Product Description:

The CSH01.3C-PB-NNN-NNN-CCD-NN-S-NN-FW is a control section from Bosch Rexroth Indramat's CSH Advanced Controllers series. Installed in an IndraDrive drive, it provides local processing, analog scaling, and fieldbus interfaces that coordinate servo axes, sensors, and supervisory PLCs. Within an automation cell, the module converts motion commands into drive-level signals and relays machine status back to higher-level control for packaging, printing, and material-handling equipment. Because it is the control section rather than the power stage, it manages communication and signal handling inside the drive.

An analog input impedance of 160 kΩ minimizes loading on external transducers, while the two analog outputs deliver up to 1 mA or a reference of 5 V for speed or torque setpoints. The logic section draws 8.5 W during steady operation, and a startup inrush of 4 A should be considered when selecting circuit protection. The controller has 11 digital inputs that accept 24 V signals for limit switches, home positions, or user buttons. Each input can capture pulses as short as 100 ms, allowing the controller to register brief event flags. Separate from the base electronics, the CCD option card adds 1 W of dissipation for encoder evaluation, so cabinet ventilation must account for the combined heat load.

The unit offers four digital outputs rated at 500 mA each to actuate contactors or indicator lamps, and they share the same maximum pulse width as the inputs. Network connectivity is handled through a D-Sub 9-pin female connector that links the PROFIBUS layer running on RS-485 and draws 2 W from the backplane supply. For diagnostics, an auxiliary RS-232 port supports point-to-point transfers up to 115 kBaud. This arrangement allows the control section to exchange cyclic network data while still providing a direct serial service connection.
