Product Description:

The CSH01.1C-PL-ENS-EN1-NNN-S1-S-NN-FW is a single-axis motion controller card manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in drive racks, this unit supervises one servo axis by processing position feedback from primary and secondary encoders and forwarding setpoint data through its parallel bus. Within an automation cell, it bridges the machine PLC, the drive inverter, and integrated safety circuits so that coordinated motion, rapid stops, and diagnostics occur within the required cycle times. This arrangement allows the controller to manage axis behavior centrally while keeping feedback evaluation and command exchange inside the drive system.

This controller’s base power draw is only 7.5 W, so cabinet heat rise is minimal during normal operation. During power-up, it can absorb an inrush of 4 A, which is useful when sizing the supporting power circuit. Logical signals move across a parallel interface that also provides 16 In / 16 Out discrete channels, letting the drive exchange real-time status bits without extra fieldbus hardware. Position data from rotary or linear motors is accepted through a primary encoder input that supports IndraDyn, HIPERFACE®, 1 Vpp formats, enabling high-resolution feedback across different motor and encoder combinations. For time-critical control tasks, the card can issue drive-enable or brake commands with a maximum pulse width of 100 ms, helping the axis react consistently to watchdog events or limit faults.

The integrated safety block connects through a D-Sub 9 female plug, and its input channel tolerates 24 V / 3 mA logic for external safety signaling. Its solid-state output can source up to 24 V / 0.5 A toward external contactors, supporting direct interaction with downstream safety devices. A redundant relay path rated at 24 VDC / 1 A is present for hardwired STO loops, while the safety section itself is powered from a 24 VDC rail with current available for the internal circuits. For service access, the front panel includes a RS232 port that supports direct parameter transfer from a laptop or terminal emulator. This makes local setup and diagnostics possible without adding another communication interface to the rack.
