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
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 released.
Terminal UP/DOWN: After the digital input port is set to the corresponding
function, 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.
