Product Description:

The CSH01.3C-PL-ENS-ENS-CCD-S2-S-NN-FW is a motion-control option card manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted inside an IndraDrive stack, it coordinates axis positioning and manages real-time I/O so automated machinery can execute deterministic motion profiles without relying on an external PLC. It is intended for applications that need closed-loop motion control and fast signal exchange between the drive and connected machine devices.

To accommodate mixed-signal requirements, the board provides 2 analog output channels for reference voltages and 16 parallel digital inputs that accept 24 V status bits. A matching bank of 16 parallel digital outputs propagates actuator commands and fault flags, and main communication with the power section uses a parallel interface that transfers command words in microseconds. During operation, the controller draws a steady 8.5 W from the backplane, while the PL processor group is allowed a peak of 1.2 A so timing logic remains deterministic under high interrupt traffic. The built-in safety layer is classified as Safe Motion, enabling drive-integrated monitoring of velocity, position, and stopping without extra relays. An Ethernet port supporting 100Base-TX also permits standard network access.

The dual ENS encoder slots supply feedback power at 11.6 V DC and up to 500 mA, letting two high-resolution encoders operate simultaneously. Signal edges on these TTL inputs can be evaluated at 400 kHz, matching fast linear scales or high-pole servomotors. For cross-controller diagnostics, the unit assumes a master role on the internal bus, while a dedicated RS-232 maintenance port supports transfer speeds up to 115 kBaud over cables as long as 15 m. These interfaces support synchronized axis operation and provide access for serial diagnostics without requiring additional interface cards.
