I/O Data Mapping Tab
The I/O Data Mapping tab is used to configure the data that will be sent and received from the Profibus Master (PLC) to the Profibus
slave (SM-Profibus-DP module). The Master Receive tab configures the data from the EZMotion module/SP drive to the PLC.
Master Send Tab/Master Receive Tab
Individual parameters are mapped by dragging and dropping the parameter from the Variables list to the desired word. EZMotion
parameters from the variables list can only be mapped to EZMotion parameter words, and SP parameters to SP parameter words.
EZMotion Parameter Words
There are a maximum of 32 EZMotion parameter words available, 24 is the default.
SP Parameter Words
There are a maximum of 8 SP parameter words available, the default is 8.
Total Parameter Words
The total number of parameter words available is 32, These may be divided between EZMotion parameter words and SP parameter
words. This text box shows the number of words allocated vs. the total number available.

Figure 72:
Max Loss Timeout
This provides a method on the drive to ensure that communication with the Profibus master is still present. The SM-Profibus module
resets an internal timer when a valid message is received from the profibus network, if a message is not received within the specified
period of time, in ms, the network loss trip is triggered. Default value is 200 ms, but the range is 0 to 3000 ms.
The network loss trip can be disabled by setting this parameter to 0. In this case, the drive will continue to operate using
the last received values. It is the user's responsibility to ensure that adequate safety precautions are taken to prevent
damage or injury by disabling the drive in the event of a loss of communications.
WARNING
