Equipped with an integrated frequency converter and sensors, this hydraulic power unit is ready for Industry 4.0 applications, offering smart capabilities for modern industrial environments. It operates at a maximum pressure of 280 bar and includes a tank with the capacity to hold a significant volume of hydraulic fluid HLP. The cooling capacity is maximized to ensure optimal performance even under demanding conditions. The Bosch Rexroth CYTROPAC-1X/20 conforms to the CE Machinery Directive EC appendix B declaration of incorporation, signifying its compliance with European safety standards. With a max flow rate, oscillating volume specifications, and designed for a supply voltage of 400 V AC, this power unit maintains its performance reliably over time. Its weight is carefully calibrated to balance stability and ease of installation. This model's performance class is top-tier within its product group ID range, making it an excellent choice for applications requiring precise hydraulic control in confined spaces. The integrated cooling system not only cools the motor but can also be optionally used for active oil cooling. Additionally, features such as the integrated oil drain facility, reduced oil volume due to degassing-optimized tank design, and pre-start control underscore the CYTROPAC-1X/20's commitment to efficiency and user convenience.

1)	Prestart control: By means of a control signal, the drive unit is already accelerated before hydraulic actuators are connected. This reduces the collapse of pressure and you can possibly do without a hydraulic accumulator.
2)	Sleep function: By means of the integrated speed monitoring, the CytroPac is switched off in case of flows smaller than a set threshold value. This increases the energy efficiency and you can, for example, realize an accumulator charging circuit without additional control signals (see R911378635 Sytronix short instructions).

It has to be ensured before the commissioning that on the customer side, a pressure relief valve (set pressure 10% over nominal pressure, however at most 260 bar) has been installed in the pressure line. The feed-in and 24 V supply must be secured on the customer side, as described under “Electrical connection”. For the cooling of the motor and the frequency converter, the power unit must imperatively be connected to cooling water. The connection of the power unit to the machine must be realized by means of hydraulic hoses (no rigid pipeline admissible). It must be ensured on the customer side that the cooling water supply temperature does not fall below the dewpoint of the ambient air of the power unit. The maximum operating pressure of 240 bar must not be exceeded.

Read-in and read-out of the power unit parameters

The Rexroth EFC 5610 frequency converter is integrated into the CytroPac; this frequency converter can be connected to an external computer by means of a mini USB cable.

Access to and setting of the frequency converter is possible by means of the ConverterWorks software. The software can be downloaded at the website www.boschrexroth.de.

Changing the operating pressure:

Connect the power unit to the voltage supply. Open the ConverterWorks software on an external computer Connect the CytroPac to an external computer, using a mini USB cable and interface 14X1 The software will automatically establish a connection to the power unit (if not, click Tools → Connect/Switch online) The control pressure can be changed using parameter F1.05 in the parameter editor.

The operating instructions R912006684 contain further information on the handling of the frequency converter. You can also download this document at www.boschrexroth.de.
