Schneider Electric ATV930C22N4 Altivar Process ATV900 Variable Speed Drive

Schneider Electric ATV930C22N4 Altivar Process ATV900 Variable Speed Drive

The Schneider Electric ATV930C22N4, also cataloged as the ATV930 Variable Speed Drive, operates as a dedicated hardware component for 3-phase asynchronous and synchronous motor speed regulation within industrial process control networks.

Hardware Specifications

Deterministic Industrial Network Connectivity and I/O Density

The ATV930C22N4 backplane integrates dual RJ45 Ethernet ports supporting deterministic EtherNet/IP and Modbus TCP protocols at 10/100 Mbit/s full-duplex operation. The drive accepts slot-based expansion interfaces (Slot A, B, and C) to scale digital and analog I/O density alongside dedicated encoder feedback boards (5/12 V digital, analog, or resolver). Dedicated dual Safe Torque Off (STOA/STOB) discrete inputs operating at 24 VDC provide SIL3 / PL e compliant fail-safe hardware execution directly at the drive power stage without external isolation contactors.

Frequently Asked Questions

Q: What are the main line side and motor side power terminal conductor size limits?

A: The line side, motor output, and DC bus power connections utilize screw terminals designed for dual conductors up to 2 x 150 mm2 (2 x 350 kcmil).

Q: What is the required clear mounting orientation and air flow volume for heat dissipation?

A: The unit must be mounted vertically within +/- 10 deg on a flat surface. The internal forced-convection cooling system requires an unobstructed air flow volume of at least 860 m3/h.

Q: What are the integrated digital input logic voltage threshold parameters for PLC interfacing?

A: For positive logic (source), logic state 0 corresponds to < 5 VDC and logic state 1 corresponds to > 11 VDC at an input impedance of 3.5 kOhm.

Field Installation Guidelines

• Mounting & Clearance: Secure the IP00 enclosure strictly in a vertical orientation (+/- 10 deg) on a load-bearing wall or enclosure backplate capable of supporting 172 kg. Maintain adequate vertical clearance above and below the cooling heatsink to allow unrestricted forced-air convection of 860 m3/h.
• Power Line & Grounding: Connect incoming 3-phase line supply (380 to 480 VAC) and motor leads to the designated screw terminals using dual 150 mm2 cable runs where applicable. Ensure high-frequency low-impedance ground bonding between the drive chassis, EMC plate, and motor frame to comply with IEC 61800-3 limits.
• Control & Signal Wiring: Route discrete control (0.5 to 1.5 mm2) and analog I/O wiring in separate grounded metallic conduits away from three-phase AC power cables. Connect cable shields to the grounding clamp at a single termination point to prevent ground loop noise on 4-20 mA and 0-10 VDC channels.
