Product Description

The KDA2.1-150-300-AP0-U1/115 main spindle drive from Bosch Rexroth should be put to operation only with the manufacturer's drive controllers and motors. This spindle drive comes with an auxiliary encoder input for second or spindle motor feedback. The product can be used for spindle positioning with C-axis operation. This device must be removed from the control cabinet after removing and releasing the DC link bus rails and other connections along with releasing its stud bolts at the top and bottom. The unit should be held by its long studs on either side when it is pushed into the control cabinet. This drive can be operated in humid areas like workshops and in dry-warm, moderate, and cold climates. This product is protected against penetration by objects that have a diameter higher than 50 mm. The device can be assembled only in a control enclosure that adheres to DIN 40 050 specifications. This unit comprises the terminals for its motor connection and DC bus connection on its X8 connecting point. Its load factors must be multiplied when the ambient operating temperature and installation altitude are exceeded. The drive should have no condensation on its surface. This product features its auxiliary encoder input at the X5 connector. The device also has a plug-in connector at the bottom for its readymade cable. This drive emits heat through the heatsink mounted on its rear and over the air vents in its housing. The unit portrays an internal heat loss as well as an external heat emission based on the workload. It must be ensured that the average relative humidity during its operation in the most humid month of the year is not more than 70%. This product features a contamination of its heatsink because of very dirty cooling air. The spindle drive switches itself off with insufficient heat.
