PZD examples:
Transmission of PZD area is achieved through inverter function code.
Example 1: Reading process data of 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 the VFD to the master station):

Example 2: Writing process data into the VFD
In this example, PZD3 is set to "2: same as 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 the master station to the VFD):
PKW1

Then the content of PZD3 is traction reference within each request frame until a parameter is reselected.
