Technical Parameters

Core Advantages

1. Heavy-Duty Process Control with 150% Overload

The ATV930D30N4 is engineered for constant torque applications where full torque is required across the entire speed range. Its 150% overload capability for 60 seconds (heavy duty) ensures reliable operation during motor starting, load impacts, and dynamic braking sequences . This makes it the correct choice for cranes, hoists, extruders, mixers, and other demanding machinery where the ATV630 (variable torque) would be insufficient.

2. Integrated Braking Chopper for High-Inertia Loads

Unlike the ATV630 series, the ATV930 includes a built-in braking chopper as standard . This enables the drive to dissipate regenerative energy through an external braking resistor, providing controlled deceleration for high-inertia loads such as centrifuges, flywheels, and crane hoists without requiring additional braking modules. Braking resistor connection is made via the PA/+ and PB terminals .

3. Safe Torque Off (STO) for Functional Safety

The drive includes STO safety function certified to SIL 3, enabling implementation of functional safety systems without external safety contactors. This reduces wiring complexity, saves cabinet space, and simplifies safety system design .

4. Comprehensive Connectivity and Encoder Options

With native EtherNet/IP, Modbus TCP, and Modbus Serial built in, the ATV930D30N4 integrates seamlessly into modern plant networks . Slot B accepts optional encoder interface cards including 5/12V digital encoder, analog encoder, and resolver interfaces for closed-loop vector control applications requiring precise speed or position feedback .

5. Asset Monitoring and Process Protection

The drive features drift monitoring and asset monitoring functions that track equipment health and alert operators to potential issues before they cause unplanned downtime . Combined with the Stop and Go function, which reduces energy consumption during idle periods, the ATV930 delivers both reliability and efficiency.

6. Environmental Transparency

Schneider Electric publishes lifecycle environmental data for this product, including a total carbon footprint of 10,882 kg CO2 eq, 96% ASI-certified metal content, and 85% recyclability potential . The packaging uses recycled cardboard with minimum 70% recycled content.

Frequently Asked Questions (FAQ)

Q1: What is the Schneider Electric ATV930D30N4?

It is a heavy-duty Altivar Process ATV930 variable frequency drive rated at 30 kW (40 HP) for normal duty operation. It is designed for constant torque and high dynamic applications including cranes, hoists, extruders, and mixers .

Q2: What is the difference between ATV930 and ATV630?

ATV630 is the process variable torque variant for pumps, fans, and compressors. ATV930 is the heavy-duty constant torque variant for cranes, hoists, extruders, and mixers. The ATV930 offers 150% overload for 60 seconds, while the ATV630 offers approximately 120% . The ATV930 also includes an integrated braking chopper as standard.

Q3: What is the power rating of this drive?

The ATV930D30N4 is rated at 30 kW / 40 HP for normal duty and 22 kW / 30 HP for heavy duty .

Q4: Does this drive include a braking chopper?

Yes. The ATV930D30N4 includes an integrated braking chopper as standard . For applications requiring controlled deceleration of high-inertia loads, an external braking resistor is connected to the PA/+ and PB terminals .

Q5: What communication protocols are supported?

Standard protocols include EtherNet/IP, Modbus TCP, and Modbus Serial. Optional communication modules enable Profibus DP V1, PROFINET, DeviceNet, EtherCAT, CANopen, and Ethernet Powerlink .

Q6: Does this drive include a safety function?

Yes. The ATV930D30N4 includes STO (Safe Torque Off) certified to SIL 3, enabling implementation of functional safety systems without external contactors .

Q7: What encoder interfaces are available?

Slot B accepts optional encoder interface cards including 5/12V digital encoder, analog encoder, and resolver interfaces for closed-loop vector control .

Q8: What is the protection class of this drive?

The ATV930D30N4 has an IP21 protection class with UL Type 1 conformity, making it suitable for wall mounting in industrial environments .

Q9: What is the Stop and Go function?

The Stop and Go function automatically places the drive into a low-energy standby state when there is no demand, reducing energy consumption during idle periods .

Q10: What motors are supported?

The ATV930D30N4 supports asynchronous motors, permanent magnet synchronous motors, and synchronous reluctance motors .

Q11: Can I replace an ATV71 with this drive?

Yes. The ATV930 is the designated replacement for the ATV71 series. However, parameter systems differ significantly, and encoder/communication cards are not interchangeable—recommissioning and testing are required.

Q12: What should I verify before ordering?

Always verify the exact part number (ATV930D30N4 vs. ATV930D30N4Z for IP20), confirm your motor power and duty cycle requirements (normal vs. heavy duty), ensure your supply voltage matches (380-480 V AC, 3-phase), and check whether you require encoder feedback (Slot B option) or additional communication protocols.
