Product Description:

Bosch Rexroth Indramat makes the VT-HNC100-1-11/130. The maximum load impedance the controller can handle without compromising signal integrity or overloading its internal power supply is 500 Ω, which is the specified maximum load resistance. Another well-thought-out component of this controller is the analog output performance. Cleaner analog output is ensured by the residual ripple of ±60 mV, which means minimal post-conversion signal distortion without extra noise components. The controller can fine-tune output voltages with 1.25 mV resolution, which results in better control granularity and smoother actuator response. The deviation from a perfect linear transfer function is shown by the specified non-linearity of 15 mV within ±9.5 V and up to 35 mV at ±10 V. This is important for analog systems because repeatable actuator behavior depends on precise signal mapping. The VT-HNC100-1-11/130 has a base RS232 interface for digital communication that runs at 9.6 KBaud for setup, diagnostics and simple serial communication where robustness comes before speed.

It supports CANopen, INTERBUS-S and Profibus DP up to 12 MBaud protocols, all of which are designed for high-speed industrial communication in complex systems. With these field bus solutions, you can integrate dispersed sensors and actuators with real-time, distributed control across large automation networks. For synchronized multi-axis control, Profibus DP is especially good for deterministic timing and fast polling. INTERBUS-S is compatible with traditional configurations, and CANopen is more suited for adaptive systems. The controller is compatible with many automation infrastructures by supporting multiple protocols.

The input and output processing of VT-HNC100-1-11/130 has clear thresholds and guards. The binary inputs, which can be chosen from 8, 16 or 24 channels, accept logic low signals at ≤5 V and logic high signals at ≥10 V up to the internal supply voltage UO. The outputs replicate this for the same number of channels with logic high up to UO and logic low at ≤2 V. A 50 mA current limit is in place to prevent output stage overcurrent. The controller supports absolute and incremental position feedback. With a frequency limit of 250 kHz and input voltages from 0 to 1 V (low) and 2.8 to 5.5 V (high), incremental transducers provide fast and accurate pulse interpretation. Absolute encoders with various resolutions can use SSI compatibility to capture serial data up to 28 bits with TTL-level reception. Either the UO line or an external 5 VDC supply (±5%) up to 200 mA can power the transducer. Note that inputs are not opto-decoupled, so you need to consider electrical noise reduction and grounding techniques. Two specific 2 V channels with a 30 mA limit are available for inductive sensors to meet the requirements of non-contact positional measuring systems.
