Product Description:
The CSH01.1C-PB-EN2-NNN-NNN-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat for use in the CSH Advanced Controllers series. Installed in an IndraDrive modular rack, this unit governs one servo axis by processing motion profiles, evaluating encoder data, and forwarding torque commands to the power stage. The control section handles the command side of the axis while the separate power stage supplies motor current. In industrial automation, it allows packaging, handling, and metalworking equipment to execute coordinated movement sequences while maintaining electrical isolation between the application program and the high-voltage inverter components.
Communication with upper-level PLCs is handled through PROFIBUS via a 9-pin female D-Sub connector, and the channel supports data rates up to 12 MBaud for cyclic process data and acyclic parameter access. Five 24 V digital inputs draw only 3 mA each, and the eight transistor outputs are rated for 24 V / 0.5 A, allowing direct actuation of miniature solenoids or indicator lamps. A relay contact rated at DC 24 V / 1 A can switch larger loads, and the same rating applies to the STO acknowledgment circuit. Service diagnostics use an 8-pin Mini-DIN RS-232 port that reaches 115 kBaud over cable runs up to 15 m. The module housing measures 241 × 49.5 × 103 mm, which supports dense multi-axis assemblies in shallow cabinets.
The integrated safety circuitry delivers Safe Torque Off, removing drive energy without mechanical delay. This function is certified to SIL3 / Cat. 3 PL e, so it can be connected to emergency-stop chains without additional hardware. STO control wiring uses the same voltage and current levels as the standard inputs, and its connector is a 9-pin D-Sub beside the fieldbus port. Position feedback is accepted through the primary encoder interface, which recognizes EnDat 2.1 / 1 Vss / TTL signals and allows the controller to close loops with either absolute or incremental transducers while keeping wiring topology consistent across different axis designs.
