Product Description:
The CSB02.1B-ET-EC-EP-S5-DA-NN-FW is a modular drive controller assembled by Bosch Rexroth Indramat within the CSB Drive Controllers series. It is intended to regulate servo and spindle axes, converting low-voltage logic into high-speed command sequences for industrial automation cells. The device combines encoder power, resolver excitation, analog conversion, and Ethernet communication so that motion tasks, safety interlocks, and diagnostics can all be processed by a single rack-mounted card. By centralizing these functions, the controller reduces panel space and supports coordinated operation between motion hardware and higher-level control equipment.
Control electronics draw a nominal DC 24 V supply and dissipate only 17 W at base load, keeping cabinet temperature rise low. Initial energization is limited to <5 A of inrush, which eases sizing of upstream fuses. The integrated DA interface exposes 2 AI, 2 AO, 6 DI, 2 DIO, and 6 DO, while voltage inputs use a 300 kΩ input resistance and are digitized at 14 bit resolution. Each analog output settles within 250 µs, supporting tight motion loops. These mixed-signal channels let the controller read process values and send command signals to surrounding machine devices during normal operation. Pulse command handling remains consistent for widths as short as 1 ms, while the logic can sample resolver angles and incremental feedback without cycle overrun.
Network communication is provided through 2 Ethernet ports that observe the IEEE 802.3 standard, enabling daisy-chain or ring topologies without external switches. The controller furnishes encoder supplies at 5 V or 12 V, both capable of delivering 500 mA, and total encoder power is capped at 6 W to protect the logic rail. Resolver feedback is excited with 10 Vpp at a carrier frequency of 8 kHz, yielding stable sine-cosine returns for precision angle tracking. This arrangement supports reliable feedback acquisition across machines that use different sensor types on adjacent axes. Combined with its digital I/O resources, the controller can coordinate axis commands and status monitoring across varied machine platforms.
