Product Description:
The KDA 3.1-150-3-A00-W1 Drive from Bosch Rexroth Indramat is specified for accurate spindle regulation in automated processes. The design of the drive supports efficient energy conversion for extended operation. The construction maintains stability across industrial environments where reliability is essential.
The KDA 3.1-150-3-A00-W1 spindle drive has a rated current of 150 A. The current rating supports sustained torque delivery which prevents instability during heavy cutting or machining loads. The command type for speed is analog. Analog control provides smooth input response and simple adaptation to automation controllers. The defined speed command value is ±10 V. That voltage window secures accurate drive modulation within the required operating limits. Cooling is active which maintains winding temperatures within safe boundaries and prevents premature derating. The blower supply source is AC and this AC-driven blower ensures consistent airflow without the need for conversion stages. The supply voltage for the heatsink blower is 220 V. That voltage level aligns with auxiliary power networks in industrial settings and provides reliable fan performance. The blower works within a frequency range of 50 to 60 Hz which guarantees compatibility across regions while maintaining uniform airflow over the heatsink.
The KDA 3.1-150-3-A00-W1 spindle drive tolerates storage and transport conditions from –25 to +85 °C. Such a wide range protects the product during handling and long-term warehousing. Installation is permitted up to 1000 m above sea level without output reduction. This capability allows operation in elevated production facilities without loss of rated performance. Protection category IP10 per DIN 40 050 applies and it provides basic protection against accidental contact and supports use in cabinet enclosures. The complete structure of drive secures accurate spindle operation under defined environmental and electrical specifications.
Frequently Asked Questions about KDA 3.1-150-3-A00-W1:
Q: How does the spindle drive control spindle speed?
A: It uses an analog ±10 V command input. This ensures smooth modulation of speed and quick adaptation to automation controllers.
Q: What benefits come from the 150 A rated current in the drive?
A: It provides steady torque delivery with its 150 A rating. This prevents instability during heavy cutting or extended machining cycles.
Q: How does the cooling system in the KDA 3.1-150-3-A00-W1 maintain stability?
A: The spindle drive relies on an AC blower operating at 220 V within 50–60 Hz. This system maintains consistent airflow for thermal regulation.
Q: Can the KDA 3.1-150-3-A00-W1 be installed at higher altitudes?
A: It allows installation up to 1000 meters above sea level. This ensures rated performance without derating in elevated facilities.
Q: What level of protection does the drive provide?
A: The KDA 3.1-150-3-A00-W1 complies with IP10 classification per DIN 40 050. It offers basic contact protection, making it suitable for use inside control cabinets.
