terminals).
When the AC drive is powered on again after power failure, the set frequency is the value memorized at the
moment of the last power failure.
Note that P0-23 (Retentive of digital setting frequency upon power failure) determines whether the set
frequency is memorized or cleared when the AC drive stops. It is related to stop rather than power failure.
2: VS
3: AS
4: VS2
The frequency is set by analog input. The HV580L control board provides two analog input terminals (VS, AS).
Another AI terminal (VS2) is provided by the I/O extension card.
VS is 0V

10V voltage input, AS can be 0V

20mA current input, it is
determined by jumper J8, VS2 is -10V

10V voltage input.
The HV580L provides five curves indicating the mapping relationship between the input voltages of VS, AS
and VS2 and the target frequency, three of which are linear (point - point) correspondence and two of which
are four-point correspondence curves. You can set the curves by using function codes P4-13 to P4-27 and
function codes in group A6, and select curves for VS~VS2 in P4-33. For the five curves specific corresponding
relations, please refer to the P4, A6 group function code.
5: Pulse setting (X5)
The frequency is set by X5 (high-speed pulse). The signal specification of pulse setting is 9
–30 V (voltage
range) and 0
–100 kHz (frequency range). Input pulse can only be given from multifunctional input terminals X5.
The relation between X5 terminal input pulse frequency and the corresponding set, is designed through the
P4-28, the corresponding relation of two points is straight line corresponding relation. The corresponding
value 100% of pulse setting corresponds to the value of P0-10 (Maximum frequency).
6: Multi-reference
In multi-reference mode, combinations of different DI terminal states correspond to different set frequencies.
The HV580L supports a maximum of 16 speeds implemented by 16 state combinations of four DI terminals
(allocated with functions 12 to 15) in Group PC. The multiple references indicate percentages of the value of
P0-10 (Maximum frequency).
If a X terminal is used for the multi-reference function, you need to perform related setting in group P4.
The HV580L supports four host computer communication protocols: Modbus, PROFIBUS-DP, CANopen and
CANlink. They cannot be used simultaneously.
If the communication mode is used, a communication card must be installed. The HV580L provides four
