Description / Notes
P092
••••
Serial link baud rate
3 – 7
[6]
Sets the baud rate of the RS485 serial interface (USS
protocol):
3
= 1200 baud
4
= 2400 baud
5
= 4800 baud
6
= 9600 baud
7
= 19200 baud
Some RS232 to RS485 converters are not capable of baud
rates higher than 4800.
P093
••••
Serial link timeout
(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.
P094
••••
Serial link nominal
system setpoint (Hz)
0 -
fmax**
[50.00]
Setpoints are transmitted to the inverter via the serial link as
percentages. The value entered in this parameter
represents 100% (HSW = 4000H). – refer to USS reference
document (see Section 5.7)
P095
••••
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).
Note : Unit will only output 0.05Hz resolution
P099

0 - 2
[0]
0
= Option module not present
1
= PROFIBUS module (enables parameters relating
to PROFIBUS)
2
= CANBUS
(SW Version : 3.00 onwards)
P101
••••
Operation for Europe
or USA
0 - 1
[0]
This changes the power display between kW and HP:
0
= Europe (kW)
1
= USA (HP)
P111
Inverter power rating
(kW/hp)
0.0-10.00
[
!!!
]
Read-only parameter that indicates the power rating of the
inverter in kW. e.g. 0.55 = 550 W
If P101 = 1 then the rating is displayed in hp.
P112
Inverter type
1 - 8
[8]
Read-only parameter.
1
= MICROMASTER series 2 (MM2)
2
= COMBIMASTER
3
= MIDIMASTER
4
= MICROMASTER Junior (MMJ)
5
= MICROMASTER series 3 (MM3)
6
= MICROMASTER Vector (MMV)
7
= MIDIMASTER Vector (MDV)
8
= COMBIMASTER/MMI series 2
Read only parameter

0
= RUN button disabled.
1
= RUN button enabled (only possible if
P007=1).
