Product Description:
The CSH01.1C-S3-NNN-MA1-MD2-NN-S-NN-FW is a single-axis controller module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It installs into IndraDrive systems where it processes motion commands, manages feedback devices, and exchanges real-time data with higher-level PLCs. Through this role, it synchronizes servo axes, actuators, and I/O points used in automated assembly lines, material-handling frames, and packaging equipment. This arrangement lets the control section handle interpolation, status monitoring, and command distribution within a compact drive-based architecture.
This module communicates with drives over Sercos III, and the deterministic ring supports a current control update every 125 µs. Its MA1 analog front end accepts differential command voltages in the range of ±10 V, digitized with 12-bit resolution for each of the 2 analog input channels. The analog outputs provide the same voltage span and resolution, so the controller can retransmit processed setpoints to external devices. On the MD2 extension, it provides 16 digital inputs for fast state capture, while the digital output bank is used for sequence flags, valve actuation, or light-stack control. Because the analog and discrete interfaces are built into the module, external reference devices and machine interlocks can be tied into the motion system without a separate interface card.
Network synchronization can be tightened to a minimum Sercos telegram time of 1000 µs, allowing coordinated multi-axis profiles without oversampling the bus. When a potential-free signal is needed, the onboard relay contact carries up to 1 A at 30 V DC, suitable for enabling motor contactors or safety circuits. For absolute position feedback, the SSI interface sources 24 V at 0.2 A and supports cable runs to 40 m at 1 MHz, giving flexibility in mounting encoders on distributed mechanics while keeping signal integrity within the drive cabinet environment. That combination supports remote encoder placement and simple interfacing to auxiliary devices that require isolated switching.
