AC70 VC CONTROL FREQUENCY INVERTER MANUAL OVERVIEW
5
V/F curve
5 kinds curve programmable setting:1 user setting, 1 of linear
characteristic torque curve setting. 3 kinds derating torque
setting( 1.5 power, 1.7 power, 2.0 Power curve )
Accel / Decel. curve
Two kinds curve: line Accel/Decel, S curve Accel/Decel.
4 Aceel/Decel time unit is 0.1s, maximum time 6500.0s
Rated output voltage
Power voltage compensation is available, setting range from 50 to
100%( rated voltage), the output voltage can't over than input
AVR( Auto Voltage Regulation
automatic voltage regulation for keeping output voltage stable when
fluctuation of grid
Auto energy saving running
Optimized the output voltage according the load to achieve energy
saving
Auto current limit
Auto current limit during running mode to avoid trip occurs
frequently
Momentary Power Loss with
no stop running function
To achieve continuous running with regenerative enery and DC bus
voltage regulation when momentary power loss
