Product Description:
The CSH01.1C-SE-EN2-EN2-MA1-NN-S-NN-FW is a single-axis control section from Bosch Rexroth Indramat's CSH Advanced Controllers series. Installed in an IndraDrive modular stack, it handles axis regulation, encoder evaluation, and fieldbus exchange so that a servo power unit can follow precise motion commands. Within an automation line, the module converts higher-level program instructions into synchronized position, velocity, and torque setpoints for the connected motor.
This control section communicates over SERCOS II, a deterministic optical bus that maintains microsecond-level timing between drives. Its logic terminals are powered by an auxiliary range of DC 19 to 30 V, allowing direct connection of sensors and fast switching outputs. Two plug-in EN2 boards furnish feedback channels that accept EnDat 2.1 / 1 Vpp / 5 V TTL signals, and the hardware exposes 2 × EN2 interfaces so dual encoders can be processed simultaneously. The MA1 option card provides differential analog inputs scaled to ±10 V, letting external process values influence the drive without separate converters. These inputs present an impedance of 1000 kΩ, which prevents measurable loading of the upstream measurement chain.
The MA1 inputs are digitized with 12-bit resolution, matching the depth used on its two ±10 V analog outputs to keep command and feedback scaling consistent. Separate onboard outputs deliver 0 to 5 V with a step size of 19.5 mV/Inc, useful for low-level references such as speed demand or trim signals. Form-C relay contacts rated at DC 24 V, 1 A can assert hardware enables or fault lines, while an 8-pole Mini-DIN connector supports RS-232 diagnostics from 9.6 to 115 kBaud. When cyclic data throughput is critical, the SERCOS channel can be driven up to 16 MBaud, sustaining tight jitter limits even in large drive rings.
