Product Description:

The CSH01.1C-NN-ENS-NNN-MD1-S2-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on an IndraDrive power unit, the board executes position, velocity, and torque loops while coordinating Safe Motion functions that protect personnel and machinery in automated lines. By combining analog command handling, encoder evaluation, digital I/O, and integrated safety relays, it becomes the central logic element that links drives, sensors, and higher-level PLCs inside an industrial automation cell.

The analog front end processes reference signals up to 1.4 kHz, allowing rapid setpoint changes without noticeable phase lag. A high input impedance of 160 kΩ minimizes loading on external signal sources, so precision potentiometers or DAC cards are not driven beyond their linear region. The module can source up to 1 mA on each analog output channel and delivers a fixed output swing of 5 V, giving the host drive a repeatable command range for torque biasing or feed-forward terms. Position feedback enters through a shielded 15-pin female D-Sub connector that routes encoder signals to the onboard standard encoder evaluation circuit. This path keeps measured shaft angle synchronized with the internal motion processor.

The encoder supply rail provides 12 V to incremental or absolute sensors, eliminating the need for an external power tap. Machine control signals reach the MD1 port, where 12 opto-isolated digital inputs and 8 transistor outputs handle start commands, limit switches, and drive-ready indicators. Each output can sink 0.5 A for contactor coils or indicator lamps, while a ready relay rated at DC 24 V / 1 A interfaces with system e-stops. A second relay within the Safe Motion block mirrors that rating for category-appropriate safety chains. Configuration and diagnostics are available through the RS232 serial interface, enabling parameter backups and real-time trace capture without removing the unit from the cabinet.
