Product information
Overview
Key Features
- Rated power and overload: Output power is 5.50 kW at low overload and 4.00 kW at high overload. Low overload supports 150% for 3s, 110% for 57s, and 100% for 240s; high overload supports 200% for 3s, 150% for 57s, and 100% for 240s.
- Input and output ratings: Input: 3 AC, 380 … 480 V +10 % -20 %, 47 … 63 Hz. Output: 3 AC, 400V IEC | 480V NEC, with maximum output current of 17.60 A.
- Control and feedback: The converter supports 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.
- I/O and safety: The interface has 6 standard digital inputs, 1 fail-safe digital input, 1 relay changeover contact output, 1 transistor output, 1 differential analog input, and 1 non-isolated analog output. Safe Torque Off is integrated.
- Communication and protection: Fieldbus: PROFIBUS DP. Protection: IP20 / UL open type. The integrated fan provides air cooling.
- Connections and dimensions: Line-side and motor-end connections use plug-in screw terminals. Frame size is FSB; dimensions are 100 mm width and 203 mm depth. Maximum shielded motor cable length is 150 m (492.13 ft).
