COMBIMASTER: These parameters are set in the factory
and should not be changed under normal circumstances.

P086
••••
Motor current limit (%)
0 - 250
[150]
The motor current can be limited with this parameter. If the
set value is exceeded, the output frequency is reduced until
the current falls to this limit. During this process, both LEDs
will flash
(see Operating Information, Section 5)
.
P087
Motor PTC enable
0 - 1
[0]
Change this parameter only when the PTC option is fitted.
0
= Disabled
1
= Motor PTC enabled
If P087 =
1
and the Motor PTC input goes high then the
inverter will trip (fault code F004). Note that if the internal
PTC gets too hot, the inverter will trip (fault code F005).

Serial link slave
address

[0]
Up to 31 COMBIMASTERS can be connected via the serial
link and controlled by a computer or PLC using the USS
protocol. This parameter sets a unique address for the
inverter.
