Parameter value (PWE)
According to the type of the PPO or parameter, transfer of the parameter value (PWE) is always as a
word (16 Bit) or double word (32 Bit) Only one parameter value can be transferred in a telegram.
A 32 bit parameter value comprises PWE1 (High value word) and PWE2 (Low value word, 4th word).
A 16 Bit parameter value is transferred in PWE2. For negative values the High word must be set to
FFFF hex.
Information 32 bit parameter values
32 Bit parameter values are only used with the posicon option. All relevant parameters are described in the
supplementary posicon instruction manual.
The parameter value is transferred as an integer value. For parameters with resolutions 0.1 or 0.01
the parameter value must be multiplied by the inverse of the resolution.
Example
A run-up time of 99.99 seconds is to be set.
99.99s à 99.99 * 1 / 0.01 = 99.99 * 100 = 9999
Therefore the value 9999
