Product Description:

The CDB01.1C-SE-EN1-NNN-MA1-NN-S-NN-FW is a modular control section manufactured by Bosch Rexroth Indramat for the CDB Control Units series. It plugs into a compatible power section to manage multi-axis drive assemblies, issuing motion commands and collecting feedback for coordinated motor operation in industrial automation cells such as packaging, printing, and material-handling stations. By separating the control section from the power hardware, the platform supports compact cabinet layouts and coordinated control of multiple motor functions from one drive assembly. This arrangement lets the control electronics handle feedback evaluation and command distribution while the matching power section delivers motor current.

This unit supervises two servo channels, and the dual-drive configuration is identified by an Axis Count 2 code. Internal electronics draw only 9 W at idle, which helps limit standby heat inside the cabinet. Command data exchange with the drive stack occurs over the deterministic SERCOS II interface, and telegrams are transmitted at speeds up to 16 MBaud so real-time setpoints and status data can be refreshed with very short latency. The EN1 plug-in card supports resolver or HSF feedback, energizes the sensor interface with 8 V, and modulates torque reference pulses toward MHD or MKD motors with an output carrier of 4 kHz. That combination is suitable for paired axes that must stay synchronized during indexing, transfer, or registration tasks.

Complementary analog processing resources refine those digital controls. The MA1 module provides two differential inputs and two voltage outputs, and signals are converted with 12-bit resolution for precise speed or torque scaling from auxiliary process instruments. Time-critical triggers can be generated with a maximum pulse width of 60 ms, and interlock devices may be driven through a form-C relay contact rated at DC 24 V, 1 A. Power-up demand on the cabinet supply is limited by a typical inrush current of 6 A, while ongoing diagnostics can be accessed through the RS232 service port. The analog and service interfaces allow the unit to exchange status and process values with surrounding machine controls without separate interface hardware. No integrated safety technology is included, so any required safety function must be handled by external equipment.
