16 Protocol
Selects the application protocol and communication profile for the
network communication.
17 Modbus timeout
The Modbus protocol has no implementation for time-out on
application layer and this may be required when controlling a
drive. A supervision method has been implemented for this
purpose. If Modbus timeout is set to zero, this feature is disabled.
The unit of the parameter is 100 milliseconds (e.g. ‘22’ will give a
timeout of 2.2 seconds).
If the communication fault function of the drive is activated,
Modbus timeout is the sum of communication fault time and the
time defined here.
18 Stop function
Defines the motor stopping method.
Note: This parameter is only effective if the EtherNet/IP network
protocol is selected at parameter 16 Protocol.
19 Output 1
20 Output 2
21 Output 3
22 Output 4
When Modbus/TCP protocol is in use, these parameters define
the output data words or drive parameters that are updated
cyclically between the drive and RETA-01. For the user this can be
seen as faster response for the Modbus queries.
0 = Modbus/TCP
1 = EtherNet/IP AC/DC communication profile
2 = EtherNet/IP ABB Drives communication profile
0=Ramp stop
1 = Coast stop
