Product Description:

The FCS01.1E-W0015-A-04-NNBV is a frequency converter from Bosch Rexroth Indramat’s FCS Frequency Converters series. It is intended to modulate the voltage and frequency delivered to three-phase motors in automated machinery, allowing speed and torque to match process demands while operating from the plant’s standard power bus. The converter uses internal air cooling through an integrated blower and is intended for cabinet mounting in enclosed electrical panels.

This model delivers a rated shaft power of 3 kW and accepts a supply of 3 x AC 380 to 480 V on a three-phase network. Output frequency can be adjusted up to 400 Hz, giving flexibility for both standard and high-speed motors, while the drive can source up to 15 A of phase current under full load. The intermediate circuit is held at 720 V, which supports dynamic torque changes without significant bus sag. Pulse-width modulation can be selected between 3 kHz and 16 kHz so acoustic noise can be balanced against switching losses. The unit measures 98 mm wide, 178 mm deep, and 241 mm high, with a 275 mm mounting length. It is design version 1 and line 1, and it uses a feeding power-supply configuration.

An external braking resistor can be connected, and the built-in transistor channels dissipative energy to supply 0.4 kW continuously and up to 5.2 kW during short decelerations. The drive withstands momentary overloads of 200% for 5 seconds and 150% for 60 seconds, enabling rapid starts or stops without nuisance trips. Its enclosure carries an ingress rating of IP20, making field wiring and ventilation straightforward when installed inside a closed cabinet. A dedicated 24 V DC control supply maintains logic and brake functions during main-power interruptions, promoting orderly shutdown of connected motion axes.
