Product Description:
The CSH01.3C-CO-NNN-MA1-CCD-L2-S-NN-FW is a control section from Bosch Rexroth Indramat and is part of the CSH Advanced Controllers series. Installed in modular servo drive racks, the unit serves as the central processor that coordinates axis motion, fieldbus traffic, and embedded safety for industrial automation equipment. By hosting option cards such as the MA1 analog expansion and dedicated communication modules, it provides the electrical interface between the power section of an IndraDrive cabinet and external supervisory PLCs.
On the network side, the controller is wired in a line bus topology with a terminator value of 124 Ω to minimize signal reflections. Fieldbus exchanges occur through CANopen/DeviceNet, giving the drive deterministic cyclic telegrams for velocity or torque commands while diagnostic telegrams share the same channel. Four combined digital I/Os are available as 4 software-configurable points, allowing fast interlocking without extra cards. For higher-level coordination, the CSH section assumes the Cross-Communication Master role, and its Ethernet interface complies with IEEE 802.3, enabling peer status exchange among drives in less than a millisecond.
In addition to the base board’s two onboard analog outputs, the MA1 plug-in provides two additional voltage-scaled analog outputs, two differential inputs, and a single onboard analog input; both conversion paths use 12-bit resolution for repeatable setpoint reproduction. Machine feedback points are supplemented by a form-C relay with 1 N/O contact capability for ready or fault indication. Serial communication is handled through an 8-Pin MiniDIN RS-232 socket that supports cable runs up to 15 m. For personnel protection, the drive can assert the integrated Safe Torque Off function, removing drive energy without dropping control power.
