Product Description:
KDA 2.1-150-3-A00-U1-115 is created by the leading manufacturer Bosch Rexroth Indramat within the KDA Spindle Drives lineup. This lists a rated output current of 150 A which enables sustained spindle torque delivery for heavy machining tasks. Its axis design corresponds to single axis and simplifies integration into machines that require a single main spindle. Its wide supply compatibility accepts a rated line voltage of 3 × 380–480 V AC ±10% and permits use on standard three phase industrial mains.
Dual mains compatibility covers 50/60 Hz with ±2% tolerance to keep control loops stable across regional frequencies. Device’s auxiliary electronics operate from a control voltage of 115 V AC, powering control circuits and any mandated blower supply. The inclusion of standard analog and digital communication interfaces provide conventional signal paths for speed and status exchange. Air-cooled operation removes heat by airflow which limits internal component temperature rise without added liquid circuits. Enclosure type IP 20 denotes protection for indoor cabinet installation and requires a cabinet or control enclosure for environmental safety.
This Indramat’s unit KDA 2.1-150-3-A00-U1-115 further specifies external dimensions of approximately 465 mm × 483 mm × 255 mm, thus defines the cabinet cutout and required clearance for installation. The drive’s mass is approximately 42 kg and it demands appropriate handling equipment and secure mechanical support during mounting. Cabinet mounting is the indicated installation method which secures the drive inside a control enclosure for safe operation. The device’s built-in protection features include overcurrent, short circuits, overvoltage, undervoltage and excessive temperature which interrupt fault conditions and preserve internal circuits.
Frequently Asked Questions about KDA 2.1-150-3-A00-U1-115:
Q: How much does KDA 2.1-150-3-A00-U1-115 weigh and what does that imply?
A: The weight is approximately 42 kg and requires secure fixing points and appropriate lifting equipment. Installation procedures must account for the weight during mounting and servicing.
Q: What mounting method is specified for KDA 2.1-150-3-A00-U1-115 motor?
A: The intended mounting for this unit is cabinet mounting. This secures the module inside an enclosure for protection and wiring access.
Q: How does KDA 2.1-150-3-A00-U1-115 protect against overcurrent?
A: The drive includes overcurrent protection which trips when current exceeds safe limits to prevent damage. It isolates faults and preserves power stage components.
Q: How does KDA 2.1-150-3-A00-U1-115 handle short circuit events?
A: The feature of short circuit protection is integrated into the drive. The system detects and interrupts short circuit conditions rapidly. This limits fault energy and prevents further damage to the drive and cabling.
Q: How does KDA 2.1-150-3-A00-U1-115 respond to overvoltage conditions?
A: The module provides overvoltage protection that senses voltage excursions above the specified range and disconnects or brakes the drive. This prevents component stress from excessive supply voltages.
