Product Description:
The CSH01.SE-ENS-NNN-NNN-S2-S-NN-FW CDB Control Unit is an industrial motion control unit used to deliver precise, configurable control performance with reliable connectivity and fast cyclic times. This control unit is manufactured by Bosch Rexroth Indramat and is completely configurable to fulfill a wide variety of motion control needs.
The Sercos II interface of this control unit handles the communication, which in turn provides deterministic data transfer for synchronous high-speed automation processes involving drives and other connected components. This control unit also includes a standard encoder evaluation interface to provide the precise processing of feedback signals, which are paramount in closed-loop motion tasks requiring accuracy and repeatability. This control unit also integrates a standard operator panel for necessary control and status monitoring functions. The analog input section of this control unit is versatile as it includes two voltage inputs of ±10 V and two current inputs rated at 0–20 mA, for a broad range of analog transducers and process signals. For output functions, the CSH01.SE-ENS-NNN-NNN-S2-S-NN-FW control unit has two voltage analog outputs of a 0-10 V signal range for constant signal transmission to actuators or other devices.
This control unit is provided with a serial RS232 communications interface for system configuration and maintenance. This allows parameterization and diagnosis by directly accessing system settings and error tracing during commissioning or troubleshooting. This control unit is capable of high-speed control with current-control cycle times of 125 μs, velocity control of 250 μs, and position control of 500 μs to meet the demands for precision-controlled motion applications. For various drive configurations, this control unit supports a wide frequency range, including 2, 4, 8, 12, and 16 kHz. A normally open relay contact is also integrated in this control unit for easy control of external switching elements.
Frequently Asked Questions about CSH01.SE-ENS-NNN-NNN-S2-S-NN-FW:
Q: How does the 0–10 V analog output in CSH01.SE-ENS-NNN-NNN-S2-S-NN-FW enhance actuator response?
A: The 0–10 V output ensures clean, linear voltage control for actuators, enabling consistent performance across automation tasks that require smooth signal variation.
Q: Why is the ±10 V analog input range useful in industrial control?
A: It allows the unit to interface with a wide variety of sensors and transducers, supporting both low-voltage and full-range process signals.
Q: What is the purpose of the RS232 interface on the CSH01.SE-ENS-NNN-NNN-S2-S-NN-FW?
A: RS232 provides a simple, direct way to access diagnostic data and adjust system parameters without needing additional communication protocols or converters.
Q: How do switching frequencies up to 16 kHz benefit the control unit's performance?
A: Higher switching frequencies allow finer pulse control, reducing motor ripple and increasing the resolution of torque and speed regulation.
Q: Why is current control cycle time (125 µs) critical in high-speed motion systems?
A: It enables rapid current loop updates, essential for applications requiring tight torque control and dynamic load adjustments.
