Product Description:

The CSB01.1C-PL-ENS-NNN-NN-S-NN-FW control section is manufactured by Bosch Rexroth Indramat as part of the CSB Drive Controllers series. It plugs into a power section to form a modular servo drive that sequences motion axes and handles field-level I/O inside automated machinery. By converting encoder feedback and discrete signals into drive commands, the unit coordinates velocity, torque, and position loops for industrial robots, packaging lines, and material-handling stations.

The module draws a base load of 8 W from the cabinet supply and operates on a control voltage of 24 VDC. At startup, it can pull an inrush current of 4.5 A for 110 ms, so the upstream supply must tolerate this transient without tripping. Each of the sixteen digital inputs registers a logical high when at least 15 V is present, allowing direct wiring of standard sensor outputs. Encoder lines terminate in an input circuit rated at 120 ohms, which matches typical RS-422 differential drivers and helps limit signal reflections. Sixteen transistor digital outputs are available, and the master communication interface is a parallel port that exchanges command words with higher-level controllers at high speed.

Each digital output can source up to 500 mA and absorb inductive energy of 400 mJ per switching event, supporting direct connection to pneumatic valve coils and contactor relays without external suppressors. The encoder connector provides a regulated supply of 11.6 VDC for incremental or absolute feedback devices, removing the need for a separate sensor power rail. These drive-side resources reduce cabinet wiring and enable decentralized signal processing close to the motor. The low internal consumption limits heat generation, so standard convection inside an IP20 rack is usually adequate.
