Product Description:

Bosch Rexroth Indramat makes the VT-MUXA2-1-10/V0/1A. Ripple voltage—the unwanted AC component that rides on a DC supply—is a problem DC-powered systems face due to inadequate rectification. The VT-MUXA2-1-10/V0/1A controller tackles this issue by limiting the maximum residual ripple to 2.5 V peak-to-peak across a wide frequency range of 40 Hz to 400 Hz. That ripple level can skew analog control signals or disrupt PWM switching cycles if not managed. By limiting that ripple size, the controller protects signal integrity and ensures the actuator response remains predictable even in the presence of modest power quality issues. That means it can work with suboptimal power systems without needing extra conditioning components in the power supply infrastructure design. And that reduces the effects of high-frequency interference, too.

One of the key benefits of the VT-MUXA2-1-10/V0/1A is its versatility in signal interfacing. It can handle command values in both voltage (0 to ±10 V) and current (4 to 20 mA) forms. Dual-solenoid topologies give you symmetrical functioning over ±100%, while single-solenoid devices interpret input across a linear range of 0-100%. The high differential input resistance of 200 kΩ for voltage inputs helps keep the burden off upstream signal sources and maintain signal integrity. The integrated 100 Ω load resistance for current inputs ensures the right voltage development for signal processing-you need that for precise industrial analog signal interpretation. The drive controller can be easily integrated into systems using either voltage-based or current-loop signal transmission. That's because of its characteristics, which also make it compatible with a wide variety of industrial sensors and controllers.

The controller's solenoid output stage is designed to withstand peak currents of up to 2.7 A and provide short-circuit protection to avoid damage from wiring errors or actuator failure. PWM output control uses an internal switching frequency that can be adjusted between 95 Hz and 505 Hz. That lets designers customize the actuation response and thermal behavior of solenoids. The device can be installed across large systems without sacrificing power supply or signal timing, thanks to high line impedance. You can install it up to 50 meters away using 1.5 mm² conductors. Designers can fine-tune dynamic response profiles with configuration options like zero-point shift (±10%), command scaling (70-110%), ramp time (0.01-30 s), and step level adjustment (0-50%). Those adjustments help prevent mechanical shock or overshoot in precision systems and support smooth acceleration or deceleration suited to specific machine needs.
