MVC3003-4030 AC servo drive module

MVC3003-4030 AC servo drive module
This is a high-performance AC servo drive module produced by Converteam (now part of Nidec/Nidec Group), belonging to the MVC3003 series, widely used in the field of industrial automation.

core parameters
Project specifications
Brand Converteam (original imported)
Rated power 3kW (MVC3003-4030PP model clearly marked)
Control method: Vector control/IPM sine wave PWM
Speed control range 1:100000
Torque limit 0-220% rated torque
Speed command signal 0~± 10V (analog), corresponding to 0~± 2000rpm
Feedback signal incremental encoder 2048P/R (standard)
Protection functions include overcurrent, short circuit, overspeed, overheating, overvoltage, and undervoltage
In the model, “30” represents the 3kW power level, and “40” represents the 40A current level. This is the naming convention for this series (there are also specifications such as 3015, 5030, 5050 in the same series).

Key Features
Characteristic Description
Advanced control algorithms for high-precision control, providing high-resolution position, velocity, and torque control
Dual redundant bus and dual optical ports achieve dual fiber ring redundancy. In case of fiber failure, the network link can be rebuilt within 10ms, with self-healing protection
High dynamic response is suitable for situations with high precision and high dynamic response
Torque/speed monitoring output DC 1mA meter signal for external monitoring
Typical application areas
Domain Usage
🏭 Mechanical manufacturing, various types of machine tools, feed axis drive
📦 High precision positioning and high-speed control in packaging printing
💨 Wind power direct drive permanent magnet wind turbine drive (Converteam is a leading global supplier)
🛢️ High reliability drive under harsh working conditions in metallurgy/petrochemicals
Wiring points (refer to the universal interfaces of the same series)
Terminal function
R/S/T three-phase AC power supply 220V (-15%~+10%, 50Hz)
U/V/W motor three-phase output
+DIF/- DIF speed command analog input (0~± 10V)
PR (CN2-24) driver enable (command is valid after+24V is turned on)
+ENABLE/- ENABLE forward/reverse enable (also serves as a normally closed contact for limit switches)
READY (CN2-12) servo ready signal
P/B regenerative discharge resistor terminal (external discharge resistor must be connected)
CN3 encoder connection (A/B/Z phase signal+5V)
⚠️ Important: The load inertia converted to the motor shaft end should be ≤ 4 times the motor inertia, otherwise an overvoltage alarm (ALM light on) will be triggered during deceleration/braking.
