Product Description:
The CSB01.1C-PL-ENS-ENS-L1-S-NN-FW is a control section for Bosch Rexroth Indramat's CSB Drive Controllers series. It serves as the logic and interface layer between the main power section and surrounding automation hardware, receiving encoder signals, monitoring safety inputs, and forwarding processed data to higher-level PLCs. This arrangement keeps control functions separate from the power electronics in multi-axis systems. By combining field and service connections in a compact housing, the unit simplifies cabinet layouts and setup in motion control installations.
The housing has a width of 49.5 mm, a depth of 103 mm, and a height of 241 mm, allowing high-density stacking on DIN rails. Position feedback is accepted through TTL channels that tolerate frequencies up to 400 kHz, and an input resistance of 120 Ω limits loading on delicate encoder drivers. Serial diagnostics run through service routines at a maximum rate of 115 kBaud, enabling rapid parameter transfers without external adapters. Two 15-pin female D-Sub sockets provide separate encoder ports, and each port is powered by an internal regulated supply to help prevent undervoltage at the connected sensor.
An isolated supply delivers 500 mA at the encoder header from a stabilized rail of 11.6 V DC, so incremental or absolute encoders remain powered during fast axis moves. Parallel machine signals enter a 37-pin connector that carries 16 opto-isolated inputs and an equal number of transistor outputs for latch, limit, or tool-change commands. To drive contactors or indicator lamps, an onboard relay switches up to 30 V, 1000 mA. Start-inhibit compliance is achieved through a Stop Category 0 circuit routed to a 9-pin D-Sub, preventing unintended motion after emergency-off events. Additional maintenance access is provided by an RS-232 8-pin Mini-DIN service port.
