Safety and compliance
The ATV9A0C25Q4: Safe Torque Off (STO) is integrated at SIL 3 per IEC 61508 and IEC 13849-1, eliminating the need for an external safety relay on the drive branch for stop category 0. The drive also carries CE marking and complies with IEC 61800-3, IEC 61800-5-1, IEC 61000-3-12, IEC 60721-3, and IEC 61800-5-2. The integrated EMC filter meets category C3 with 300 m motor cable — sufficient for most industrial installations without an external filter.
Fieldbus and I/O expansion
The control block includes dual RJ45 for Ethernet IP/Modbus TCP (10/100 Mbit/s, half/full duplex, auto-negotiation) and a separate RJ45 for Modbus serial (RTU, 4.8 to 38.4 kbit/s, 2-wire RS-485, 1–247 addresses). Three option slots (A, B, C) accept communication modules for Profibus DP V1, PROFINET, DeviceNet, EtherCAT, CANopen (daisy chain RJ45, SUB-D 9, or screw terminals), plus digital/analog I/O or output relay extension modules. Slot B can also host a 5/12 V digital encoder interface, analog encoder interface, or resolver interface.
Cabinet-mount only (IP00 open-chassis — requires IP21 or IP54 enclosure per the standard). Pollution degree 2, operating altitude up to 4800 m with derating above 1000 m. Forced convection cooling, switching frequency adjustable 2.5–8 kHz with derating. Vibration resistance: 1.5 mm peak-peak at 2–13 Hz, 0.5 gn at 13–200 Hz. Shock resistance: 7 gn for 11 ms. Relative humidity 5–95 % non-condensing.
