internal resistance of the digital input from the analog input and calculates the PTC
resistance.
Note: RIIO-01 or BIO-01 is required for the analog input. By default, RIIO-01 is
provided with the ACS560 drives.
Example settings
The parameters are set as follows for monitoring the temperature with PTC sensors:
WARNING! IEC 60664 requires double or reinforced insulation between live
parts and the surface of accessible parts of electrical equipment which are
either non-conductive or conductive but not connected to the protective. Obey
the electrical planning guidelines for implementing the motor temperature sensor
connection. If you ignore them, injury or death, or damage to the equipment can
occur
For wiring of the sensor, refer to the drive hardware manual.
Make sure that the DI used is not configured to any other use in the drive control
program.
Temperature monitoring using Pt100 sensors
1…3 Pt100 sensors can be connected in series to an analog input and an analog
output.
The analog output feeds a constant excitation current of 9.1 mA through the sensor.
The sensor resistance increases as the motor temperature rises, as does the voltage
