Product Description:
The CSB02.1A-ET-EC-NN-L3-NN-NN-AW is a single-axis drive controller produced by Bosch Rexroth Indramat within the CSB Drive Controllers series. Designed for servo and induction motor regulation in automated machinery, the unit coordinates current, speed, and position loops while exchanging data with higher-level PLCs through integrated Ethernet interfaces. Its role in an automation cell is to close the electrical drive circuit, translate command words into precise inverter pulses, and feed back status information for synchronous multi-axis motion.
The controller accepts one analog command channel scaled at ±10 V, allowing direct velocity or torque references from process hardware. It has 7 digital inputs that support enable, quick stop, and mode changes. Within the power stage, the current loop closes every 125/62.5 µs, so motor phase current follows reference steps with limited delay. Communication to plant networks uses Multi-Ethernet with the electrical layer conforming to 100Base-TX, ensuring fast messaging over Cat-5e cabling. Pulse generation for the inverter can be set to 2, 4, 8, 12, or 16 kHz, balancing switching losses and noise.
Complementary timing loops finish the control hierarchy: the speed regulator updates at 250/125 µs and the position loop at 500/250 µs, permitting tight contour accuracy when the application demands it. Safe machine shutdown is supported by the integrated STO (Safe Torque Off) function, which removes drive energy without external contactors. Network connection is provided through an RJ-45, 8-Pin socket, and the internal web server supports diagnostics. The integrated operating panel is ADVANCED, providing parameter entry and oscilloscope traces on a small front display. One configurable I/O channel, two probe inputs, and a single relay output supply auxiliary feedback, giving machine builders flexibility for home switches, latch events, or fan control without extra PLC cards.
