Product Description:

Bosch Rexroth Indramat's CSH01.1C-PB-ENS-NNN-MEM-L2-S-XP-FW control section belongs to the CSH Advanced Controllers series. This plug-in card fits inside IndraDrive power units and acts as the motion processor that closes control loops, supervises bus communication, and conditions analog signals. It manages drive response, feedback evaluation, and setpoint handling within the power unit. In industrial automation cells, it provides the command path that lets servo axes, spindles, and I/O stations respond to a higher-level PLC with coordinated torque, speed, and position control.

The card's signal path is digitized by a 12-bit A/D converter, while two analog outputs source up to 1 mA each at a reference level of 5 V for drive-based setpoints. Core electronics consume 7.5 W under nominal load, and the current loop is recalculated every 125 µs for responsive control in dynamic applications. Additional power draw is divided among the ENS module at 6 W, the MEM option at 2 W, the PB interface at 2 W, and the front-mounted standard panel at 1 W. Encoder support includes 11.6 VDC excitation, 120 Ω differential input impedance, and acceptance of incremental feedback streams up to the TTL limit. This arrangement supports stable signal handling for both feedback devices and analog reference channels used by the drive.

Field communication is handled by a PROFIBUS DP port on a 9-pin D-Sub female connector, and serial diagnostics can be carried out through an RS-232 channel that reaches 115 kBaud. The controller can deliver up to 500 mA to various encoder types, which helps maintain reliable sensor power over long cable runs. Its analog input path maintains accuracy up to 500 kHz, and bidirectional TTL counters remain functional to 400 kHz for high-resolution encoder processing. These interfaces allow the control section to exchange network data and service information through the installed communication hardware. The modular division of internal loads helps keep supply rails stable during peak motion phases.
