AZ series thermal protection

Postby om_tech_support_JT » Thu Oct 06, 2016 4:05 pm

Q: Does the AZ series products offer thermal protection for the motor? If so, how does it function and is there a way to customize it?

A: The AZ product is a closed loop stepper motor with an absolute mechanical encoder; also referred to as the ABZO sensor. The ABZO sensor uses ‘Magneto Resistance sensing’ method. It reads the change of electrical resistance in a magnetic field. This allows it to calculate the geometrical position of the motor shaft as well as the thermal condition of the motor.

Our AZ product does offer a motor overheat protective alarm which generates when the motor windings reach 85 degrees C [alarm code 26h]. The “motor temperature information” parameter sets the generation condition of the motor temperature information (INFO-MTRTMP). Setting range: 40 to 120 °C (104 to 248 °F); the default value is 85 degrees C.
