Product Description:

Kollmorgen is a leading provider of motion systems and components. Their products include servo motors, drives, and automation platforms. They serve diverse automation industries globally.

The akm54k-accnr-00 is one of the various servomotors manufactured by Kollmorgen that operates with a SERVOSTAR digital servo amplifier. The motor features Class F insulation according to DIN EN 60034-14 specifications. The akm54k servo motor features a protective category of IP 65 and encompasses an electrically isolated PTC that is fitted into the monitoring system present in the servo amplifier. The motor is intended to operate between an ambient temperature range of +5?C to +40?C. The motor offers a standstill torque of 14.4 Nm while consuming a standstill current of 9.7 A. The motor supports an IM B5 basic mounting style. The cylindrical shaft end at the A-side is used for power transmission. The thermal time constant for the motor is 31 minutes and the torque constant value is 1.50 Nm/A. The model incorporates a three-phase winding. The akm54k servo motor must be protected from unacceptable stress and care should be taken to ensure that the insulation clearances do not get changed during transport.

The motor akm54k-accnr-00 generates a peak torque of 38.4 Nm while consuming a peak current of 29.2 A. The device tends to experience a high radial force when it is driven by toothed belts or pinions. The motor makes use of a standard resolver for feedback. The position of the resolver is evaluated by the servo amplifier. The PTC of the motor has a temperature rating of 155?C+/-5%. The shaft and flange of the device are vulnerable during assembly as well as storage. This product (akm54k-accnr-00) is available on the Wake Industrial website.

Field symptom / AKD drive fault* Likely root cause First corrective action(s)
F219 “Motor over-temperature” within minutes Stator PTC hit ≈ 155 °C Reduce load, improve cabinet airflow, clean filters, check PTC leads on X9 
F226 “DC-bus undervoltage” during fast decel Mains dip or bleeder too small Lengthen decel ramp, check mains fuses, test DC-link capacitors 
F228 “Position/velocity deviation” after mechanics work Loose coupling or bad tuning Re-home axis, re-torque hub screws, rerun AKD auto-tune 
F229 Encoder quadrant error at random Resolver/Hiperface noise Inspect shield continuity, reroute feedback away from motor power pair 
Housing > 70 °C, no fault logged Cabinet airflow blocked Restore fan/A-C, keep servo drive heatsink < 55 °C
