Product Short Description
Product Name: Bosch Rexroth CSH01 — IndraDrive Advanced Single-Axis Drive Controller Control Section
Product Introduction: The CSH01 is the ADVANCED series single-axis configurable control section of Bosch Rexroth’s IndraDrive modular servo drive system. It serves as the control core of the IndraDrive drive system, providing high-precision motion control with multiple expansion slots, multi-protocol compatibility, and cross-communication (CCD) capability. The CSH01 is designed to seamlessly match Rexroth IndraDyn series motors and various encoder types.

Application Scenarios: Single-axis high-precision servo control, machine tools, printing machinery, packaging machinery, robotics — anywhere advanced motion control with multi-protocol communication and functional safety is required.
Installation Requirements:
- Install as the control section paired with a compatible IndraDrive power section
- Connect 24 VDC power supply (max consumption 7.5 W; inrush 4 A / 100 ms)
- Seat optional expansion modules (encoder, communication, I/O, safety) into available slots per configuration
- Wire the primary encoder interface (IndraDyn/Hiperface/1 Vpp/TTL) to the motor
- Connect fieldbus communication via the appropriate D-sub or Ethernet interface
- Use RS232 (X2) or Engineering Ethernet (X26) for commissioning with Rexroth IndraWorks/debugging tools
Usage Precautions: The CSH01 is the ADVANCED variant — confirm this matches application requirements (vs BASIC CSB01 or dual-axis CDB01). Switching frequency is adjustable 2–16 kHz; select appropriate value for motor and application to avoid overheating. Inrush current is 4 A for 100 ms at 24 VDC — ensure power supply can accommodate. Safety functions L1/L2/S1/S2 must be configured per EN60204-1, SIL3/PL e, or SIL2/PL d requirements. Use the correct expansion modules (ENS/EN1/EN2) matching the encoder voltage requirement (12 V/8 V/5 V). Overvoltage and over-temperature protection are built-in; ensure proper cabinet cooling for the 7.5 W consumption plus power section heat dissipation.
