Product Description:
The CSH01.1C-NN-ENS-NNN-MA1-L1-S-NN-FW is a motion and logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Designed for IndraDrive modular systems, it executes PLC sequences, interpolates axes, and relays commands between higher-level networks and drive inverters. In industrial automation cells such as pick-and-place gantries or web-handling lines, the device coordinates servo position loops, processes local I/O, and enforces safety interlocks to maintain cycle timing and machine integrity. It combines motion coordination with local control tasks, so one unit can manage axis commands, interlocks, and machine responses during repetitive machine cycles and fault handling.
On the analog extension board, the controller accepts 2 differential voltage inputs, and the differential topology improves common-mode noise rejection for sensors mounted far from the cabinet. Each channel accommodates a bipolar span of ±10 V, allowing direct connection of strain gauges, pressure transmitters, or motion potentiometers. With an input impedance of 1000 kΩ, the circuit draws negligible current so signal amplitudes remain stable. Conversion is performed at 12-bit granularity, providing 4096 digital steps across the full scale for fine process feedback. This arrangement supports accurate sensor acquisition when low signal loading and noise rejection are important. Two corresponding voltage outputs can deliver up to 10 mA, letting the controller drive external indicators or send setpoints to auxiliary amplifiers while preserving linearity over the same operating range.
Feedback devices interface through a shielded 15-pin female D-Sub connector that also feeds 12 V excitation to the encoder. An RS-232 service port supports data exchange up to 115 kBaud across cables not exceeding 15 m, which is useful for setup, diagnostics, and local parameter access. The connector layout supports orderly separation of feedback and service wiring within the control cabinet. Safety circuitry is included: a starting-lockout relay rated 24 V / 1 A cuts power, while a separate 3 mA acknowledgment line confirms circuit status. When activated, the drive executes a Category 0 stop, meaning torque is removed without controlled braking.
