Product Description:

The CSH01.1C-PB-EN1-NNN-NNN-L1-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The module plugs into drive racks and operates as the command processor that links PLC instructions to motor feedback. By combining fieldbus communication, analog acquisition, and digital switching in one slot, it manages speed loops, torque commands, and diagnostic messaging that keep conveyors, packaging stations, or handling robots synchronized with the plant sequence. This integrated layout reduces the need for separate interface cards and keeps signal processing close to the drive hardware. That arrangement lets the control section handle local signals and networked commands within the same module, which helps simplify cabinet layout.

Communication with higher-level PLCs travels over the integrated PROFIBUS-DP channel, and telegrams are exchanged at up to 12 MBaud, allowing short cycle times for setpoint updates. Sensor data can enter through an analog input with a resistance of 160 kΩ, which minimizes loading on remote transducers. Actuator signals are provided by an analog output rated at 5 V / 1 mA, allowing direct speed references to downstream drive stages. For discrete devices such as relays or brake valves, the board supplies digital outputs that can source 0.5 A. All bus wiring terminates on a D-Sub 9-pin female connector for straightforward cable connection and service access.

The feedback side supports resolver transducers; excitation is delivered as 18.2 Vpp AC at 4 kHz, and the controller reads the returning sine-cosine pair through a hybrid Resolver/HSF interface to close the position loop. Functional safety is addressed by integrated starting-inhibit logic. The hardware enforces a Starting Lockout condition until the external enable line is in a safe state, while emergency-stop behavior conforms to Category 0 and removes power without a controlled ramp. Resolver operation supports continuous position tracking while the control section supervises safe start conditions before the axis is enabled.
