Product Description:
The KDA 3.1-050-3-LYI-U1 main spindle drive supplied by Bosch Rexroth Indramat comprises an incremental encoder output as its auxiliary interface. This drive’s heatsink blower delivers a forced air-cooling action. The product has high-resolution internal position control for C-axis operation. This device has no protection against water. The unit measures the rotor position over the complete speed range. It is associated with high stiffness, making it suitable for spindle positioning tasks. This drive’s full-speed control range can be achieved without a switching action using the SERCOS interface supported by it.
The product-related heat conduction takes place away from it when its back panel comprises the heatsink. This device’s operating temperature must never exceed 55 °C. The unit shouldn’t have condensation on its surface at any time. Its motor connection terminals feature a 5 Nm tightening torque. This drive’s vertical mounting is to be done with its grounding bolts facing upwards. The product’s control enclosure should comply with DIN 40 050 specification. This device is not safeguarded against deliberate penetration. The unit’s X12 connector is a plug-in terminal with three pins. It can be replaced without changing its blower as well.
This drive’s blower and its accessories weigh 5.9 kg. The product’s control cabinet has panel cutouts with a drilling pattern on the back panel. This device’s air vents and heatsink emit the heat generated. The unit’s external heat emission and internal heat loss are dependent on the workload. It turns off automatically with insufficient heat. This main spindle drive has a +24 V load voltage and a +/-15 V measuring voltage.
