Pulse given signal specifications: voltage range: 9V~30V, frequency range: 0kHz~100kHz.
5: MS instruction
When voltage source for MS instruction, to set up the F5 and FC group parameters, to determine the
corresponding relation of given signal and given voltage.
6: Simple PLC
When voltage source for simple PLC, you need to set up the FC group parameters to determine given
output voltage.
7: PID
According to the PID closed-loop produce output voltage. Specific content see introduce of FA group.
8: Communication given
Refers to the voltage by the HC is given by way of communication.
When above voltage source to select 1~8, 0%~100% are corresponding to the output voltage 0V~
rated motor voltage.

VF separation voltage rise time refers to the time needed for output voltage to be changed from the
0V to the rated motor voltage, the V/F separation voltage fall time refers to the time required for output
voltage to be changed from rated motor voltage to 0V. As show below diagram.
