Description / Notes
•
Serial line time-out
(seconds)
0 - 240
[0]
This is the maximum permissible period
between two incoming data telegrams. This
feature is used to turn off the inverter in the
event of a communications failure.
Timing starts after a valid data telegram has
been received and if a further data telegram
is not received within the specified time
period, the inverter will trip and display fault
code F008.
Setting the value to zero switches off the
control.
•
Serial link nominal system
setpoint (Hz)
0 - 150.0
[50.0]
(60)North
America
Setpoints are transmitted to the inverter via
the serial link as percentages. The value
entered in this parameter represents 100%
(HSW = 4000H).
•
USS compatibility 0 - 2
[0]
0 = Compatible with 0.1 Hz resolution
1 = Enable 0.01 Hz resolution
2 = HSW is not scaled but represents the
actual frequency value to a resolution of
0.01 Hz (e.g. 5000 = 50 Hz).
•
Operation for Europe or
North America
Factory Default
0 for 230V Eco
2 for 380V to 500V Eco
2 for 525V to 575V Eco
0 - 2
[0 or 2]
This sets the inverter for European or North
America supply and nominal rating plate
frequency for the motor to:
0 = Europe (50 Hz and power ratings to kW)
1 = North America NEMA (60 Hz and
power ratings to hp)
2 = Automatic Selection based on mains
voltage
mains voltage <450V goes to 0
mains voltage >450V goes to 1
After setting P101 = 0 or 1 the inverter must
be re-set to factory defaults, i.e. P944 = 1 to
automatically set P013 = 60Hz, P081 =
60Hz, P082 = 1680rpm and P085 will be
displayed in hp.
After setting P101 = 2 the inverter will
automatically re-set to factory defaults, i.e.
P944 = 1
Inverter power rating
(kW/hp)
1.1 - 90.0
[
]
Read-only parameter that indicates the
variable torque power rating of the inverter
in kW. E.g. 7.5=7.5kW
If P101 = 1 then the rating is displayed in hp.
