Product Description:
The CSH01.1C-SE-EN1-NNN-NNN-L1-NN-FW controller option is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It installs on IndraDrive power modules and provides high-speed axis coordination, position processing, and local safety interlocks inside an automated cell. By combining motion control, fieldbus handling, and encoder evaluation on a single board, the unit streamlines cabinet layouts and reduces wiring complexity for multi-axis packaging, printing, or material-handling machinery.
Control power is drawn from a dedicated supply of 24 V DC, and the card limits initial charging to a typical inrush of 4 A so auxiliary supplies do not trip. Its analog input channels present an impedance of 160 kΩ, allowing precise sensor measurements without loading transducers, while each analog output updates in steps of 19.5 mV/inc for fine reference scaling to external drives or valves. Digital outputs can source or sink up to 500 mA, which is sufficient for direct control of indicator lamps and similar low-power devices. Motion commands and diagnostic data are exchanged over the SERCOS II fiber-optic ring, which supports deterministic cycle times for synchronized axes. For feedback, the EN1 interface accepts resolver or high-speed feedback signals and provides 8 V DC excitation, 18.2 Vpp carrier amplitude, and 4 kHz reference frequency for stable position tracking.
During continuous operation, the electronics dissipate only 7.5 W, which simplifies thermal management inside compact panels. A form-C relay on the board can switch control circuits up to 30 V DC / 1 A, giving the system a galvanically isolated signal for drive enable or fault annunciation. Time-critical strobes are permitted with a maximum pulse width of 100 ms, preventing unintended latching of actuators during short control events. The integrated safety function is Starting Lockout, which keeps power stages inhibited until the controller confirms correct startup conditions through internal checks and the fieldbus handshake.
