Product Description:

The CSB01.1C-SE-ENS-EN2-L2-S-NN-FW is a control section from Bosch Rexroth Indramat and belongs to the CSB Drive Controllers series. As a plug-in drive controller section, it coordinates power stages and fieldbus communication to regulate servo axes in automated machinery. By pairing with a compatible power module, the unit issues motion commands, processes encoder feedback, and exchanges real-time status with plant networks. This arrangement places the axis control functions in the control section while the companion module handles power conversion.

The section is designed for an axis count of 1, so all internal resources are dedicated to a single drive. Its base electronics draw 8 W, which helps limit cabinet heat when the axis is idle. Command and diagnostic signals reach the controller over SERCOS II, and a fast backplane transceiver supports a network transfer rate of 16 MBaud for synchronized interpolation cycles. On the machine side, the unit provides 8 digital inputs for limit switches or probes and 3 digital outputs for contactors, brakes, or status lamps. These channels let the application respond directly to machine events without requiring an additional I/O card for basic signal handling.

Position feedback enters through two encoder ports. The primary ENS interface supplies a constant voltage of 11.6 VDC, which supports SinCos transducers while maintaining stable sensor power over connected cable runs. The secondary EN2 port accepts EnDat 2.1, 1 Vpp, or 5 V TTL signals and supplies 5.0 VDC to the sensor, allowing compatibility with several common feedback types. This dual-channel arrangement supports redundant feedback or mixed feedback configurations. Functional safety is handled by integrated Safe Torque Off, which disables gate pulses when its control line receives 24 VDC, and the low enabling current allows use with light-current safety relays.
