Core Features & Benefits
Advanced Control Algorithms
The EDB-10AMA incorporates current feed-forward control, speed observer, and inertia observer functions. These advanced features significantly improve response performance by reducing overshoot and minimizing settling time.
Control Mode Switching
The drive supports flexible control mode switching, allowing operators to change between position, speed, and torque control modes based on application requirements. By setting appropriate switching parameters, users can effectively reduce overshoot and adjustment time.
Three Control Modes
- Position Control - Precision positioning for CNC machines, pick-and-place systems, and indexing applications
- Speed Control - Velocity-based control for conveyors, spindles, and winding applications
- Torque Control - Force/tension control for pressing, winding, and tensioning systems
300% Overload Capacity
The EDB series features 3x rated current overload capacity, ensuring reliable operation during demanding acceleration and deceleration phases. This high overload capability handles sudden load fluctuations and high-torque demands without stalling.
MODBUS Communication
Equipped with RS-485 communication supporting MODBUS protocol, the EDB-10AMA integrates easily into existing control systems. This enables parameter setting, status monitoring, and real-time control from a host controller.
Built-in Regenerative Resistor
The drive includes an internal regenerative resistor to handle deceleration energy. For high-inertia or high-cycle applications, users can connect external regenerative resistors for unlimited operation.
Brake Interlock Output
The drive features a brake interlock output signal specifically designed for holding brake control. Users can configure brake waiting speed and brake waiting time - particularly important for vertical loads where load holding is critical when power is removed.
User-Friendly Setup
- On-board digital operator for parameter setting and status monitoring
- PC connection via RS-232 for advanced configuration using Estun software
- Software-programmable output signals (4 groups, alarm signals customizable)
Flexible Stop Methods
Multiple stop methods available for different application needs:
- Dynamic braking (regenerative)
- Reverse braking
- Reverse braking with zero clamping
- Free stop
