Product Description:

The FECP01.1-90K0-3P660-A-RN-NNNN-01V01 frequency converter is built by Bosch Rexroth Indramat and belongs to the FEC Frequency Converters series. As a first-generation, design 1 unit, it serves pump and fan drives in automated systems. It provides variable voltage and frequency so that flow or airflow can be matched to real-time demand, which helps the motor run more smoothly as operating conditions change.

With a mechanical size 6 housing that measures 455 mm in width, the converter supplies 90 kW of rated output power. It accepts a three-phase line at 50 to 60 Hz and recreates the waveform in steps as fine as 0.01 Hz. Closed-loop analog references are held within 0.05% of command, while digital accuracy is 0.01%. The assembly is classified as IP20, so it requires installation inside a protected cabinet and protection from direct contact. An external brake chopper can be connected, and user-selectable braking time from 0 to 10 s helps manage deceleration energy. The DC brake can be triggered from 0 to 60 Hz, and the three-phase topology helps maintain balanced loading. The converter can operate at sites up to 1000 m above sea level with relative humidity below 90% and without condensation.

For short overloads, the drive tolerates 120% for 60 seconds, and for extended duty it withstands 105% for 60 minutes before derating. Start-up sequences benefit from a reserve of 150% at 5 Hz, delivered through the configurable V/f control law, which supports low-speed torque during ramp-up. Because there is no internal potentiometer, speed commands are supplied externally through the control system. The power stage is described as durable, and the available application presets support pump and fan operating profiles. This arrangement suits installations that use remote speed references rather than local manual adjustment.
