Product Description:

The CSB02.1B-ET-EC-EM-S5-NN-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat within the CSB Drive Controllers series. It acts as the interface between a PLC and multiple servo axes, generating real-time current and velocity commands while supervising the safety layer required in automated assembly cells, packaging machines, and material-handling stations. All internal electronics are powered from a DC 24 V control supply, which simplifies cabinet power distribution and keeps logic isolated from the mains circuit.

This controller acquires analog feedback with a resolution of 11 Bit for current loops and 13 Bit for voltage loops, allowing tight gain tuning and low quantization noise. When the application needs an analog reference, the device produces setpoints in steps of 24 mV/Incr, so drive outputs can be trimmed without external converters. For deterministic data exchange with supervisory systems, it offers Multi-Ethernet communication that supports several real-time Ethernet protocols through a single port. Safe Motion S5 is integrated, and this function set supervises speed, direction, and standstill without additional relays.

The power stage is protected against startup transients, with inrush current staying below < 5 A and limited to a pulse of 1 ms, reducing stress on fuses and auxiliary supplies. A probe pulse width of 4 µs gives the position-measurement interface enough bandwidth to capture fast encoder signals generated by high-speed axes. Digital safety inputs meet the IEC 61131 Type 1 category, so enabling devices can be wired directly without signal converters. Two onboard change-over relays can switch up to 1000 mA at 30 V, providing field-isolated contacts for brake release, contactor drive, or status signaling. The Safe Motion S5 channel works with these relays to execute controlled stops or hold functions during maintenance.
