5.4 Parameterize motor temperature sensor evaluation
You can connect a maximum of two PTC triplets or one KTY. If the nominal trig-
gering temperature has been reached, the PTCs increase their ohmic resistance
by a considerable factor. The KTY 84 has a linear characteristic curve, which al-
lows analogue measurement of the motor temperature. The measurement is re-
stricted to one motor coil, which is why the motor protection is restricted in
comparison with a PTC triplet.
B38 = 0:PTC,
B38 = 1:KTY 84-1xx
In the B38 Motor temperature sensor parameter, set whether you will evaluate
PTC drilling or a KTY 84-1xx.
In B39 Maximum motor temperature, set the maximum permitted temperature of
the motor. If this is reached, the 41:TempMotorTMP malfunction is triggered.
The motor temperature measured by the KTY is displayed in E12 Motor temper-
ature.
Information
Please note that the temperature sensor evaluation in the inverter is al-
ways active. If operation without temperature sensor is permissible, the
connections on X2 will have to be bridged. A fault is triggered if the con-
nection is not bridged when the inverter is switched on.
Information
Note that the evaluation of a KTY84-130 on the FDS 5000 is possible
with a hardware version of 200 or higher. Before using a KTY, note that
motor protection is not ensured to the same extent as when monitoring
with PTC drilling.
