Motor temperature measurement through the standard I/O
This section describes the temperature measurement of one motor when the drive
I/O terminals are used as the connection interface.
Motor temperature can be measured using P
t
100 or PTC sensors connected to
analog input and output.
WARNING!
According to IEC 60664, the connection of the motor temperature
sensor requires double or reinforced insulation between motor live parts and
the sensor. Reinforced insulation entails a clearance and creepage distance of 8 mm
(0.3 in) (400/500 V AC equipment).
If the assembly does not fulfill the requirement, the I/O board terminals must be
protected against contact and they may not be connected to other equipment, or the
temperature sensor must be isolated from the I/O terminals.
