Product Description:

The CSH01.1C-PL-ENS-EN2-NNN-S1-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. This control section is intended for mounting on IndraDrive power units where it executes motion commands, acquires field data, and forwards feedback to higher-level PLCs. By combining analog, digital, encoder, and safety resources on a single plug-in module, the unit coordinates servo axes, synchronizes positions, and supervises machine safety circuits in general industrial automation.

The two analog input channels present an impedance of 160 kΩ, so connected transducers are not significantly loaded. Each sample is quantized at 1.23 mV/inc, allowing fine scaling of process variables. On the output side, the controller drives reference signals into loads down to 5 kΩ, and those signals change in steps of 19.5 mV/inc, supporting moderate-resolution speed or torque setpoints. Command data can also be exchanged over the parallel interface, while service diagnostics use the RS232 port that reaches a line rate of 115 kBaud and works over cable runs up to 15 m. Together with 12 V primary and 5 V secondary encoder supplies, as well as support for EnDat 2.1, 1 Vpp, and 5 V TTL feedback formats, the controller can interface with a wide range of motors and measuring systems.

Discrete control tasks are handled through 16 parallel digital inputs and 16 parallel digital outputs, which let the drive react directly to machine sensors or actuate relays without extra hardware. Safety Technology I/O augments these lines with a dedicated input rated at 24 V / 3 mA, an auxiliary output of 24 V / 0.5 A, and a relay contact specified for DC 24 V / 1 A. These channels permit emergency-stop loops, guard door monitoring, and safe torque off functions to be wired locally so that the encoder-based motion supervision remains active even when the higher-level control is absent.
