| CONTROL FUNCTION | |
| Freq dissolutions | Digital setting: 0.01Hz; Analog setting: highest frequency×0.1% |
| Output frequency accuracy | 0.1Hz |
| V/F curve | V/F curve can be arbitrarily set to meet the needs of various loads |
| Torque increase | Automatically rise torque up, according to output current it auto rise the torque up. Manually rise torque up, scope: 0~20% |
| Multi-function input terminal | There are 4 multi-functional input terminals, achieve functions as following: 15 speed control, program running 4 acceleration/deceleration switch, UP/DOWN function, emergency stop, etc |
| Multi-function output terminal | There is one multi-function output terminal, to achieve function as following: indications of operating, zero speed, external abnormalities, program operation and alarm output |
| Acc./Dec. Time setting | 0~999.9s can be set separately to Acc./Dec. time |
| OTHER FUNCTION | |
