Product Description:
The CSB02.1B-ET-EC-EM-NN-NN-NN-AW is a drive controller designed by Bosch Rexroth Indramat for the CSB Drive Controllers series. Mounted next to servo inverters, it closes the current, velocity, and position loops that govern modern production machinery, translating PLC commands into precisely timed motor signals. Integrated local inputs, outputs, and network ports allow the device to coordinate motion, gather feedback, and forward status data, making it a core automation component rather than a stand-alone PLC.
It is powered from a 24 V DC control supply and draws only 17 W under base load, reducing heat generation inside compact electrical enclosures. The internal DSP executes the current loop every 62.5 µs, while the velocity regulator refreshes at 125 µs so transient speed errors are corrected before they spread to the mechanics. Differential converters provide 3 analog input channels that can accept torque or speed references, and two analog outputs return measured values for scope-based tuning. Five assignable digital I/O lines supplement the two dedicated fault contacts, enabling application-specific functions without extra interface boards.
The Multi-Ethernet interface handles SERCOS III, EtherNet/IP, and PROFINET telegrams in a 250 µs communication cycle, letting the drive synchronize with high-speed PLC tasks. A multi-encoder interface accepts TTL, Hiperface, or EnDat feedback, and encoder emulation is included for legacy axis cards. Position corrections are calculated every 250 µs to match the network pace. The module offers 11 dedicated digital inputs for home, limit, or probe triggers, while three optional slots accommodate extra safety or fieldbus cards. An onboard relay can switch loads up to 1000 mA at 30 V, reducing the need for external contactors when signaling brakes or clutches. The network ports carry diagnostics and motion commands on a single cable.
