PZD examples
The transmission of the PZD zone is implemented through VFD function code settings.
Example 1: Reading process data from the VFD
In this example, PZD3 is set to "8: Rotating speed during running" through the VFD parameter P15.14.
This operation sets the parameter forcibly. The setting remains until the parameter is set to another
option.
Response (from VFD to master)

Response xx xx xx
Example 2: Writing process data to the VFD
In this example, PZD3 is set to "2: PID reference" through the VFD parameter P15.03. The parameter
specified in each request frame is updated with the information contained in PZD3 until another
parameter is specified.
Request (from master to VFD):

Request xx xx
Subsequently, the information contained in PZD3 is used as tractive force reference in each request
frame until another parameter is specified.
