1258 [Enable PI PD]
Indicates the combined status of Par 769 [Enable PI] and 770 [Enable PD]. If both
Par 769 and Par 770 are enabled then Par 1258 [Enable PI PD] displays “Enabled”. If
either of Par 769 or Par 770 is disabled, Par 1258 [Enable PI PD] displays “Disabled”.

Init Diam Calc
794 [Diameter Calc]
Enables/Disables the diameter calculation function. If this parameter has been
programmed via a digital input, it must be brought to a logical high level.
• “0” = The diameter calculation is disabled.
• “1” = The diameter calculation is enabled.

16-bit
Int
796 [Max Deviation]
A value, expressed in counts of D/A, that corresponds to the position of maximum
shift admitted by the dancer. This value is considered the starting measurement of
the dancer movement during the initial diameter calculation phase.
