Product Description:

Bosch Rexroth Indramat manufactures the CSH01.1C-PL-EN1-MEM-MA1-L1-S-NN-FW as a plug-in control section within the CSH Advanced Controllers series. The module manages axis commands, feedback processing, and I/O coordination inside IndraDrive systems, allowing a drive to exchange position, velocity, and status data with the higher-level PLC. By housing communication, encoder evaluation, and power logic on one card, it forms the central decision layer that directs servo amplifiers used in assembly lines, packaging machines, and other motion-centric equipment.

The controller draws 7.5 W from the 24 V backplane, so the supply only needs a small reserve for logic functions. For the EN1 encoder interface, it provides a regulated 8 VDC / 250 mA source for Hall sensor feedback and a separate resolver excitation of 18.2 Vpp / 4 kHz / 70 mA, preventing crosstalk between measurement channels. Position data can be retransmitted through the integrated encoder emulation that outputs Incremental + SSI signals, letting external positioning modules read identical motion information without an additional transducer. A safety-rated acknowledgment contact on circuit L1 can switch loads up to 24 VDC / 1 A, giving the drive a direct path to confirm that emergency stop or guard-door circuits have been reset.

On the application side, the MA1 option adds 2 analog inputs and 2 analog outputs, with each input buffered by 1000 kΩ impedance and each output capable of driving 1 kΩ loads. The converter has 12-bit resolution, which supports fine torque or speed commands. High-speed control data travels over the MEM channel, whose maximum output frequency reaches 1 MHz, matching rapid command cycles required for multi-axis interpolation. Sixteen digital inputs and sixteen outputs arrive through a D-Sub 37 connector on the PL interface, and a starting lockout safety function disables drive activation until the supervisory controller authorizes motion.
