Parameter
set
P737
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.
P738 [-01]
[-02]
Usage rate motor
(Actual utilisation of motor)
0 ... 1000 % Shows the actual motor load. Basis for calculation is the motor data P203. The actual recorded
current is related to the nominal motor current.

Heatsink temperature
(Actual heat sink temperature)
-40 ... 150 °C [-01] = Heat sink temperature
[-02] = Ambient temperature (Internal temperature of the FI)
[-03] = Temp Motor KTY, motor temperature via KTY, recording only via IO extension, setting
in parameter (P400) to function {30} "Motor temperature"

PZD bus in
(Process data bus in)
S
0000 ... FFFF (hex) This parameter provides information about the actual control word (STW) and the setpoints
(SW1-3) that are transferred via the bus systems.
For values to be displayed, a bus system must be selected in P509.
For standardisation of actual values: See also (Section 9.10).
[-01] = Control word (P509) Control word, source from (P509).
