Product Description:

The CSH01.1C-PL-EN1-MEM-MD1-NN-S-NN-FW is a drive control section produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. It mounts in an IndraDrive rack and serves as the central logic element that connects higher-level PLCs to individual servo power stages. By interpreting motion commands and local I/O, the unit generates deterministic axis control signals that coordinate conveyors, pick-and-place robots, and process machinery in automated manufacturing lines.

This controller exchanges data with the drive bus over a parallel interface, giving fixed-width signal paths that minimize protocol latency. Its encoder signal processor reproduces feedback pulses at 1 MHz so external position counters can track motion without loss of resolution. For absolute position chains, it can output frames in absolute SSI format, allowing direct linkage to master controllers that expect serial absolute words. The encoder supply rail delivers 8 V to power external transducers, and the MD1 terminal block accepts control signals referenced to 24 V logic, offering twelve digital inputs for sensors, eight transistor outputs for status flags, and resolver excitation at 4 kHz for analog angle decoding.

Channel density is arranged in 4-input and 4-output groups, yielding a total field capacity of 16 In / 16 Out when every parallel bank is installed. Each output can source up to 0.5 A, which is enough to drive contactors or indicator lamps without auxiliary relays. Motion feedback lines are routed through a MEM extension that supports cable lengths of up to 40 m, while rotor angle conversion is stabilized by a resolver carrier of 18.2 Vpp delivered through the HSF interface. The module works with MKD, MKE, and MHD servo motors, and it leaves machine-level safety to external devices.
