  • VT-HACD-1-1X/V0/1-0-0 SO026-715

  • Rexroth

  • R987212243

  • Substitutional closed-loop control (e.g. position control with superimposed pressure/force control) possible

  • Input for digital measurement system SSI and incremental

  • 6 analog inputs, voltage (±10 V, 0\u202610 V) and current (4\u202620 mA) switchable

  • 3 analog outputs, 1x switchable voltage (±10 V, 0\u202610 V) or current (0\u202620 mA, 4\u202620 mA), 1x voltage (±10 V)

  • Various possible signal linking and switch-over options

  • Enable input and OK output

  • 8 digital inputs

  • 7 digital outputs, configurable

  • Parameterizable ramp function

  • 32 blocks with command values, velocities and controller parameters

  • Adjustment to hydraulic drive by means of area adjustment, characteristic curve correction, overlap compensation, residual velocity logic and zero point correction.

  • ±10 V reference voltage output

  • Serial interface RS232

  • Up to 32 controller cards can be interconnected for parameterization and diagnosis via the local bus

  • PROFIBUS DP, PROFIBUS DP in Motorola format, DeviceNet or CANopen for the communication with a superior control (For CANopen, there is no standard EDS file available as the data is transmitted by the CANopen PDOs.)
