Motor Temperature Sensor (X31A/B)
The FC2 provides up to 12 inputs for motor protection (PTC/NTC). One individual input
is provided for every spindle. The inputs must be connected correspondingly.
The input motor protection (PTC/NTC) allows for example connection of PTC resistors
that are often used in three-phase motors for temperature monitoring. Connecting
pressure control devices and controllers for coolant or lubricant that are conceived as
switch contacts is also possible.
If the connected value is higher than the programmed value, the frequency converter
triggers a higher-ranking stop process. During this process the motor is decelerated
until the speed value is zero. An error message is saved and displayed. The error
message is acknowledged via the reset functions.

The number and position of the running spindles is selected via the connector X32.
One specific input is assigned to every spindle for spindle selection. The frequency
converter calculates the value for current limitation on the basis of the number of
selected spindles.
