Product Description:

The CSH01.1C-SE-ENS-EN2-MD1-NN-S-NN-FW controller is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. As a compact drive logic module, it coordinates position, velocity, and diagnostic exchange between a central PLC and servo inverters on automated packaging, material-handling, and assembly equipment. It mounts in the first slot of an IndraDrive power section and provides the processing, bus links, and status relays needed to keep decentralized axes synchronized under hard real-time conditions. This arrangement allows the control section and power section to operate as a closely integrated drive platform.

At the core of the unit, base electronics draw 7.5 W in idle mode, allowing low heat dissipation inside sealed cabinets. Command and parameter traffic to the drives travels over SERCOS II, giving deterministic telegram timing for coordinated motion. An extension socket accepts 12 additional digital inputs, while another header supports 8 configurable digital outputs. Each output channel can switch loads up to 24 V / 0.5 A. These I/O points allow sensors, limit switches, and small actuators to connect directly without extra interface boards. The module also contains galvanically isolated signal grounds to reduce noise coupling into encoder circuits and the fieldbus.

Two independent encoder ports are available. The first supports Standard Encoder Evaluation, while the second accepts EnDat 2.1, 1 Vpp, or 5 V TTL signals. The En2 supply delivers 5.0 V at 350 mA and stays regulated when the connected sensor presents a 35 Ω load, while the separate Ens rail provides 11.6 V at 500 mA for absolute encoders that require a higher bias voltage. During power-up, the controller tolerates an inrush of 4 A lasting up to 100 ms. Control telegrams circulate through the optical ring at 16 MBaud, and machine status can be forwarded through a Ready relay rated at 24 V DC / 1 A. This relay gives the higher-level control a simple way to monitor basic drive readiness.
