Product Description

The KDA1.1-100-300-W1-220V main spindle drive by Bosch Rexroth comprises D-Sub connectors that must be secured in place when the drive is in use. This spindle depicts the ground connection of the associated motor. The product is installed in its control closure using the M1-KD mechanical accessories kit and the blower. The device must be mounted only vertically. This unit incorporates forced cooling by the heatsink blower. It operates motors with up to 25 HP at the output shaft. This drive supports positioning and unrestricted four-quadrant operation. The product has a speed range of 0 to 8000 rpm. This device renders an accurate speed control because of a microprocessor based digital velocity loop. The unit is known for its high stability and stiffness. It has a power bridge for converting the DC bus from the power supply to a rotating three-phase power supplied to the AC spindle motor. The drive also encompasses circuitry to accept current commands and determine how much power should be supplied to a specific phase of the motor. This unit can be adapted to different motors using the parameters stored in the EEPROM memory of its programming module. The drive is monitored during its operation by an inbuilt microcomputer. It delivers high-quality C-axis operation. The product has no protection against deliberate penetration such as by hand. This device has a compact construction combined with a robust design. The unit may encounter snapping of its studs if their maximum tightening torque is not ensured. Its programming module should not be pulled out when the power is on. This spindle drive is not recommended to be repaired by the user.
