Product Description:
The CSH01.1C-NN-ENS-MEM-MA1-L1-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive rack, it executes current, velocity, and position loops for a single servo axis. In assembly, packaging, and machining cells, this plug-in board keeps motors aligned with PLC sequences and tooling events. Its architecture supports mixed analog, digital, and encoder feedback channels so one card can service diverse drive tasks.
Critical control tasks run in tightly timed loops. The current regulator refreshes every 125 µs, velocity calculations run every 250 µs, and position error is corrected every 500 µs; these intervals minimize lag between commanded and actual motion. Command voltages enter through a differential input rated at ±10 V and 160 kΩ, while diagnostic or following-error signals can be returned through a 5 V, 1 mA analog output. The MA1 expansion supplies two analog inputs and two analog outputs with 12-bit resolution for auxiliary sensors. A TTL counter accepts pulse trains up to 400 kHz, giving the drive direct access to high-speed reference encoders. The encoder connector can source 500 mA, so feedback devices do not require external power. Master communication hardware is not installed, allowing the card to operate locally or under a separate fieldbus master.
The emulation circuit can stream a simulated encoder signal at 1 MHz, and it maintains clean edges over a 40 m cable so remote monitoring equipment receives accurate phase information. For mixed-protocol installations, the all-in-one IndraDyn/Hiperface/1 Vpp/TTL interface reduces the need for additional converter boards. A dry contact rated at 24 V / 1 A is available for ready, fault, or brake commands. Functional safety is addressed by a starting lockout that conforms to Stop Category 0, removing power instantly while permitting a controlled restart after clearance. The standard front-mounted control panel keeps local parameter access, and the unit’s resources permit standalone axis tuning or subordinate operation under a multi-axis master.
