Product Description:

The CSH01.1C-C0-ENS-EN2-NNN-NN-S-XP-FW is a single-axis control section produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Mounted on the front of an IndraDrive power unit, the board hosts firmware that executes position, velocity, and torque loops for one drive channel. Acting as the bridge between machine-level PLC instructions and the high-current inverter stage, it supplies the regulated command and feedback pathways that keep industrial robots, packaging lines, and material-handling axes on target.

The analog interface accepts command voltages against an input impedance of 160 kΩ, minimizing loading on upstream signal generators. For outbound references, the card sources up to 1 mA with a step size of 19.5 mV/inc over a full-scale range that tops at 5 V. Each discrete output channel can switch loads up to 500 mA, while telegrams and diagnostics travel over the dual-protocol bus of CANopen / DeviceNet. These values show how the controller exchanges finely resolved analog commands, switches valves or contactors directly, and synchronizes operation with neighboring motion axes on a common network.

A group current ceiling of 1000 mA applies when several digital outputs are energized simultaneously, and the on-board relay contact can carry up to 1 A for safety-rated feedback circuits. The dedicated EN2 encoder port furnishes a regulated supply of 5.0 V at 350 mA and tolerates a total line resistance of 35 Ω, ensuring clean differential signals from incremental feedback devices. For SinCos or EnDat sensors on the ENS port, the board delivers 11.6 V with 500 mA, buffered by a 120 Ω input path that resists noise coupling. Logic electronics draw just 1 W from the auxiliary Co module, keeping thermal dissipation low inside tightly packed drive enclosures.
