User Manual of A90 Series Inverter The UP/DOWN functions are mainly divided into the keyboard UP/DOWN and terminal UP/DOWN, which are handled separately and can be enabled at the same time. Keyboard UP/DOWN: It is valid in the Level 0 monitoring menu. When the current setting is not the digital potentiometer setting, the UP function can be performed by forward spinning of the digital potentiometer via the keyboard and During the forward or reverse spinning of the digital potentiometer under the the DOWN function by reverse spinning. monitoring menu, the offset frequency will increase/decrease at the rate of F12.10, the keyboard will display “F18.01:
set frequency”, and the final frequency will be the set frequency plus offset frequency. The keyboard will have the normal display 2 s after the key is released. Terminal UP/DOWN: After the digital input port is set to the corresponding When the UP/DOWN terminal is valid, the offset frequency will increase/decrease at function, terminal control will be enabled. the rate of F12.10 and the final frequency is the set frequency plus offset frequency. ★ When the keyboard UP and terminal DOWN are valid at the same time, or the The display content of the keyboard remains unchanged during this period.
keyboard DOWN and terminal UP are valid at the same time, despite of the same acceleration and deceleration rates, the offset frequency will fluctuate because of different valid moments. This is a normal phenomenon. The A90 series inverter has a watt-hour meter function (see the description of the function codes F18.18 and F18.19). The user can set the current function code to 1 to clear the current count. 219 invalid F12.12 Options of UP/DOWN power-down saving of offset 0: do not save 1: save (valid after the offset is modified) 0 ○ Function Function Default Parameter description Unit Attribute code code name setting F12.13 Power meter resetting 0: do not clear 1: clear 0 ●
