Description

The VT-HMC (Hydraulic Motion Controller) is a digital controller with integrated axis controller and programming functionality according to IEC 61131.

The following controller functionalities are available:

This enables, amongst others, the following operating modes:

Valve direct control

Command value presetting is done via the bus interfaces (XF20/XF21 or XF30), via the analog interface (XG20) or, alternatively, via an internal PLC program.

The feedback information of the actual value signals to the superior control system is provided optionally either via the bus interfaces (XF20/XF21 or XF30) or the analog/digital interface (XG20).

The controller parameters are set via one of the two Ethernet interfaces (XF20/XF21) (integrated switch functionality)

Monitoring

The digital control electronics enable comprehensive monitoring functions/error detection including:

IndraWorks MLD or DS PC program

To implement the project planning task and to parameterize the VT-HMC, the user may use the IndraWorks engineering tool (see accessories):

Slot for one SD memory card

The following data may be saved:

Only SD memory cards with SPI bus connection are supported (no SDHC memory cards).

The card must already be inserted when the device is switched on, otherwise it will not be detected. Cards that are not FAT-formatted are formatted automatically (FAT 32).

Automation experts agree:

In increasingly cross-linked production environments on the way to Industry 4.0, remote smart axes will be the solution of the future. Provided that they are able to communicate with superior systems via open interfaces. Rexroth fulfills this crucial requirement with the new HMC Hydraulic Motion Control.

Thanks to Multi-Ethernet and multi encoder interfaces and programming according to IEC 61131-3, the 1-axis controller for hydraulic drives fits into various designs in a future-proof manner.

Open interfaces and a shifting of the hydraulic functionality into the software are the decisive preconditions for remote intelligence. The drive-based HMC Motion Logic System by Rexroth fulfills these requirements with open interfaces and the best-in-class hydraulic encoder.

Best-in-class hydraulic controllers:

Rexroth has gathered unique knowledge of the interaction of hydraulics and Motion Control technology. Based on this knowledge, the control strategies for hydraulic and hybrid drives have been optimized and are represented in immediately usable software.
