Procedure
1. Configure the 3RW5 soft starter in the Modbus TCP system.
The following procedures are possible, for example:
– Configuring 3RW5 soft starters without assistance from a 3RW5 HMI High Feature
(Page 73)
– Configuring 3RW5 soft starters with the aid of a 3RW5 HMI High Feature (Page 75)
Refer to the information on Modbus TCP in chapter Configuring the 3RW5 Soft Starter
(Page 73).
2. Parameterize the 3RW5 soft starter. In particular, note the information in chapter
Operation on failure of the bus connection to the controller (Page 88). You will find more
information on parameterization in the Equipment Manual of the 3RW5 soft starter.
Depending on the selection and equipment of the 3RW5 soft starter, you can
parameterize the 3RW5 soft starter in different ways via the
3RW5 communication module:
– Modbus client on PC with Modbus TCP connection
– Configuration software of the controller on PC or programming device with a
Modbus TCP connection.
Note
With Modbus
TCP, you can set only values for parameter set 1 (PS 1) and parameters
(e
.g. input action) that are independent of the parameter set. For PS 2 and PS 3, the
default values are used.
Note
During parameterization of the 3RW5
soft starter, it is possible to select impossible
combinations of interdependent values. In the
"Soft starter diagnostics" data table
(Page
152) the diagnosis "Invalid parameter value" is then signaled. You will find the
dependencies of the parame
ters in the Equipment Manual of the 3RW5 soft starter.
Result
The 3RW5 soft starter is integrated into the Modbus TCP system as a server and
parameterized. You can program the controller and commission the 3RW5 soft starter in the
Modbus TCP system.
