What this 175 hp VFD brings to a 600 V line
The ATV9B0C16T6 is a modular Altivar Process 900 drive rated 175 hp at 600 V normal duty and 150 hp heavy duty, with corresponding line currents of 142 A and 121 A at 600 V. It handles synchronous and asynchronous motors, and the switching frequency is adjustable from 2 to 4.9 kHz with a derating factor above the base setting.
SIL 3 STO and control supply layout
The control board provides 24 V DC (19...30 V) for digital inputs, a separate 10.5 V DC reference supply for a 1 to 10 kOhm potentiometer, and a dedicated 24 V DC (21...27 V) supply for the STO and digital input circuits — three isolated supplies on the terminal block.
Fieldbus slots and cabinet integration
Three option slots (A, B, C) accept communication modules for Profibus DP V1, PROFINET, DeviceNet, CANopen, EtherCAT, plus digital/analog I/O and encoder interface cards — the drive ships without a fieldbus card fitted, so you order the slot module that matches your network. Mounting is cabinet-integrated with IP00 protection (UL type 1 or 12 when enclosed), and the EMC filter is integrated for 300 m cable runs at IEC 61800-3 category C3.
Compliance and lifecycle
The drive carries CE marking and complies with IEC 61800-3, IEC 61800-5-1, IEC 61508, IEC 13849-1, and UL 61800-5-1 — covering EMC, safety, and North American installation requirements.
