Product Description:
The 8I84T401100.010-1 Frequency Inverter is designed for industrial grade motor control. It delivers high performance and operational reliability. The unit supports a broad input voltage and frequency range.
The 8I84T401100.010-1 frequency inverter from B & R Automation accepts 3 phase input voltages from 380 V AC (− 15 %) to 480 VAC (+ 10 %) and operates on 50 to 60 Hz input frequency. It includes an integrated EMC filter to reduce conducted interference. The output frequency ranges from 0.5 to 599 Hz. It supports a nominal clock frequency of 4 kHz that is adjustable from 1 kHz to 16 kHz. It delivers short term overload torque of 170 % for 60 seconds and up to 220 % for 2 seconds. When using a braking resistor, braking torque reaches 150 % of the motor's rated torque. Without the resistor, braking torque remains at 30 %. The shielded motor cables may extend up to 50 meters while non shielded cables can reach 100 meters. The device supports both flux vector control (FVC) with encoder and sensorless flux vector control (SFVC). The 8I7 ACOPOS series inverter features voltage/frequency (V/f) control with 2 or 5 point characteristic curves and ENA energy adjustment for asymmetrical loads.
The safe input of the 8I84T401100.010-1 frequency inverter for power removal uses a switching threshold of less than 5 V for low and more than 15 V for high. The electrical isolation is available between input and inverter but not between input to input. The unit has one safe input channel operating at a nominal 24 V DC with a response time of less than or equal to 100 ms. The input impedance is 1.5 kΩ and the input circuit type is sink.
