Product Description:
The CSH01.1C-PB-EN2-MEM-MA1-S2-S-NN-FW is a drive controller component produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside IndraDrive power sections, this control unit processes fieldbus commands, feedback signals, and onboard I/O to regulate servo or spindle axes in automated machinery. By integrating communication, safety, and encoder handling on a single plug-in board, the module coordinates motion sequences and diagnostic data exchange between the plant-level PLC and each axis. This control unit acts as the central command layer within compact drive stacks used in packaging, printing, and material-handling equipment.
Its logic stage is supplied with a control voltage of 24 V DC, and at startup it can draw an inrush current of 4 A for a period limited to 100 ms. Continuous demand is just 7.5 W, which helps limit heat generation inside the cabinet during normal operation. The book-size housing is 241 mm tall, 103 mm wide, and 49.5 mm deep, so multiple units can mount side by side in multi-axis assemblies. Master communication uses PROFIBUS, and an RS232 port remains available for service tools. Encoder Interface 1 accepts EnDat 2.1, 1 Vpp, or TTL feedback, allowing the controller to work with several common motor feedback formats. Slot 2 holds an Encoder Emulation board, and slot 3 supports an Analog I/O Extension.
For analog tasks, the controller offers a differential input spanning ±10 V, allowing the drive to follow external speed or torque references. Its feedback channel supplies 1 mA at a reference of 5 V, so supervisory devices can read real-time values without loading the circuit. High-resolution position data reaches the logic through the EnDat 2.1 link. The emulation card can mirror that information for equipment that expects incremental pulses. This arrangement supports the use of external analog commands and digital encoder feedback within the same control stage.
