Key Features
Rated power is 4.00 kW | 5.00 hp for LO and 3.00 kW | 4.00 hp for HO. LO supports 150% for 3s, 110% for 57s and 100% for 240s; HO supports 200% for 3s, 150% for 57s and 100% for 240s.
Input is 3 AC, 380 … 480 V +10 % -20 %, with a line frequency of 47 … 63 Hz.
The unfiltered external 24V I/O interface has 6 standard digital inputs, 1 fail-safe digital input, 1 relay changeover contact, 1 transistor output, 1 differential input and 1 non-isolated analog output.
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. Communication is USS/MODBUS RTU.
Line-side, motor-end and DC link connections use plug-in screw terminals. The DC link accepts 1.00 … 2.50 mm2 (AWG 18 … AWG 14) conductors and has a maximum line length of 15 m (49.21 ft).
Protection is IP20 / UL open type. Frame size is FSA; dimensions are 73 mm (2.87 in) width and 203 mm (7.99 in) depth, with 1.70 kg (3.75 lb) net weight.
