Operating display
-
This displays the output selected in P001.
In the event of a failure, the relevant fault code (Fnnn) is displayed
(see
section 7)
or the display flashes in the event of a warning (
see P931)
or If
output frequency has been selected (P001 = 0) and the inverter is in stand-by
mode, the display alternates between the setpoint frequency and the actual
output frequency which is zero Hz.

Display selection:
0
= Output frequency (Hz)
1
= Frequency setpoint (i.e. speed at which inverter is set to run)
(Hz)
2
= Motor current (A)
3
= DC-link voltage (V)
4
= Motor torque (% nominal)
5
= Motor speed (rpm)
6
= USS serial bus status
(see section 9.2)
7
= PID Feedback signal (%)
8
= Output voltage (V)
9 =
Instantaneous rotor / shaft frequency (Hz).
Note:
Applicable only for
Sensorless Vector control mode.
Notes:
1. The display can be scaled via P010.
2.
When the inverter is operating in Sensorless Vector Control
mode (P077 = 3) the display shows actual
rotor / shaft
speed in
Hz. When the inverter is operating in V/f or FCC modes (P077 = 0,
1 or 2) the display shows
inverter
output frequency in Hz.
WARNING:
In Sensorless Vector Control mode (P077 = 3) the display
shows 50Hz when a 4-pole motor is rotating at 1500rpm
which may be slightly higher than the nominal speed shown
on the motor rating plate.

This is the time taken for the motor to accelerate from standstill to the maximum
frequency as set in P013. Setting the Ramp-up time too short can cause the
inverter to trip (fault code F002 - overcurrent).

This is the time taken for the motor to decelerate from maximum frequency (P013)
to standstill, 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 DC injection braking is applied when P073 is
selected.
