Product Description:
The CSH01.1C-CO-ENS-EN2-MEM-L1-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It is installed in IndraDrive assemblies to process encoder feedback, manage drive functions, and exchange motion commands with higher-level PLCs in automated machinery. This role allows the unit to interpret feedback signals and coordinate responses between the motor, the power section, and the machine controller during normal operation. By combining encoder evaluation, fieldbus communication, and integrated safety functions, the unit coordinates axis positioning and ensures that power stages energize motors only when permitted operating states are present.
The controller communicates with host systems through CANopen / DeviceNet, allowing deterministic data exchange over a single twisted-pair network. This network connection supports integration in distributed automation systems where command exchange and device status must remain consistent across the drive system. For encoder simulation, it supports an emulation cable length of 40 m, and the simulated signals remain accurate over that distance because the output stage is galvanically isolated from internal logic. Primary encoder ports can source up to 500 mA at a stabilized 12 VDC, so resolvers or absolute encoders receive enough power without external supplies. A standard single-line control panel on the front plate displays status codes and supports local operation while the fieldbus remains connected.
The TTL monitor accepts feedback edges up to 400 kHz, enabling precise speed calculation on high-resolution measuring systems. When secondary transducers are wired, the permissible cable length reaches 75 m, and the differential driver maintains signal integrity into a load of 35 Ohm. A Stop function conforms to Category 0, removing drive energy immediately after a fault or manual stop request, and the starting lockout feature keeps the power stage disabled until a safe restart path is confirmed. Screw terminals on connector X60 are tightened to 0.5 Nm so that field wiring remains secure during vibration. This arrangement supports stable signal handling and reliable control behavior in automated drive applications.
