Product Description:
Bosch Rexroth Indramat manufactures the KDA 3.2-100-3-L0S-W1 AC main spindle drive. The SERCOS interface allows for accurate speed control, which is included in the AC main spindle drive. The spindle drive is compatible with industrial automation applications and operates on 100 A and 300 V. A heatsink fan is used for forced cooling, and the drive has a serial RS-232C interface.
With dimensions of 525 mm in height, 390 mm in width, and 355 mm in depth, the KDA 3.2-100-3-L0S-W1 AC main spindle drive offers a compact structure. The heatsink measures 160 mm wide without the 25 mm deep air duct and 185 mm with the duct. The mounting hole spacing of 160 mm vertical and 345 mm horizontal ensures accurate installation alignment. The height of the blower unit increases from 110 to 125 mm when the protection barrier is installed. The blower measures 80 mm from the enclosure, 169 mm wide, and 88 mm deep. The heatsink duct and the air duct have the same width of 185 mm. To accomplish complete airflow distribution, raise the blower and mounting frame to a height of 490 mm. The total weight is 5.9 kg, which includes the 1.7 kg mounting attachments and the 4.2 kg blower unit.
With the KDA 3.2-100-3-L0S-W1 AC main drive user may power a 50-60 Hz heatsink fan with an AC supply voltage of 220 V. During prolonged duty, the blower's construction guarantees efficient forced cooling, which minimizes overheating. The 390 mm width and 345 mm horizontal mounting distance define the AC main spindle drive's design and assure strong positioning. For incorporation into regulated drive assemblies, the AC main spindle drive satisfies all electrical and dimensional requirements.
Frequently Asked Questions about KDA 3.2-100-3-L0S-W1:
Q: Why does KDA 3.2-100-3-L0S-W1 use forced cooling?
A: Forced cooling with a heatsink fan maintains a regulated temperature. It prevents the drive from overheating, which ensures stable operation. Continuous airflow improves reliability during high current output at 100 A.
Q: Does KDA 3.2-100-3-L0S-W1 support additional encoder input?
A: The spindle drive does not include an additional encoder input. Control accuracy is instead managed by the SERCOS interface that defines precise speed regulation.
Q: How does KDA 3.2-100-3-L0S-W1 utilize the RS-232C interface?
A: The serial RS-232C interface provides a connection for communication. It enables parameter adjustments and monitoring that integrate the drive into broader system architecture for controlled operation.
Q: Why do mounting holes in KDA 3.2-100-3-L0S-W1 measure 345 mm?
A: The 345 mm horizontal mounting distance ensures stability. It aligns the drive precisely that supports balanced load distribution and vibration control within installation assemblies.
Q: Does KDA 3.2-100-3-L0S-W1 require a specific blower size?
A: The blower has a height of 110 mm. It ensures consistent airflow, and when combined with the mounting frame, provides a total cooling height of 490 mm.
