VD560 Series Inverter User Manual Parameter Description

5: Communication setting
Define the frequency upper limit source. Frequency upper limit can be from digital setting (F0-12),
also from the analog input channel. When use analog input set the frequency upper limit, 100% of the
analog input set corresponding F0-12.
For example at the scene of the winding control using torque control mode, in order to avoid material
break appear “galloping” phenomenon, can use analog set the frequency upper limit, when inverter
running to the frequency upper limit value, the frequency inverter in frequency upper limit running.

When the frequency upper limit for analog or PULSE setting, F0-13 as the offset of set value, the
offset frequency and F0-11 set frequency upper limit value superposition, as the final frequency upper
limit set value.

○
When frequency instructions is lower than the frequency lower limit of F0-14 set, inverter can stop,
running at frequency lower limit or zero speed, what running mode can be through the F1-17 (set
frequency is lower than the frequency lower limit running mode) set.

●
The parameter used to determine all the resolution of the function code associated with the
frequency.
When frequency resolution is 0.01Hz, the maximum output frequency of VD560 is 600.00Hz.

This parameter is only valid when frequency source for the digital setting.
Used to determine the keypad key ▲,▼ or terminal UP/DOWN action, adopt what way correction set
frequency, namely the target frequency is increase or decrease based on the running frequency, or
increase or decrease base on the set frequency.
The difference between two kinds of settings, evident when inverter in the deceleration process,
namely if the running frequency of inverter is different with the set frequency, the parameter different
selection difference is very big.

○
The function is only valid when frequency source for the digital setting.
“No memory” refers to the frequency inverter after downtime, digital set frequency values revert to
F0-09 (preset frequency) value, keypad key ▲,▼or terminal UP/DOWN to correct the frequency is
zero.
“Memory” refers to the frequency inverter after downtime, digital set frequency keep set frequency for
the last moment downtime, keypad key ▲,▼or terminal UP/DOWN to correct the frequency is remain
