Comprehensive Guide to Linear Actuator Controllers

Yes, speed control is achievable through the actuator's onboard electronics and configurable EEPROM parameters. NV Mechanics Design actuators support output shaft speeds up to 200 mm/sec, adjustable through software commands sent over RS422/RS232. The Windows software utility (DCBL_ABS_Control_Lin_8_1) also allows users to configure speed and motion profiles for specific application requirements.

NV Mechanics Design offers actuators rated to 3,000 msw (meters of sea water) for the Self-Compensated model and 6,000 meters for the Trunion 1000N and 60,000N Force models. These ratings cover the full range from mid-water column operations to full-ocean-depth ROV and subsea infrastructure applications.

The Self-Compensated Linear Actuator supports RS422 (RS485 full-duplex on 4 wires) and RS232 serial communication at 19200 baud, 8-N-1 format, with status broadcast at 10 Hz. The Trunion and 60,000N models use an external resolver feedback interface. All models are compatible with NV Mechanics Design's Windows software utility for configuration and real-time monitoring.

The Self-Compensated model uses an integrated absolute 30-bit multi-turn rotary encoder (14 bits per turn, 16,383 counts/turn) mounted directly on the output shaft, retaining position data between power cycles. The Trunion 1000N and 60,000N Force models use a rotary resolver on the motor shaft for precise, reliable position feedback in subsea environments.

The Trunion 1000N and 60,000N Force actuators are available in Stainless Steel 316 (SST 316) or Titanium construction, both proven for long-term resistance to seawater corrosion. The Self-Compensated model uses a pressure-compensated oil-filled design with all circuitry sealed internally, protecting electronics from the marine environment at depths to 3,000 msw.

The range spans from 1,000N up to 77,500N axial force across the product lineup. The Self-Compensated model delivers 1,000N to 1,500N (220–330 LBS), the Trunion 1000N scales from 1,000N to 77,500N, and the 60,000N Force model delivers up to 50,000N — suitable for light manipulation tasks through to heavy-duty valve actuation and industrial subsea machinery.
