Usage rate brakeres.

(Actual brake resistor usage rate)

0 ... 1000 %

This parameter provides information about the actual degree of modulation of the brake chopper
or the current utilisation of the braking resistor in generator mode.

If parameters P556 and P557 are correctly set, the utilisation related to P557, the resistor power,
is displayed.

If only P556 is correctly set (P557=0), the degree of modulation of the brake chopper is displayed.
Here, 100 means that the brake resistor is fully switched. On the other hand, 0 means that the
brake chopper is not active at present.

If P556 = 0 and P557 = 0, this parameter also provides information about the degree of
modulation of the brake chopper in the FI.

Usage rate motor

(Actual utilisation of motor)

0 ... 1000 %

Shows the actual motor load. Basis for calculation is the motor data P203. The actually recorded
current is related to the nominal motor current.

Heat sink temp.

(Actual temperature of heat sink)

0 ... 150 °C.

Displays the actual temperature of the FI.

[-01] = Heat sink temp. 1: Heat sink temperature of the FI, shows the actual temperature of

the heat sink. This value is used for overtemperature switch-off (E001), error
message 1.0.

[-02] = Heat sink temp. 2: Internal temperature of the FI, shows the actual internal

temperature of the inverter. This value is used for overtemperature switch-off (E001),
error message 1.1.

[-03] = Heat sink temp. 3: Motor temperature KTY temperature sensor, shows the actual

motor temperature when monitoring with a KTY temperature sensor.

Process Data Bus In

(Process data Bus In)

S

0000 ... FFFF (hex)

This parameter informs
about the actual control
word and the setpoints that
are transferred via the bus
systems.

For display, a BUS system
must be selected in P509

[-01 ] = Control word

Control word, source from
P509.

[-02] = setpoint value 1
[-03] = setpoint value 2
[-04] = setpoint value 3
[-05] = setpoint value 4
[-06] = setpoint value 5

Setpoint data from main
setpoint (P510 [-01]).

[-07] = Bus I/O In Bits (P480)

The displayed value depicts all
Bus In Bit sources linked with
"OR".

[-08] = Parameter data In 1
[-09] = Parameter data In 2
[-10] = Parameter data In 3
[-11] = Parameter data In 4
[-12] = Parameter data In 5
