0.01- Can be used instead of P088 to set the
199.99 motor stator resistance manually. The value
¶¶¶
[ ] entered should be the resistance measured
across any two motor phases.
WARNING:
The measurement should be made at the
inverter terminals with power off.
If the value of P089 is too high then an
overcurrent trip (F002) may occur.
0 - 30 Up to 31 inverters can be connected via the
[0] serial link and controlled by a computer or
PLC using the USS serial bus protocol. This
parameter sets a unique address for the
inverter.
3 - 7 Sets the baud rate of the RS485 serial
[6] 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.
0 - 240 This is the maximum permissible period
[0] 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.
0 - 150.0 Setpoints are transmitted to the inverter via
[50.0] the serial link as percentages. The value
(60)North entered in this parameter represents 100%
America
(HSW = 4000H).
0 - 2 0 = Compatible with 0.1 Hz resolution
[0] 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).
