EtherCAT Interface

EtherCAT Interface
The hydraulic power pack is directly connected to the testControl machine electronics. This offers several advantages during the specimen insertion process and the test. The power pack is linked to testControl II via the EtherCAT interface, which is compatible with future generations, leaving the interface modules of the machine electronics available.

Ergonomic control

Ergonomic Control
All power pack functions can be controlled conveniently and ergonomically via the ZwickRoell testXpert III testing software or the machine remote control. This offers numerous advantages during the gripping process and the test.

Safety

Safety
Operator safety is guaranteed at all times, for example by integration into the Emergency STOP circuit and inching mode.

Perfect, gentle gripping

Perfect, gentle clamping
Specimens are always gripped and held perfectly, regardless of the properties of the specimen material.

  • Various operating modes can be selected such as optional continuous gripping, re-tightening in the event of a pressure drop, or wedge gripping with a pressure proportional to the current test load.
  • Operation is possible even at very low pressure.
  • Specimen grip closing speed optionally adjustable via testXpert III.
  • Automatic force zero control reliably protects the specimen from unwanted tensile or compression forces due to material flow or grip deformation during the closing and gripping process.

Intelligent Changeover

Intelligent Changeover
Changing between different tests is easy with testXpert III's intelligent test environment concept. This includes automatic test-specific storage of test parameters and the test environment.

GripControl for short clamping length grips

GripControl for short gripping length specimen grips
The perfect synergy between short-clamping-length grips and GripControl allows optimum gripping of even the smallest, most sensitive specimens.

Stand-alone

The stand-alone power pack is controlled directly by its own remote control with no connection to the testControl electronics. The remote control features the following functions:

  • Grips can be opened or closed individually.
  • Pressure can be set very simply via a dial control.
  • Re-tightening function can also be activated via the remote control.
  • Short cycle times, easy to operate. Two different pumps ensure rapid closing and high pressures. Smooth, fully automatic switching.
