User Manual of EM730 Series Inverter UP/DOWN, which are handled separately and can be enabled at the same time. The UP/DOWN functions are mainly divided into the keyboard UP/DOWN and terminal 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 the DOWN function by reverse spinning. During the forward or reverse spinning of the digital potentiometer under the 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 Terminal UP/DOWN: After the digital input port is set to the corresponding function, released. terminal control will be enabled. When the UP/DOWN terminal is valid, the offset frequency will increase/decrease at the rate of F12.10 and the final frequency is the set frequency plus offset frequency. The display content of the keyboard remains unchanged during this period.
★ When the keyboard UP and terminal DOWN are valid at the same time, or the 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. 261 Function code Function code name Parameter description Unit Default setting Attribute Mailing address F12.10 UP/DOWN acceleration and deceleration rate 0.00: automatic rate 0.01 ~ 500.00 Hz/s 5.00 〇 0x0C0A F12.11 Options of UP/DOWN offset clearing 0: do not clear 1: clear in non-running state 2: clear when UP/DOWN invalid 3:
