3.5 Parameter Descrip-
tion
Function (An.41, An.47)
Period (An.46, An.52)
Offset X (An.44, An.50)
Gain (An.43, An.49)
Attention! Only possible with KTY- or PT100 sensors in the motor and appro-
priate factory-installed evaluation!
This option is available starting from housing size G. A KTY- or PT100 sensor ac-
quires the temperature exclusive at one point. Should a complete protection of the
windings be claimed, then it may be realised in consulation with the producer of the
motor, for example with 3 PTC´s and an external analysis unit.
The respective functions are adjusted with these parameters (temperature control
of the power controller or the motor).
The period determines the cycle time in which the output is switched. The period
can be adjusted in a range from 1,0...240,0 s.
The heat sink temperature which shall be controlled is entered with Offset. The
temperature is in a range from 30 °C...50°C for inverters (heat sink temperature /
see power unit data) and in a range from 40°C ...80°C for motors. The adjustment
occurs in percentual values (1% = 1°C).
The gain determines the max. temperature. The adjustment occurs via a factor and
is calculated as follows.
Max. temperature [°C] = An.44 + (100% / An.43)
Example
