Basic application functions

Low-frequency torque boost

Through voltage boost and torque boost, the low-frequency torque of V/F control and speed sensorless vector control can be increased by about 0.1%~30.0%

V/F curve

Linear type, multi-point type

Acceleration/deceleration curve

Linear or S-shaped acceleration and deceleration: three groups of acceleration and deceleration time: acceleration and deceleration time range: 0-3200s

Automatic voltage regulation (AVR)

When the grid voltage changes, it can automatically keep the output voltage constant

Built-in PID

Closed-loop control system that can easily realize process control

DC braking

DC braking range: 0.0Hz-maximum frequency; braking time: 0.0s-20.0s; braking action current value: 0%-100%

Jog control

The motor can be started and stopped immediately; jog frequency setting range: 0.0-20.0Hz; jog stop mode: deceleration/free/DC braking

Frequency hopping

Three hopping frequency points and corresponding hopping frequency ranges can be set to prevent the inverter from running in this frequency band

Multi-speed

Up to 15 can be set through 4 logic input ports =Operating frequency

Input summing

Use the algebraic operation result of 2 analog inputs as frequency setting, making frequency setting more flexible

Switching between 2 sets of motor parameters

Two sets of motor parameters can be set and switched freely to match the current driven motor

Inverter protection

Input/output phase loss protection, underload detection, over torque protection, Undervoltage protection, overvoltage protection, overcurrent protection, overheating protection, phase-to-phase short circuit protection

Motor protection

Motor thermal protection, Motor current limit, Motor overload, Motor short circuit

Electrical Characteristics

Input voltage

Three-phase AC, 380-480V, 50/60Hz or single-phase AC, 200-240V, 50/60Hz

Output voltage

0-100% input voltage, 0.5Hz-400Hz

Control mode

Constant torque V/F, quadratic load V/F, sensorless vector control, energy-saving mode

Switching frequency

1.5kHz-12kHz

The automatic switching frequency adjustment function can be set: when the temperature rises, the switching frequency is automatically reduced

When the temperature returns to normal, the switching frequency returns to the initial value

Over-current capability

150% rated output current 60s, 200% rated output current 2s
