Product Description:

The CSH01.1C-PB-ENS-EN1-EN2-S2-S-NN-FW is a control section from Bosch Rexroth Indramat's CSH Advanced Controllers series. It is fitted to IndraDrive systems to supervise axis position, execute real-time interpolation, and manage integrated safety. By interfacing with servo feedback devices and field networks, the card supplies deterministic motion commands to the power module, allowing precise spindle, gantry, or handling drives to be synchronized in automated production cells. It also coordinates feedback processing with the connected drive electronics during closed-loop motion control.

At the hardware level, the board consumes only 7.5 W, leaving the power stage to handle motor current while minimizing cabinet heat. Field communication is handled through PROFIBUS-DP and can be clocked up to 12 MBaud, so axis data travels quickly to PLCs. Each digital output channel can source 500 mA, sufficient for contactors or indicator lamps, while the 5 V encoder rail offers 350 mA for sensors that require low-voltage power. Three feedback sockets accept IndraDyn or HIPERFACE sine-cosine signals, EnDat 2.1 in differential TTL, or resolver inputs, enabling mixed encoder topologies on one motion axis.

The secondary encoder supply provides 5.0 V regulation for TTL tracks. An additional tap delivers 11.6 V so high-resolution encoders retain signal integrity over long cables. Resolver support uses an excitation of 18.2 Vpp at 4 kHz, allowing precise angle calculation even in electrically noisy machines. For diagnostics, the RS-232 port reaches 115 kBaud across cables up to 15 m, giving direct access without disturbing fieldbus traffic. Safe Motion technology is embedded, providing certified stopping and speed-monitoring functions that do not rely on external relays. Separate encoder and actuator circuits help keep feedback handling independent from output switching.
