Product Description:
The DE-90287 servo cable is created by Kollmorgen. It is part of Kollmorgen Servo Cables series that includes an electrical cables best designed for connecting the servo motor to servo driver. This module is best suitable to use in industrial automation applications.
The DE-90287 servo cable works on the motors that have the power rating between 1.96 kW to 5.86 kW. Operating on such a high-power rating motor requires the servo cables conductors to have thicker cross section for handling higher currents effectively. These cables are designed for the servo motors that have rated speed in the range from 2000 to 6000 per minute. In order to ensure reliable and efficient operation the feedback frequency and EMI shielding requirements must be met. These servo cables can supply sufficient current required by the servo motor that generate torques up to 18.1 Nm. The peak current requirement it can meet is 56.5 Amps which the motor connected to it consumes. This module is highly effective to handle surges in current without degradation. With every one ampere supply of current the connected servo motors generate up to 3.70 Nm.
The DE-90287 servo cable has an excellent shielding that prevents the electromotive force from interfering with signal lines. The winding resistance of the motor ranges between 0.30 to 5.16 Ω for which the cables are designed. The winding inductance of the servo motor that the Kollmorgen Servo Cables supports ranges between 2.2-43.5 mH. It is compatible with the motors with the rotor moment of inertia from 17 - 40 kgcm². These cables have enough thermal stability that works on motors with thermal time constant between 20-35 min.
Frequently Asked Questions about DE-90287:
Q: What is the purpose of EMI shielding in DE-90287 servo cable?
A: The EMI shielding in the DE-90287 prevents external electromagnetic interference from affecting signal transmission. This ensures accurate feedback and smooth motor operation.
Q: How does the DE-90287 support thermal stability for motors?
A: The DE-90287 supports motors with a thermal time constant of 20–35 minutes, providing excellent heat dissipation. This allows for reliable performance during long operational cycles.
Q: Why is the torque constant important in DE-90287 cables?
A: The torque constant of 0.66–3.70 Nm/A indicates how much torque is generated per ampere of current. This ensures that the motor operates efficiently under varying loads.
Q: How does the DE-90287 manage high peak currents?
A: The DE-90287 can handle a peak current of up to 56.5A, ensuring stability during sudden current surges. This prevents performance degradation and maintains reliable motor operation.
Q: How does static friction torque relate to servo cable design?
A: The DE-90287 supports motors with static friction torque between 0.05 and 0.2 Nm, ensuring consistent performance. This helps avoid motor stalls during fine adjustments.
