Product Description:

The CSH01.3C-PB-ENS-ENS-CCD-L2-S-NN-FW is a modular control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It installs on IndraDrive power units and performs real-time regulation of current, speed, and position loops, acting as the motion core in automated packaging, handling, and assembly systems. By translating high-level PLC commands into deterministic drive signals, the board coordinates multiple servo axes and manages diagnostic data within the overall control architecture of an industrial cell. This arrangement lets the control section handle motion tasks directly at the drive, which supports consistent axis response during synchronized machine movement.

At the drive interface level, the unit closes its current loop every 62.5 µs, allowing tight torque regulation during rapid load changes. Field data reach the section through a PROFIBUS-DP port, so communication remains orderly when several axes share one bus. Up to 11 digital inputs can be mapped for limit switches or homing sensors, while 4 digital outputs provide drive-ready or fault signals to external controllers. The PWM stage can be commanded at a switching frequency of 16 kHz, reducing audible noise and improving current resolution during high-speed motion. These onboard interfaces allow the controller to exchange status signals quickly without requiring separate I/O hardware for basic axis functions.

Parameterization and diagnostics can also be performed over the engineering link that runs at 100Base-TX, giving Ethernet bandwidth for data transfer and oscilloscope traces. The ENS encoder interface delivers 500 mA at 11.6 V, supporting absolute multi-turn encoders without external supplies. A hardware-based safety circuit provides Safe Torque Off, which removes power to the output stage in safety-related stops. For legacy terminals, the RS232 service port supports rates up to 115 kBaud across a 15 m cable. The board also offers one analog input, two analog outputs, and two probe inputs, and it operates in cross-communication master mode so peer drives can be synchronized without direct PLC intervention.
