Parameter 08 – Auto Tune Status (ATn Status) *
A 16 bit, binary word represents the auto tune status. A “1” indicates that a
particular state exists. If a “0” is displayed, that state does not exist. Refer
to the list below for an explanation of the individual bits.

Parameter 17 – Velocity Reference Whole (Vel Ref Whole) *
This parameter supplies the whole number part of an internal digital
velocity reference, when internal digital velocity control has been selected
in parameter 132. The data contained in this parameter represents the
whole number of the velocity reference.
Parameter Type: View/modify in Maintenance level
Minimum Value: –8000 rpm
Maximum Value: +8000 rpm
Parameter 18 – Velocity Reference Fraction (Vel Ref Fract) *
The fractional part of an external velocity reference when internal digital
velocity control has been selected in parameter 132 is contained in this
parameter. The data contained represents the low order, fractional part of
the internal digital velocity reference.
Parameter Type: View/modify in Maintenance level
Minimum Value: 0 rpm
Maximum Value: 65535 rpm
Parameter 19 – Final Velocity Command (Vel Command) *
Parameter 19 indicates the value of the velocity reference into the velocity
PI regulator, after the Velocity Mode Select (parameter 132) and the
Velocity Limiter.
Parameter Type: View only, all levels
Minimum Value: –8000 rpm
Maximum Value: +8000 rpm
