VT-15020 S1X/HNC-CPU

The Bosch Rexroth Indramat VT-15020 S1X/HNC-CPU is a high-performance digital axis controller in the VT-HNC Digital Axis Controllers series designed for demanding industrial automation environments. This controller features 2 channels of precision Analog Output Channels with an Output Resolution of 1.25 mV to ensure fine-grained control over actuator positioning. It operates over a wide Operating Voltage range of 18 to 36 VDC, making it compatible with common industrial power supplies. The device supports flexible I/O configurations with up to 24 Switching Inputs or 24 Switching Outputs, each selectable across 8/16/24 channels for system scalability. Early integration is simplified by including the part_number VT-15020 S1X/HNC-CPU alongside the manufacturer Bosch Rexroth Indramat and the series VT-HNC Digital Axis Controllers in procurement documentation.

Performance and technical feature highlights include Output Current (normalized) of 4 to 20 mA and Output Current (non-normalized) up to ±23 mA, accommodating both standard and extended driver requirements. The controller maintains a maximum Residual Ripple of ±60 mV when driving Load Resistance up to 500 Ω, ensuring signal integrity under load. Non-linearity is tightly controlled to 15 mV within –9.5 V to +9.5 V and peaks at 35 mV when operating near the –10 V to –9.5 V and +9.5 V to +10 V thresholds. Integration into varied automation networks is achieved through a Standard Serial Interface (RS232 at 9.6 kBaud) and optional Communication Interfaces including Profibus DP (≤12 MBaud), CANopen, and INTERBUS-S. These multi-interface support options facilitate direct connection to PLCs, motion controllers, and HMI systems without additional protocol converters.

Built for reliability in industrial settings, this controller operates over an Operating Temp Range of 0 to 50 °C and can be safely stored between –20 to +70 °C (Storage Temp Range). Its compact form factor (variant dimensions of 71 × 155 × 204 mm) allows installation in densely populated control cabinets and on modular DIN rails. With dual-channel input capability and inherent protection against high non-linearity voltage excursions, the VT-15020 S1X/HNC-CPU ensures consistent performance in servo loops, feed systems, and gantry applications. As part of Bosch Rexroth Indramat’s automation portfolio, it is ideally suited for precision motion control tasks in packaging machinery, robotics, and CNC systems where dependable operation and easy fieldbus integration are paramount.
