Product Description:
The CSH01.1C-NN-ENS-NNN-NNN-S2-S-NN-FW control section belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. Within an IndraDrive modular inverter rack, this controller handles axis processing, field-level I/O, and safety supervision for servo and spindle drives used in material handling, packaging, and machining cells. By adding encoder processing and local signal conditioning, it allows multi-axis interpolation and real-time diagnostics without an external PLC.
The analog front end presents an input impedance of 160 kΩ, so external sources experience minimal loading when feeding position or torque references across the ±10 V range used by standard transducer outputs. Two scaled analog outputs are available, and each can source 5 V at 1 mA to report setpoint or actual values back to higher-level controllers. The section runs on a logic supply of 24 V DC, and at power-up it draws an inrush of 4 A before settling to nominal current. Twelve digital inputs accept 24 V, 3 mA, 1 µs signals, allowing fast capture of limit switches or probe triggers. Physical size is kept compact with a depth of 103 mm and a height of 241 mm, leaving space for cabling inside dense drive stacks.
On the output side, eight digital channels can switch loads up to 24 V, 0.5 A, and a separate relay contact is rated for 24 V DC at 1 A to isolate larger actuators. Feedback from motors is processed through IndraDyn/Hiperface/1 Vpp/TTL feedback interfaces, permitting mixed encoder formats on the same axis card. Integrated functional safety reaches Safe Motion (SIL2 / Cat. 3 PL d), so velocity-related hazards can be mitigated without external relays. A maximum command pulse width of 100 ms is accepted for time-critical drive enable signals, and the module’s front face measures only 49.5 mm wide, leaving adjacent slots free for communication or power modules.
