Description
MICROMASTER 440 Inverter without filter. Digital microprocessor control. Flux current control for improved dynamic response and optimized motor control. Latest IGBT technology. Linear V/F characteristic. Quadratic V/F characteristic. Multipoint characteristic (programmable V/F characteristic). Flying restart. Slip compensation. Automatic restart following mains failure or fault. User-definable function blocks for logic and arithmetic operations. Kinetic buffering. Positioning ramp down. High-grade PID controller for simple process control (auto-tuning). Programmable acceleration or deceleration times from 0 to 650 seconds. Ramp smoothing. Fast current limit for trip-free operation. Fast, repeatable digital input response time. Fine adjustment using a high-resolution 10-bit analog inputs. Compound braking for controlled rapid braking. Integrated brake chopper (for 0.12 to 75 kW inverters). Four skip frequencies.
