AC690+ Series – Advanced AC Drives by Parker
The AC690+ series is a versatile range of AC drives designed to meet the requirements of all variable speed applications — from simple single-motor speed control to sophisticated multi-drive systems.
At its core is a powerful 32-bit microprocessor-based motor control model providing exceptional dynamic performance.
Multiple communication and control options allow you to tailor the drive precisely to your application needs.
Available ranges:
• 380–500V 3-phase, 0.75–355kW
• 220–240V 1/3-phase, 0.75–55kW
⚙️ Features
The AC690+ can be configured for three operating modes:
-
- Open-loop (V/F) control: Ideal for basic motor speed control or parallel-driven motors. Quick setup and plain-text display ensure easy, trouble-free startup.
- Sensorless vector control: Uses MRAS (Model Reference Adaptive System) for high starting torque and accurate speed regulation without external feedback devices.
- Closed-loop vector control: Achieved by adding an encoder feedback module, providing 100% full-load standstill torque and highly dynamic speed control (up to 45Hz bandwidth).
