14/36 Digital axis control VT-HMC...1X | About this product
Bosch Rexroth AG, Edition 01.2021, RE 30239-B
The digital control electronics features comprehensive monitoring functions, fault
detection and more.
• Undervoltage
• Communication errors
• Cable break for analog sensor inputs and digital position measuring system
• Short-circuit monitoring for analog/digital outputs
• Monitoring of the microcontroller (watchdog)
• Temperature of electronics
• Overcurrent of 24 V sensor voltages and digital outputs
The measuring system of the hydraulic axes is incremental or absolute (SSI),
analog ±10 V and 4 to 20 mA.
The VT-HMC...1X is provided with a slot for an SD memory card. It can be used for
saving the PLC program and other optional data. Only SD memory cards with SPI
bus interface up to max. 4 GB are supported. When the control is switched on, the
card must be plugged, otherwise it is not recognized. Not-FAT-formatted cards are
automatically formatted (FAT32).
For process interfacing, the digital axis control VT-HMC...1X is equipped with
analog and digital inputs/outputs and with various bus systems. For more complex
machines it is useful to employ a higher-level control that, in conjunction with the
VT-HMC...1X, holistically controls the motion sequence of the machine and
monitors it in view of safety.
Main fields of application of the VT-HMC...1X are machine tools, plastics machines,
special machines, presses, and transfer systems.
The technology functions comprise:
• Sequence programming
• Positioning
• Pressure/force control
• Differential pressure control
• Position synchronization master/slave, average, min/max (optional)
• Force synchronization (optional)
The basis for function of the VT-HMC...1X is the creation of application-specific
parameter sets and, if required, user programs. These data are generated on the
PC and sent via TCP/IP to the VT-HMC...1X. The combination of user program and
parameter sets is called project.
The technical data, operating conditions and operating limits of the axis control
VT-HMC...1X can be found in the data sheet.
