5.1.1 Servo Module, Drive, or Motor Troubleshooting Procedure
DANGER: This module has a voltage of 50 V or greater, NO contact should
be attempted before removing power. This especially includes separation
or insertion of the mating connectors or any contact with the Tool Changer
or its components. Arcing and damage will occur if this is not observed.
Remove power before attaching, disconnecting any cables or attempting any
maintenance of Tool Changer.
Complete the following steps in accordance with the customer’s energy control and electrical
safety practices or programs for isolating hazardous energy sources (i.e. electricity, air, etc.). The
following sequence is recommended for troubleshooting servo motor problems.
1. First examine all of the cables, cable connectors, and power sources for problems and correct as
necessary.
2. Use a known good set of cables (power and signal) to bypass the servo modules and directly
connect the drive to the motor.
3. If the motor does not operate properly with known good cables, the problem is in the drive or
motor. Troubleshoot these components using that manufacturer’s procedures.
4. If the motor operates properly, use the known good cables from step 2 to connect between the
servo drive and ATI master servo module. Use a second set of known good cables to connect
the Tool servo module to the motor.
5. If the motor operates properly, the problem is in the old cables which must be repaired or
replaced.
6. If the motor does not operate properly, the problem is in the servo module.
7. Examine the servo modules for damage to their electrical connectors and contact pins. Clean all
accessible surfaces, where necessary. Ensure that the spring pins on the Master side can move
freely and are not bound by debris. Clean the spring pins with contact cleaner to restore free
operation.
8. If the above steps fail to restore proper operation, contact ATI for service.
