Product Description:

The CSH01.1C-NN-ENS-MEM-MD2-NN-S-NN-FW is a control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Mounted in an IndraDrive amplifier, it supplies the processing power and I/O channels needed to coordinate servo axes, read encoders, and forward position or torque commands to the power section. The board is intended for multi-axis automation where a dedicated motion controller fits directly into the drive stack instead of using a separate PLC slot.

This controller accepts an analog command range of ±10 V with an input impedance of 160 kΩ, allowing precise velocity or torque references from external sources. It also provides a buffered analog output of 5 V at 1 mA for feedback to supervisory devices. The integrated MD2 module provides 16 digital inputs and the same number of outputs, and the outputs are routed through a D-Sub HD 44-pin connector for detachable cabling. Where interlocking or alarm circuits are required, a relay channel rated at DC 24 V, 1 A is available. The unit has no master communication interface, so network tasks must be handled by the host drive or a higher-level controller, while additional field sensors can be connected through the MD2 SSI interface on an RJ12 6-pin port.

The MEM channel can reproduce encoder signals with a sourcing capacity of 20 mA and a square-wave frequency limit of 1 MHz, which supports high-resolution position loops. Option slots include an IndraDyn, HIPERFACE, and 1 Vpp feedback interface, along with an encoder emulator and a digital I/O plus SSI evaluation card for broader motor and sensor compatibility. Cabinet layout is aided by the unit's 49.5 mm width, together with a 103 mm depth and a front-to-rear height of 241 mm. Those dimensions leave room for airflow and cable bend radius inside standard 300 mm deep control enclosures.
