Product configuration
| Basic application functions | |
| Low frequency torque boost | The voltage boost and torque boost can increase the low-frequency torque of V/F control and speed sensorless vector control by about 0.1%~30.0% respectively. |
| V/F Curve | Linear type, multi-point type |
| Acceleration and deceleration curve |
Linear or S-shaped acceleration and deceleration; three sets 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; the inching frequency setting range is: 0.0-20.0Hz Inching stop mode: deceleration/free/DC braking |
| Frequency Hopping | You can set 3 frequency hopping points and the corresponding frequency hopping range to prevent the inverter from running within the frequency band. |
| Multi-speed | Up to 15 operating frequencies can be set via 4 logic input ports |
| Input Sum | The algebraic operation result of 2 analog inputs is used as the frequency setting, making the frequency setting more flexible |
| 2 sets of motor parameter switching | Two sets of motor parameters can be set and switched freely to match the currently driven motor |
| Inverter protection | Input/output phase loss protection, underload detection, over-torque protection, undervoltage protection, overvoltage protection, overcurrent protection, overheating protection, phase short circuit protection |
