I
coil
Current of the adjustable ASC
I
fix
Value of the fixed parallel coil
I
reson
Current at resonance point
If a fixed parallel coil is introduced in the network (“ON” or “Automatic”), the x
axis title of the resonance curve displayed on the HMI can be selected with the
Resonance curve Cur
setting. Available options are:
• Icoil: Only the current of adjustable ASC
• Icoil + Ifix: Total current of adjustable ASC and fixed parallel coil
Statistics
The controller supports displaying resettable statistics. The statistics can be reset
via settings menu using
Clear counters
command.
Table 1590: Displayed statistics
Type Statistics Description
General Operation time Controller time in operation
Tuning procedures Number of started tuning procedures
Tuned Number of successful tuning operations
Canceled tunings Number of the canceled tuning procedures,
that is,
Tuning delay
has not elapsed
Tuned at Uo max Number of tuning cases when coil movement
has stopped to
V Res maximum
position
Tuned at low limit Number of cases when coil final position is
limited either by low end position indication
of the coil or the limited operating range
Minimum current
Tuned at high limit Number of cases when coil final position is
limited either by high end position indication
of the coil or the limited operating range
Maximum current
Earth faults Transient earth-faults Number of transient earth faults (that is,
fault time shorter than time defined in
Tran-
sient time EF
setting)
Permanent earth-
faults
Number of permanent earth faults (that is,
fault time longer than time defined in
Transi-
ent time EF
setting)
Resistor control Switch parallel resis-
tor (auto)
Number of parallel resistor switch opera-
tions. For example, if the resistor is initially
off, then it is switched on and after a defined
delay, it is again switched off, this increases
the counter by two.
Switch parallel resis-
tor (manual)
Number of manual switch operations for par-
allel resistor
Other Motor running time
Sum time of RAISE_OWN and LOWER_OWN
outputs activated
