Product Description:

Kollmorgen motors manufacture a range of permanent magnet motors. They make sure several quality and high performance industrial motors are made available in varying sizes and several package types. The unique features of their motors make it suitable for a wide range of demanding application requirements in industrial motors. They are responsible for developing high technology and high performance industrial machines including direct drive linear and rotary, brushless servo motors, and gear motors. The AKM synchronous servo motors are one of the Kollmorgen's high quality and high performance products.

The AKM synchronous servomotors are specially designed for heavy industrial duties such as drives for industrial robots, textile, packing machinery, as well as machine tools. The AKM42G-EKCN2-00 is one of the most significant AKM series designed to perform these vital industrial operations better and faster. The AKM42G-EKCN2-00 has features such as 84mm flange size, rotor length of 2 and winding type G that makes it suitable for its purpose. It makes use of rotatable angular connectors, alternative IEC flange standard, and open keyway to ensure its suitability for industrial purposes. The feedback system is composed of comcoder with 2048 PPR having a standard customization.

At 120^oC, the AKM42G-EKCN2-00 has holding torque of 6Nm and electric power of 12.8W. It has a round angular, 4+4 poles power connection, 17 poles round angular encoder connection, and 12 poles round angular resolver. These features are to ensure that the machine functions with low harmonic distortion and smooth performance. It has a rated speed of 3500rpm, a rated torque of 2.90Nm, and a rated power of 1.06Kw at 230V. It can move up to 6000rpm at 400V, ensuring users always have enough power. The effective sinusoidal value also known as the peak current is almost equal to 4-times the rated current. Likewise, AKM42 is optionally available for holding brakes.

Ordering Code

Fault Code	What it means
F301 – Motor overheated	Internal thermal sensor says the windings or case are above the safe limit.
F302 – Over-speed	Actual shaft speed has exceeded the VL.THRESH limit.
F305 – Brake open-circuit	Drive cannot pull ≥ 200 mA through the motor-brake coil when energized.
F308 – Voltage exceeds motor rating	DC-bus voltage is above the motor’s name-plate limit.
F402 – Analog signal amplitude fault	Resolver or sin/cos feedback amplitude is out of range.
F403 – EnDat communication fault	Serial feedback packets not received within timeout.
F404 – Illegal Hall state (111/000)	Hall sensors show an impossible pattern.
F418 – Primary feedback power-supply fault	5 V / 7 V supply to encoder/resolver has collapsed.
F421 – Resolver sensor fault (SFD)	Motor’s built-in resolver self-diagnostics reports an error.
F312 – Brake released when it should be applied	Mechanical brake unexpectedly disengaged during “brake-on” state.

Error / Symptom	Probable Cause(s)	Recommended Troubleshooting Steps
Drive will not enable (motor never energizes)	ENABLE hardware line not asserted; “software enable” bit false; safety relay open	Verify 24 V logic supply and ENABLE signal are present in the AKD/other drive. Check PLC/fieldbus command word for the software-enable bit.
Motor fails to rotate after enable	Brake still clamped; mechanical jam; set-point cable fault	Confirm holding-brake release voltage through the motor’s brake connector. Check for shaft obstructions or load binding. Inspect set-point/command wiring for breaks.
F20x / “Over-current” fault	Shorted phase lead; sudden load spike; acceleration ramp too aggressive	Measure phase-to-phase insulation and repair wiring. Reduce load inertia or update motion profile (longer accel).
F14x / DC-bus over-voltage	Regen energy on rapid decel; mains voltage high	Lengthen decel ramps; activate or size regen resistor pack; verify mains voltage.
F15x / DC-bus under-voltage	Mains drop or loose supply lead	Measure incoming VAC; tighten terminals; check fusing or breakers feeding the drive.
F402 “Encoder/feedback fault”	Resolver/encoder amplitude out of range; mis-alignment; broken feedback cable	Scope resolver/encoder signals at X10. Realign feedback hub; replace or re-terminate cable if noise present.
Phase loss / phases swapped (motor chatters or hums)	One motor phase open or incorrectly sequenced	Verify U-V-W continuity and tighten power leads. Swap any two phases to correct rotation if sequence wrong.
Excessive vibration & noise	Bearing wear; rotor imbalance; shaft-to-load misalignment	Inspect & replace worn bearings; align coupling; balance rotor if needed.
Position drift / hunting oscillation	Encoder noise; tuning gains too high; inertia mismatch	Check encoder counts manually; lower servo gains; verify load inertia ratio.
Over-temperature trip / smoke or burning odor	Blocked airflow; excessive duty cycle; stator short	Clean cooling vents; add forced air if motor case exceeds 120 °C. Run a winding-insulation (megger) test; schedule service if insulation is <1 MΩ

Frequently Asked Questions about AKM42G-EKCN2-00:

Q: Can the AKM42G-EKCN2-00 be driectly installed without a control cabinet?

A: The housing of the AKM42G-EKCN2-00 is designed to prevent the interference of solid materials and water splash directed at the motor from any angle. This high protection enables the motor to operate effectively without the need for an additional control cabinet.

A: As soon as the order you place for the AKM42G-EKCN2-00 motor is processed and confirmed, the produced is shipped within 2 days. Our delivery operation is handled by trusted partners such as UPS, DHL and Fedex.

Q: What does the coating on the AKM42G-EKCN2-00 protect the motor against?

A: The black coating on the AKM42G-EKCN2-00 is designed to prevent the rapid deterioration of the motor that can be caused by corrosive substances such as dilute acids, sea water, seawage and mineral oil. The coating helps the motor to remain in prestine condition for a long time.

Q: If I request for repair operation on the AKM42G-EKCN2-00, how quickly will it be completed?

A: Generally, rapairs operations on the AKM42G-EKCN2-00 are completed within 7 to 14 days. Customers can however opt for the 4 days repair option at a small additional fee.

Q: Can the AKM42G-EKCN2-00 be used in food production operations?

A: The black coat covering the AKM42G-EKCN2-00 makes the motor unsuitable for food processing and washdown operations. Customers can however order for special variations of the motor that meets the strict hiygine regulations which suitable food processing operations.
