Product Description:

The CSH01.1C-SE-ENS-MEM-MD1-S1-S-NN-FW is a single-axis control section from Bosch Rexroth Indramat, positioned within the CSH Advanced Controllers series. As a modular controller card, it plugs into an IndraDrive power section to coordinate motion axes, process field feedback, and supervise safety tasks in automated machinery. In production lines, printing presses, or packaging equipment, this part processes command data and encoder signals to maintain precise speed, torque, and position loops.

Its control channel exchanges real-time setpoint and status data over the SERCOS II optical ring, reducing cycle jitter for multi-axis synchronization. The card draws only 7.5 W at the backplane, so enclosure heat rise is limited. Position feedback enters through a 15-pin D-Sub female socket that carries IndraDyn, HIPERFACE, and 1 Vpp analog signals; absolute and incremental formats are accepted, and signals can be generated internally up to 1 MHz for downstream devices. When power is applied, the section experiences an inrush of 4 A lasting approximately 100 ms, after which current falls to the steady-state level. The integrated MD1 expansion board provides 12 digital inputs and 8 digital outputs at 24 V for quick PLC handshakes, while the Safety Technology I/O layer handles emergency-off channels that meet category requirements.

For diagnostics and drive setup, the board offers an RS-232 port that supports transfer rates up to 115 kBaud, allowing direct communication during local diagnostics and drive setup without fieldbus equipment. During safety-related operation, the auxiliary line may deliver up to 1.6 A, so cabinet power budgeting must account for this peak. The emulation circuitry maintains clean signal replicas at the declared frequency ceiling, which supports precise phase locking for follower drives.
