Using the connector-binector converters, the bits can be extracted from two of the PZD receive words 3 to 8 and used as binectors.
The following representation applies for words: 4000 hex = 100 %.
The reference variables p200x apply for the ongoing interconnection (100 % -> p200x).
The following applies for temperature values: 100° C -> 100 % = 4000 hex, 0° C -> 0 %.

The receive word 1 must be used as control word (STW1) (due to bit 10 "control requested").
The preconfiguration is set automatically via p0700 = 6.
The preconfiguration with the speed setpoint is set automatically via p1000 = 6.
