
parameter values sent to it by the controller via cyclic and acyclic communi‐
cation channels. The 3RW55 or 3RW55 Failsafe soft starter then rejects these
values. This prevents the parameters stored in the 3RW55 and 3RW55 Failsafe
soft starters from being overwritten.
• Activate only for startup parameter
The parameterization block only a󹪜ects the starting parameters upon start-
up. The setting is only possible together with a 3RW5 PROFINET or PROFIBUS
communication module.
