Product Description:

The CSH01.1C-PL-ENS-NNN-NNN-L1-S-NN-FW control section comes from Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It is a modular drive controller card that inserts into IndraDrive power units, where it handles signal conditioning, motion calculation, and field I/O for multi-axis automation. By linking higher-level PLC commands with the power stage, the board directs speed, torque, and position loops for electric servo motors used on packaging lines, material handling systems, and machining centers.

Its analog measurement channel offers an input impedance of 160 kΩ, which helps prevent signal sag from delicate sensors. The A/D converter distinguishes increments as small as 1.23 mV/inc. Outbound reference voltages leave the card with a D/A granularity of 19.5 mV/inc and can drive loads down to 5 kΩ without distortion. Each sourcing digital output can deliver up to 500 mA, providing enough current for solenoid pilot valves or indicator lamps. Base electronics dissipate 7.5 W, while the installed PL, ENS, and L1 options add extra power draw that must be included in the DC-bus load calculation. A parallel interface supplies deterministic handshake lines, and the onboard encoder evaluator provides a stabilized 11.6 V supply for feedback devices.

For discrete machine control, the board exposes 16 In / 16 Out points, and the relay channel carries switching loads up to 30 VDC / 1 A for galvanically isolated tasks. Diagnostic links run over an RS-232 connection of up to 15 m through the keyed 8-pin Mini-DIN connector, allowing access from a laptop outside the enclosure. The integrated safety circuit provides a Starting Lockout, which blocks drive-enable signals until an external logic path confirms safe conditions. The diagnostic port and safety circuit are kept separate from the discrete I/O paths, which helps keep control and status functions organized inside the drive assembly.
