Parameters
Parameters
Description
Response to CPU/Master Stop With this parameter, you define how the 3RW5 soft starter will behave if a
CPU/master stop stop occurs:
• Switch substitute value (factory setting)
The process image output of the 3RW5 soft starter is automatically changed to
the values defined in the following parameter "Substitute value".
• Keep last value
The 3RW5 soft starter does not change the process image output. The current
control commands are retained.
Substitute value
1)
In the event of a bus failure, the 3RW5 soft starter is controlled by a corresponding
substitute process image output (depending on the 3RW5 soft starter).
• Motor CW
• Motor CCW
• Reset
• Emergency start
• Creep speed
• Output 1
• Output 2
• Parameter set bit 0
2)
• Parameter set bit 1
2)
• Disable quick-stop
• Output 3
• 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
• Deactivate (factory setting)
The parameters set on the 3RW5 soft starter are overwritten on bus startup by
the values stored in the configuration 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
communication channels. The 3RW5 soft starter then rejects these values. This
prevents overwriting of the parameters stored in the 3RW5 soft starter.
1)
In the 3RW5 HMI High Feature, the parameter is only visible if "Substitute value" is selected in the parameter
"Response to CPU / Master Stop".
2)
Explanation in the following table. When making the settings via the 3RW5 HMI High Feature, observe the Equipment
Manual of the 3RW5 soft starter.
