Product Description:

The CSB01.1C-SE-ENS-MEM-L1-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSB Drive Controllers series. Installed beside a compatible power module, it forms a complete servo drive that governs torque, speed, and position loops on automated machinery. The board handles motion commands from higher-level controllers, interprets encoder feedback, and delivers gate signals to the inverter for precise axis movement in packaging lines, pick-and-place stations, and material-handling cells. Its mechanical format occupies a single slot in the drive rack and connects through a multipole backplane.

The board is configured for a single-axis topology, and cyclic communication with the motion network is handled through SERCOS fiber optics. Its current controller refreshes every 125 µs, giving fine granularity for torque regulation. The integrated encoder supply delivers DC 11.6 V at up to 300 mA to power absolute feedback devices. Digital outputs on the I/O header can source 0.5 A per channel while maintaining 24 V logic, and the bus can draw a maximum of 1.1 A from the external supply. A standard encoder evaluation option occupies slot one, the second optional channel provides encoder-emulation pulses for legacy counters, and relay signaling is available through a single normally open contact.

During power-up, the module withstands an inrush of 4.5 A, and the control section limits each PWM command to a peak width of 110 ms to reduce stress on the switching devices. The integrated safety circuit uses starting lockout, so the drive cannot enable torque until all monitored contacts are closed. Service access is available through the RS-232 port without disrupting the real-time network. Internal supervision then passes validated position data to the power section, while galvanic isolation between the logic circuits and the DC bus helps reduce common-mode noise that could disturb adjacent axes.
