Product information
Overview
Key Features
- Low- and high-overload ratings: Rated power is 7.50 kW at low overload and 5.50 kW at high overload. Low overload: 150% for 3s, 110% for 57s, 100% for 240s; high overload: 200% for 3s, 150% for 57s, 100% for 240s.
- 3 AC electrical ratings: Input: 3 AC, 380 … 480 V +10 % -20 %, 47 … 63 Hz. Output: 3 AC, with rated current of 16.50 A at low overload and 12.50 A at high overload.
- Control and safety functions: Supports V/f linear / square-law / parameterizable, V/f with flux current control (FCC), V/f ECO linear / square-law, and sensorless vector control. Safe Torque Off is integrated.
- I/O and communication: Unfiltered interface with 6 standard digital inputs, 1 fail-safe digital input, 1 relay changeover output, 1 transistor output, 1 differential analog input, and 1 non-isolated analog output. Communication: PROFIBUS DP.
- Connections and protection: Line-side, motor-end, and DC-link connections use plug-in screw terminals. Protection: IP20 / UL open type; frame size: FSB.
