A 10.5 V DC ±5 % reference supply is available for a 1 to 10 kΩ potentiometer. The STO function is rated SIL 3, and the drive also includes thermal protection, motor phase break detection, and overcurrent/overvoltage protection on both the drive and line sides. ## Fieldbus and I/O expansion The drive ships with dual RJ45 ports for Ethernet IP/Modbus TCP and one RJ45 for Modbus serial. Slot A accepts communication modules for Profibus DP V1, PROFINET, DeviceNet, EtherCAT, or CANopen (RJ45, SUB-D 9, or screw terminals). Slots A, B, and C accept digital/analog I/O extension modules and output relay modules; Slot B also accepts encoder interface modules (5/12 V digital, analog, or resolver). Modbus serial runs at 4.8 to 38.4 kbit/s, RTU frame, addressing 1...247 slaves. ## Mounting and environmental Cabinet-mount design, IP00 (intended for IP21 or IP54 cabinet integration). Forced-convection cooling. Switching frequency adjustable from 2 to 8 kHz with derating above 2.5 kHz. Operating altitude up to 4800 m with derating above 1000 m. Vibration resistance 1.5 mm peak-to-peak at 2...13 Hz, 0.5 gn at 13...200 Hz. Shock resistance 7 gn for 11 ms. Pollution degree 2 per IEC 61800-5-1.","metaTitle":"Schneider ATV9A0C20T4 Altivar Process ATV900, 300 HP at 480","metaDescription":"Schneider ATV9A0C20T4 Altivar Process ATV900 drive, 300 hp at 480 V normal duty, 250 hp heavy duty.
