Parameter Description VD500 Series Inverter User Manual
- 98 -
Pulse can only be given from multi-function input terminal HDI1 input.
HDI1 terminal input pulse frequency and the corresponding set of relations, through the F5-37~F5-40
setting, the corresponding relations of 2 points of straight line, the corresponding set of input pulses
100.0%, is refers to the relative maximum frequency F0-10 percentage.
6: MS reference
Select MS reference operation mode, need through the digital quantity input DI terminal state of
different combination, corresponding to different set frequency values. VD500 can set up more than 4
MS reference terminal, the 16 kinds of sate of 4 terminals by FC group function code corresponding
to the arbitrary 16 “MS reference”, “MS reference” is relatively maximum frequency F0-10 percentage.
When DI digital quantity input terminals as MS reference terminal function, need to do accordingly
setting in the F5 group, specific content please refer to the related function parameters of F5 group.
7: Simple PLC
When frequency source is simple PLC, the operation frequency source of inverter can be in 1~16
arbitrary frequency switching between operation instruction, holding time 1~16 frequency instructions,
their respective deceleration time can also be user settings, specific content reference FC group of
related instructions.
8: PID
The selection process of PID control output as the running frequency. Commonly used in the scene of
the closed loop technology, such as constant pressure closed loop control, constant tension
closed-loop, etc.
Application of PID as frequency source, you need to set up FA group (PID function parameter group)
related parameters.
9: Communication setting
Refers to the main frequency source by the HC is given by way of communication.
VD500 supports three kinds of communication mode: Modbus, Profibus-DP, CANopen, the three
kinds of communication can’t be used at the same time.
Modbus communication is standard, the other two kinds of communication card is optional, the user
to select according to need, and need to set the parameters F0-23 (communication extension card
type) correctly.
10: Keypad potentiometer
Frequency source is given by keypad potentiometer.

Auxiliary frequency source as a separate frequency given channel (that is, the switching frequency
source selection for A to B), its usage same as the main frequency source A, the method of use can
reference the related description of F0-02.
When auxiliary frequency source used as superposition of given (i.e. frequency source selection for
A+B, A to A+B switch or B to A+B switch), need to pay attention to:
1)
When the auxiliary frequency source for digital given, preset frequency (F0-09) doesn’t work,
the user through the keyboard ▲,▼ key (or the UP/DOWN of multi-function input terminal) for
the adjustment of the frequency.
2)
When the auxiliary frequency source for analog input given (AI1, AI2) or pulse input given, input
100% of the set corresponding auxiliary frequency source range, can be set through by the
F0-06 and F0-07.
3)
When frequency source for pulse input given, is similar to analog given.
