Key Features
Low overload: 5.50 kW at 150% for 3s, 110% for 57s, and 100% for 240s. High overload: 4.00 kW at 200% for 3s, 150% for 57s, and 100% for 240s.
Input: 3 AC, 380 … 480 V +10 % -20 %, 47 … 63 Hz. Output: 3 AC, rated voltage 400V IEC | 480V NEC, with output frequency up to 0 … 550 Hz for V/f control.
The interface has 6 standard digital inputs, 1 fail-safe digital input, 1 relay changeover contact, 1 transistor output, 1 differential analog input, and 1 non-isolated analog output. Communication: PROFIBUS DP.
Supported control includes V/f linear / square-law / parameterizable, V/f with flux current control (FCC), V/f ECO linear / square-law, and sensorless vector control. Vector control with sensor and encoderless torque control are not supported.
Line-side, motor-end, and DC-link connections use plug-in screw terminals. The DC link supports a maximum line length of 15 m (49.21 ft); PE connection is on the housing with an M4 screw.
Protection: IP20 / UL open type. Frame size: FSB. Dimensions: 100 mm width and 203 mm depth. Net weight: 2.30 kg (5.07 lb).
