Product Description:
The CSH01.1C-PB-EN2-NNN-MA1-NN-S-NN-FW is a plug-in control section from Bosch Rexroth Indramat. It belongs to the CSH Advanced Controllers series and installs on an IndraDrive power module. In operation, it closes the current, speed, and position loops that govern servo and induction motors, allowing production cells, material-handling stations, and packaging lines to execute coordinated motion sequences under deterministic control. This role is especially useful in applications where multiple drive functions must respond with consistent timing and repeatable motion behavior.
This section exchanges real-time commands over PROFIBUS, and its logic electronics are supplied with DC 24 V. Machine signals are handled through 7 digital inputs, 1 analog input, and 2 analog outputs, while an additional relay output supports contact-level switching. This mix of interfaces supports sensor monitoring, reference handling, and direct signal exchange with surrounding machine hardware. Position feedback reaches the unit through an encoder interface that supports EnDat 2.1, 1 Vpp, and 5 V TTL signals, and an RS-232 serial port is available for service access. The controller can also accept an Analog I/O Extension in its third expansion slot. Functional safety must be provided by external equipment, and output modulation is available at PWM frequencies of 4, 8, 12, or 16 kHz to balance acoustic noise and switching losses.
Internal processing is paced by a 62.5 µs current control cycle, a 125 µs speed control cycle, and a 250 µs position control cycle, giving the drive fast loop updates for smooth torque regulation and stable velocity tracking. Even at these rates, the board's electrical demand stays within a 26 W maximum power consumption envelope, which helps limit added heat inside the cabinet. These short cycle times support responsive behavior during acceleration, deceleration, and changing load conditions. The modest power draw also reduces the thermal burden on the control section while preserving fast processing for closed-loop motor control.
