DISPLAY MODE PARAMETERS......................................
Parameter Function Range Default Units
Operating display - (output frequency) Hz
Displays the output selected by P001 (an Expert mode parameter).
Display selection via P001:
0 = Output frequency (Hz) 4 = Motor torque (% nominal)
1 = Frequency setpoint (i.e. speed at 5 = Motor speed (rpm)
which inverter is set to run) (Hz) 6 = USS serial bus status (Code)
2 = Motor current (A) 7 = PID Feedback signal (%)
3 = DC-link voltage (V) 8 = Output voltage (V)
The default setting (0) displays the inverter output frequency. If the inverter is in stand-by mode, the
flashing display will alternate between the setpoint frequency and actual output frequency, which will
be 0 Hz when not being run.
In the event of a failure, the relevant fault code (Fnnn) is displayed.
BASIC MODE PARAMETERS………………………………
Parameter Function Range Default Units
Ramp-up time 0 - 150.0 20 Seconds
This is the time taken for the motor to accelerate from standstill to the maximum frequency. The
maximum frequency is set by parameter P013. Setting the ramp-up time too short can cause the
inverter to trip (Fault code F002 = overcurrent).
Ramp-down time 0 - 150.0 20 Seconds
This is the time taken for the motor to decelerate from maximum frequency to standstill. The
maximum frequency is set by parameter P013. Setting the ramp-down time too short can cause the
inverter to trip (Fault code F001 = DC link overvoltage). This is also the period for which injection
braking is applied, if selected (refer to parameter P073 in Expert mode).
Frequency setpoint
source selection
0 – 2 0 -
The value of this parameter (0, 1 or 2) selects the mode of control of the inverter’s frequency
setpoint.
0 = digital motorised potentiometer. The inverter runs at the frequency set in P005 (refer to
Expert mode) and can be controlled with the [up] and [down] keys. If P007 (see below) is
set to 0, the frequency can be increased or decreased by setting any two of the digital
inputs (P051 to P055 or P356 - refer to Expert mode) to the values of 11 and 12.
1 = Analog. The inverter output frequency is controlled by analog input signals (0-10V, 0/4-
20mA or potentiometer).
2 = Fixed frequency. Fixed frequency is only selected by setting the value of at least one of
the digital inputs (P051 to P055 or P536 - refer to Expert mode) to the value of 6 or 7.
