KOLLMORGEN IDC EC Series Electric Cylinder Configuration and Application Guide

Structural rigidity: The supporting structure must be able to withstand three times the maximum load of the cylinder body and minimize deformation to the greatest extent possible.

Accurate alignment: The motion axis of the cylinder block must be strictly parallel to the movement trajectory of the load. The manual provides a step-by-step calibration process for different installation methods (such as front flange alignment and side ear alignment), effectively eliminating stress through the method of "loosening first, then running several cycles without load to automatically align the cylinder body, and finally tightening".

Rod end connection torque control: When connecting the load to the rod end, it is strictly prohibited to exceed the maximum torque calibrated on the thrust pipe (such as EC3 being 65 ft lbs clockwise), otherwise it will damage the internal guide flange. The provided hexagonal plane should be used to fix the thrust tube and prevent it from rotating.

End of travel protection: It is strongly recommended to install position sensors (such as mechanical reed PSR series or Hall effect PSN series) as electronic limiters, rather than relying on physical hard stops inside the cylinder block. The sensor should be installed on the inner side sufficiently away from the physical endpoint to reserve deceleration distance and prevent high-speed impact.

Key application considerations and environmental adaptability

When deploying EC electric cylinders, engineers need to evaluate the following key factors:

Cylindrical load and critical speed: These are the two core limitations of the screw system. The limit of cylindrical load decreases with the increase of stroke, and once exceeded, it will cause the screw to buckle. The critical speed is the speed threshold that triggers screw resonance, and continuous overspeed operation can cause severe vibration and damage. The manual provides detailed tables for reference.

Work cycle and heat dissipation: In extreme working conditions such as high speed, high load, or frequent start stop, attention should be paid to the thermal management of the motor and drive system. If necessary, it is necessary to install heat dissipation devices or reduce the working cycle.

Environmental protection: Standard IP54 protection can prevent dust and splash water. In dusty, humid, or low-temperature (<2 ° C) environments, the ventilation pipe joint provided with the cylinder must be installed. For environments with corrosive liquids or abrasives, it is recommended to use an IP65 protective cover (- PB) or an additional designed protective shell.

Optional functions and daily maintenance: expanding capabilities and ensuring lifespan

The EC series offers a wide range of optional features to enhance system performance:

Brake: Provides two options: screw brake (- BS) and motor shaft brake (- BM), used to maintain the power-off position and prevent load backdrive (reverse drive). Please note that this is a static holding brake and cannot be used for dynamic braking.

Feedback device: The rotary encoder (- EMK/- EM) can provide position feedback of the motor shaft for closed-loop control. The linear potentiometer (- L) directly measures the linear displacement of the thrust tube, providing an analog position signal, especially suitable for simple control systems that require absolute position feedback.

Regular maintenance: In applications with high loads and high work cycles, regular maintenance is crucial. The manual suggests that for EC2/EC3 with trapezoidal lead screws, the lead screws need to be re lubricated every 200000 inches (approximately 5080 kilometers) of operation; For other ball screw models, this cycle is 1 million inches. The maintenance includes checking/adjusting the belt tension (deflection should be less than 3.17mm), lubricating the gears, and correcting the mesh clearance between the motor small gear and the intermediate gear (maintaining a back clearance of 0.076-0.203mm).

System integration and troubleshooting

The manual contains detailed troubleshooting guidelines, categorizing common issues into different types such as abnormal noise, abnormal movement, inaccurate positioning, thrust pipe problems, component damage, etc. It also lists possible causes and remedial measures (such as on-site adjustments or factory repairs). This provides a systematic tool for on-site engineers to quickly diagnose problems. At the same time, the manual also guides users on how to install the motor provided by the customer, emphasizing the steps of shaft hole cleaning, use of Loctite adhesive, belt installation, and final alignment.
