Control character |
V/F Curve (Voltage-Frequency character) |
Base frequency can be set from 5~500Hz arbitrarily, and there are three kinds of curve: constant torque, Dec torque 1 and Dec torque 2. |
Torque Boost |
Manual Setting: 0~20% of rated output, Auto-boost: Automatically boost torque according to output current. |
|
Auto Energy-saving running |
Adjust output voltage and slip compensation properly according to output current, which will make the motor working in highest efficiency. |
|
Acc./Dec time setting |
0.1~6000 seconds can be set continuously, and S type and line type can be selected |
|

|
Voltage stall prevention |
Ensure not over-voltage in Dec process. |
|
Low noise running |
Carrier freq. can be adjusted continuously form 1.5KHz to 15.0KHz, which can reduce the motor's noise furthest. |
|
