Product Description:
The CSH01.1C-SE-ENS-MA1-MD1-S2-S-NN-FW is a configurable control section released by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive modular drives, the unit processes encoder feedback, analog reference data, and fieldbus traffic so a servo axis can be commanded with deterministic timing. Its modular architecture combines separate function modules for sensor evaluation, motion arithmetic, digital I/O, and auxiliary power handling. The controller fits into centralized or distributed machine layouts where precise position, speed, and torque loops must run without an external PC.
In this configuration, the ENS option board manages high-speed position feedback. It supports a sine-signal bandwidth of 500 kHz and is powered from a regulated rail of 11.6 VDC while drawing 500 mA. To capture incremental edges from differential TTL encoders, the board accepts signals up to 400 kHz. The MA1 board supplies the analog process interface, and two input channels accept command values at 2 × ±10 V. These signals are digitized with a resolution of 12-bit. Matching output channels provide drive status signals on the same voltage range for downstream monitoring equipment.
The MD1 module covers discrete machine signals. It offers 12 × 24 V digital inputs for limit switches or interlocks, and eight 24 V outputs can each supply 0.5 A to actuators. A separate relay stage is rated at 24 VDC 1 A, and an auxiliary switched supply provides 24 VDC at 0.5 A for sensors. Serial diagnostics are available through an RS-232 port that reaches cable runs of 15 m and a peak data rate of 115 kBaud. Real-time motion synchronization with distributed drives is handled over a Sercos interface operating at 16 MBaud.
