Product Overview and Core Positioning

IndraDrive CSB01/CSH01/CDB01 is a modular servo drive control unit launched by Bosch Rexroth. As the control core of the IndraDrive drive system, it is divided into two series: BASIC (basic type) and ADVANCED (advanced type), suitable for single axis or dual axis drive scenarios. The product focuses on modular expansion, multi protocol compatibility, and high-precision control, which can be seamlessly matched with Rexroth IndraDyn series motors and various encoders. It is widely used in industrial automation equipment such as machine tools, packaging, printing, and material handling, meeting the driving and control needs of single machine or multi axis collaboration.

Installation and maintenance requirements

Installation specifications

Installation method: 35mm standard guide rail (EN 60715), vertically installed, with at least 2cm of reserved heat dissipation space above and below.

Wiring requirements: Digital I/O requires external 24V power supply. It is recommended to connect protective diodes in series to prevent polarity reversal; The signal cable and power cable are wired separately, and the shielding layer is grounded at both ends.

Insertion and removal restrictions: The control unit and power unit should not be inserted or removed more than 20 times to avoid poor contact.

Maintenance points

Firmware update: Update firmware through MMC card (PFM02.1) or Engineering interface, supporting parameter backup and recovery.

Fault diagnosis: Read fault codes through LED indicator lights, control panel or upper computer, and support 16 channel real-time data recording.

Spare parts requirements: Only Bosch Rexroth certified spare parts are allowed, and parameters need to be reconfigured after module replacement.

Typical Applications

Single machine drive: machine tool spindle/feed axis, packaging machinery actuator, printing machine tension control.

Multi axis collaboration: Material handling robots, assembly line multi axis synchronization, automated production line drive system.
