AC30 series General Purpose I/O Option
Motor Thermistor (7004-01-00, 7004-02-00 and
7004-03-00)
The motor thermistor input provides a means of monitoring motor
temperature in order to protect the motor from a potentially damaging high
temperature.
By default the drive will trip if the motor exceeds a user-defined
temperature threshold thereby preventing the motor temperature from
rising further.
