Product Description:

The FECG01.1-90K0-3P660-A-RN-NNNN-01V01 is a frequency converter produced by Bosch Rexroth Indramat in the FEC Frequency Converters series. This three-phase device is used in general automation tasks, where it conditions power to regulate induction motor speed and torque. By delivering synthesized variable frequency from a fixed supply, the unit helps match conveyor, pump, and process equipment loads without mechanical adjustments. The design belongs to the first generation of the platform and is cataloged as design version 1.

Internally, the converter uses a V/F control mode that adjusts stator voltage in proportion to output frequency, providing predictable magnetizing flux across the speed range. Continuous output reaches 90 kW, and frequency can be trimmed in digital steps of 0.01 Hz for precise setpoint tuning. A high overload characteristic supports momentary surges to 200% for 1 second and 150% for 60 seconds, helping the drive handle rapid accelerations. Operation is supported by forced, temperature-controlled cooling, which increases airflow only when required. Interface resources include 3 analog inputs, 8 digital inputs, 1 encoder input, 2 analog outputs, 2 open-collector outputs, 1 relay output, and 1 frequency output, enabling closed-loop or sequence-controlled operation. This mix of terminals allows analog reference handling, discrete status exchange, and encoder-based feedback on the same unit. The housing is mechanical size 6 with a 455 mm width, allowing panel integration alongside standard control gear.

The enclosure has an IP20 protection class for installation inside a switch cabinet at altitudes up to 1000 m without derating. Starting heavy loads is supported by a startup torque of 150% at 5 Hz, while long-term speed stability is indicated by a ratio of 1:100. An external brake chopper handles regenerated energy during deceleration, and the unit arrives without a potentiometer, so all references are provided through field wiring. That arrangement helps the drive manage deceleration energy from overhauling or high-inertia loads without relying on an internal braking circuit.
