Kollmorgen servo motor overload repair steps
1.Lock and mark out the main circuit breaker;
2.Use a magnetoresistive meter to detect the insulation resistance of servo motor wires and reluctance coils between T1, T2 and T3 leads and ground
3.Test the "T" to the Lenz servo motor with an ohmmeter to detect continuity and ohms between the windings from A to B, B to C, and A to C. The resistance between each resistor should be between 1 or 2 ohms;If the ohmic readings are significantly different or not continuous;Go to the motor circuit breaker box, close, and test the continuity and resistance of the "T" line again;If the reading is good, the problem is with the wiring from the servo motor controller to the isolator
4.Disconnect and tighten all three wires on the switch, check the three wires;Go to the controller and check the continuity between A to C, B to C, A to C;One or more wires are disconnected or grounded;
5.Pull all the new wires from the controller to the servo motor to disconnect the switch. Problems caused by any reason can damage other wires. Please replace all wires.
6.If the problem is on the servo motor side of the disconnector, please open the motor junction box and disconnect the motor
7.Check the ground resistance of the motor with a megahertz meter. If the reading is less than 500,000 ohms, the motor must be grounded and replaced;Test ohms between motor windings with ohmic meters A to B, B to C, A to C, and the readings should be within 1 2 ohms. If the readings show an open circuit or a significant ohmic difference, replace the motor;
8.If the motor test reading is good, test the continuity and ground resistance of the motor wire between the isolator and the motor junction box. If the reading is not good, replace the cable;
9.If all readings are normal, reconnect the motor and return to use it after unlocking. The problem may be mechanical in nature;Motor overload caused by chain, belt, bearing damage, gearbox failure, or power failure.
