group 6 – technical functions.
Operating Hours – Parameter 600
Readout of inverter operating time, updated hourly.
Run Hours – Parameter 601
Readout of inverter running time, updated hourly.
Power Ups – Parameter 603
Readout of number of power-ups.
Over Temperatures – Parameter 604
Readout of temperature faults.
Over Voltages – Parameter 605
Readout of over-voltage faults.
Fault Log – Parameter 615
Readout of last 10 trip codes, the lowest log number contains the
latest fault. (See Page 5 for Fault Code list).
Fault Log Time – Parameter 616
Readout shows total number of operating hours before trip
occurred. The lowest log number contains the latest data.
Fault Log Value – Parameter 617
Readout shows current or voltage when the trip occurred.
Reset Hours Run Counter – Parameter 619
To reset the hours run counter in parameter 601 to zero select 1.
Inverter Data – Parameters 620-635
Read only values of inverter identification numbers.
group 7 – sensorless functions.
Sensorless Control On/O – Parameter 700
Set to ‘on’ for Sensorless control. For all other modes of control
set to ‘o’.
Power Error – Parameter 701
Normally set to 20W, this allows a fast but rough response to
the output hz. Not normally changed.
Delta Frequency – Parameter 702
Normally set to 0.2 hz, as parameter 701, this allows a fast but
rough response to the output hz. Not normally changed.
Integral Power – Parameter 703
Normally set to 20, this allows more precise adjustments to the
output hz. Not normally changed.
Integral Frequency – Parameter 704
Normally set to 20, as parameter 703, this allows more precise
adjustments to the output hz. Not normally changed.
Quadratic Head – Parameter 705
Normally set to ‘on‘. In the ‘o’ position a linear curve between
Min/Max head is produced. In the ‘on’ position a quadratic
curve between Min/Max head is produced.
Head Minimum – Parameter 707
Normally set to 40%. This will provide a 60% reduction in head
at ‘No Flow’ conditions. Set to 100% if a constant head is
required across the full flow range.
Power Consumption – Parameter 708
Normally set to 0 option correction factor that mainly aects
the head reference at high flow values.
Temperature Rise Rated – Parameter 710
Normally set to 80°c. This specifies the estimated dierence
in rotor temperature from idle running conditions to maximum
loaded conditions.
tau Therm. – Parameter 711
Normally set to 300 Seconds. This specifies the estimated time
it will take the rotor temperature to rise from idle temperature to
67% of the maximum temperature, at maximum loaded
conditions.
Slip 0°C – Parameter 712
Normally set to 0%. This specifies the estimated change in
motor slip at the idle temperature compared with the nominal
slip of the motor at idle load.
Slip 100°c – Parameter 713
Normally set to 0%. This specifies the estimated change in
motor slip at the temperature 100°c above the idle temperature,
compared with the nominal slip of the motor at maximum load.
Head Working Point - Parameter 716
Design duty head value (kPa)
Flow Working Point - Parameter 717
Design duty flow value (l/s)
Head Maximum – Parameter 798
Shows the maximum controlled head (at max speed). This
parameter is automatically calculated using parameter 716, 717
and 707.
Protocol – Parameter 561
Fieldbus Communication: fc Protocol, Modbus rtu
