Feedback Devices
Properly calibrating them accurately for top-flight performance and diagnosing problems in today's servo motors from Kollmorgen, Yaskawa, Siemens and Fanuc requires understanding of encoders, resolvers, AC and DC tachometers, and other feedback devices along with complicated drives, software, and feedback-to-controller cabling.
At Servotech, we inventory dozens of software programs and drives to match each manufacturer's motor and feedback configuration. We utilize more than 250 different feedback-to-controller cables. This equipment allows us to connect to, test, and repair feedback devices in the same manner as the manufacturer. Our equipment also insures the feedback devices are properly installed and aligned with the servo motor.
Do Your Feedback Devices Need Repair?
- • Have a spindle motor with a proximity sensor?
- • Does your motor have multiple feedback such as a
tachometer and encoder or multiple resolvers? - • Are your Hall effect sensors not working properly?
This is what we fix day in and day out. We can determine the proper output, test, and repair most any type of feedback device used in servo and spindle motors.
Servotech employs technicians who are properly trained in the repair of feedback devices along with the repair of servo and spindle motors. We strive to become the most efficient and reliable servo refurbishment repair facility in the industry so call 1-866-80SERVO today so we can assist you with your feedback device repair needs.
Feedback Repair
We repair most makes of encoders, resolvers, tachometers and other forms of feedback.
Encoders
Absolute or incremental, with or without commutation we can test, refurbish, or replace many types of encoders. We evaluate encoders in terms of output voltage per line, phase symmetry, and number of counts per revolution. Your encoders are back driven at max speed to insure they will perform to the manufacturers specifications. We also have the ability to decode serial information supplied by many new encoders.
Resolvers
We have the technology to test resolvers of any speed at any frequency. If your resolver requires repair we can rewind or replace it. We can also pot resolvers that are vulnerable to damage if necessary.
Tachometers
We can service and replace most AC and DC tachometers. All tachometers are evaluated in terms of voltage output per pre-determined rpm, polarity, and will have neutral checked when attached to its corresponding Servo motor.
