Product Description:
For use in industrial automation, Bosch Rexroth offers the KDA 2.1-150-3-API-U1 servo drive module. This Series 2 module has a 150 A rated current and is based on Design Version 1. The servo drive module is designed for aerospace, satellite control, and driving motors that take in commands and turn them into accurate commands.
The KDA 2.1-150-3-API-U1 servo drive module allows precise motor regulation by operating with an analog speed command value of ±10 V. A spindle or another motor with auxiliary and synchronous inputs can provide feedback via the module's auxiliary encoder input. The auxiliary interface receives its output from an incremental encoder. The heatsink blower in the module is powered by an alternating current (AC) supply source with a voltage rating of 115 V and a frequency range of 50 to 60 Hz. In order to keep performance reliable under specified operating conditions, certain environmental standards are critical. For thermal stability, the cooling mechanism relies on forced cooling via a heatsink blower. A DC bus voltage of 300 V is specified. The servo drive is fully functional within an ambient temperature range of +5 °C to +45 °C.
Under Humidification Class F, the KDA 2.1-150-3-API-U1 servo drive module satisfies DIN 40 040. It is essential to maintain a maximum relative humidity of no more than 70% during the wettest month to avoid condensation. When the temperature rises over 45 °C, a linear derating increases until the temperature reaches 55 °C, after which the drive value drops to around 80%. The module supports industrial automation and provides dependable drive control. The drive's technical configuration and compliance standards make it a dependable component of automation systems.
Frequently Asked Questions about KDA 2.1-150-3-API-U1:
Q: Does KDA 2.1-150-3-API-U1 support auxiliary encoder input?
A: Yes, the module includes an auxiliary encoder input. It allows spindle or second motor feedback that enhances synchronization and improves control flexibility in applications.
Q: Why does KDA 2.1-150-3-API-U1 need forced cooling?
A: Forced cooling by the heatsink blower regulates heat buildup effectively. It maintains operational safety, protects internal components, and ensures continuous performance under specified load conditions.
Q: How does KDA 2.1-150-3-API-U1 manage high ambient temperatures?
A: The drive supports full operation up to +45 °C. Above this, performance derates linearly until +55 °C, where it maintains around 80% drive value.
Q: Why does KDA 2.1-150-3-API-U1 have an IP 10 rating?
A: IP 10 protection prevents solid object penetration over 50 mm. This ensures drive safety, avoids physical contact risks, and maintains reliable functioning under defined standards.
Q: Do environments affect KDA 2.1-150-3-API-U1 performance?
A: Yes, the product follows Humidification Class F limits. It functions in cold, moderate, and dry-warm climates with ≤70% humidity and strict no-condensation requirements.
