P000 Operating display - This displays the output selected in P001.
In the event of a fault, the relevant fault code (Fxxx) is displayed (see
section 6). In the event of a warning the display flashes. If output
frequency has been selected (P001 = 0) and the inverter is OFF, the
display alternates between the selected frequency and the actual
frequency.
P001
•
Display mode 0 - 8
[0]
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 = Not used
5 = Motor RPM
6 = USS status (see section 8.2)
7 = Closed loop control setpoint (% of full scale)
8 = Output voltage
P002
•
Ramp up time (seconds) 0 - 650.00
[10.00]
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).

P003
•
Ramp down time (seconds) 0 - 650.00
[10.00]
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 - overvoltage).
This is also the period for which DC injection braking is applied (see P073)
