Motor Thermistor Connections
This input (terminal X16) is provided to detect over-
temperature in motors fitted with an internal thermistor.
There is no polarity to the thermistor connections.
IMPORTANT This input provides "Basic" insulation only to the SELV
control circuits and assumes the motor has "Basic"
insulation to the windings/mains circuits.
The thermistor type supported is PTC `Type A' as defined
in IEC 34-11 Part 2. The drive uses the following resistance
thresholds:
Rising temperature trip resistance:
Falling temperature trip reset resistance:
If the motor is not fitted with an internal thermistor, you should disable the
thermistor trip function either by setting INVERT THERMIST to be TRUE, or by
linking the thermistor terminals.
