The User Manual of 580 Series General Frequency Converter

4.9.3 Setting and switching of multi-motor parameters

The frequency converter supports switching four motor parameter sets. The parameters of Motor 1, parameters of coding disc and others constitute Groups F1 and F2; Motor 2, Motor 3 and Motor 4 correspond to the parameter set of Function Code A2, A3 and A4. Select current valid motor parameter set through designation by Function Code F0-24 or through Function 41, 42 of digital input terminal. However, when Function 41, 42 of digital input terminal is valid, the priority will be available and F0-24 setting will be invalid in this case.

4.10 The usage of DI port of frequency converter

The control panel is set with 7 DI ports which are numbered as DI1 ~DI7. If I/O expansion card is added, 3 additional DI ports shall be increased. DI ports on the expansion card will be numbered as DI8 ~DI10 at this moment.

The internal hardware of DI port is equipped with 24Vdc power supply for testing. The user shall only keep DI port in short circuit with COM port so as to input DI signal to the frequency converter.

In case of F4-38=0000 and F4-39=0000 in the default value, the signal is valid (Logic 1) when DI port is short-circuited; when DI port is suspended in the air, DI will be invalid (Logic 0) signal;

The user can change the valid mode of DI port, which means that the signal is invalid (Logic 0) when DI port is short-circuited; when DI port is suspended in the air, Di will be valid (Logic 1) signal. At this moment, the corresponding place to F4-38 or to F4-39 shall be changed to 1 and these two function codes correspond to valid mode setting of DI1~DI5 and DI6 ~DI10.

The frequency converter is also set with software filter time (F4-10) for input signal of DI port to improve anti-interference level.

For DI1 ~DI3 input port, the port signal delay function is particularly provided to help some applications beyond delayed processing:

The functions of 10 DI ports above can be defined in function codes F4-00~F4-09 and each DI can be determined among 50 functions. See the detailed description of function codes F4-00 ~F4-09.

For the design of hardware characteristics, only DI5 can accept high-frequency pulse signal. If high-speed pulse counting is required, please arrange it at DI5 port.

4.11 The usage of DO port of frequency converter

The control panel is set with 3-way DO output, including FM, DO1, TA/TB/TC. Therein, FM and DO1 are transistor type output and can drive 24Vdc low-voltage signal loop; TA/TB/TC is relay output and can drive 250Vac control loop.

2-way output, including DO2 and PA/PB/PC, can be expanded by connection to external expansion card. Therein, DO2 is transistor output and PA/PB/PC is relay output.

The value of function parameters F5-01~F5-05 as set can be used to define the functions of all DO outputs and indicate the working conditions and various alarms of the frequency converter, and there are about 40 functions set in total to help the user meet specific automatic control requirements. Please see the detailed description of function parameters in Group F5 for the specific set value.

Port name	Corresponding function code	Description of output characteristics
FM-CME	When F5-00=0, F5-06	Transistor, used to output high-speed pulse of 10Hz ~100KHz; driving capacity: 24Vdc, 50mA
	When F5-00=1, F5-01	Transistor; driving capacity: 24Vdc, 50mA
TA-TB-TC	F5-02	Relay; driving capacity: 250Vac, 3A
PA-PB-PC	F5-03	Expansion card and relay; driving capacity: 250Vac, 3A
DO1-CME	F5-04	Transistor; driving capacity: 24Vdc, 50mA
DO2-CME	F5-05	Expansion card, transistor; driving capacity: 24Vdc, 50mA

In case of F5-00=0, FM port is in high-speed pulse output mode. The internal operating parameter shall be indicated by output pulse frequency and the output pulse frequency will get increased with the increasing read. The reading of100% corresponds to 100KHz. The attributes of internal parameters shall be defined by Function Code F5-06.

4.12 Characteristics and preprocessing of AI input signal

The frequency converter totally supports 3 ways of AI resource. Therein, AI1 and AI2 are provided by the control panel and it is required to connecting expansion card for AI3.

Port	The characteristics of input signal
AI1-GND	The signal of 0 ~10Vdc can be accepted
AI2-GND	Jumper J8 at “V” home position can accept the signal of 0~10Vdc; Jumper J8 at “I” home position can accept current signal of 4~20mA
AI3-GND	If this port is provided by the expansion board, the signal of -10 ~10Vdc can be accepted

When the frequency converter uses external voltage/current signal, AI shall be used if frequency source, torque, voltage in VF separation, PID or feedback is given. The actual reference or feedback physical quantity relation corresponding to voltage or current value shall be set by means of F4-13~F4-27.

Fig. 4-30 The actual reference corresponding to AI signal

The sampling value at AI port can be read among function codes U0-09~U0-11; the converted value will be used for internal subsequent calculation so that the user cannot read it directly.

4.13 The usage of AO port of frequency converter

The frequency converter totally supports 2-way AO output. Therein, AO1 is provided by the control panel and IO expansion card must be connected for AO2.

Port	The characteristics of input signal
AO1-GND	The signal of 0~10Vdc can be output at “V” home position with J5 in short circuit
	The current signal of 0~20mA can be output at “I” home position with J5 in short circuit
AO2-GND	This port is provided by the expansion board and can output the signal of 0~10Vdc

AO1 and AO2 can be used as analog mode to indicate internal operating parameters and the parameter attribute can be selected through function codes F5-07 and F5-08.

The specified operating parameter may be changed before output and the change characteristic curve is shown as the diagonal in the following figure, Y＝kX＋b where X is operating parameter to be output, and k and b of AO1 can be set by function codes F5-10 and F5-11.

4.14 The usage of PG port of frequency converter

If the closed-loop vector control (F0-01=1) of sensor is used to improve frequency conversion performance, the encoder shall be mounted on the motor shaft and the signal of encoder will be reported to the frequency converter by PG card (signal interface card of the encoder). 580 series frequency converter is set with total 2 kinds of PG cards with different signal characteristics for the user.

The frequency converter supports 3 kinds of encoders including differential encoder, rotary transformer and open collector encoder.

According to encoder type in service, it is required to set the relevant parameters of different encoders and the motor parameter set 1 is taken for illustration as follows:

For a differential encoder, F1-27 is used to set encoder lines and F1-28 is set to 0: ABZ incremental encoder

For an open collector encoder, F1-27 is used to set encoder lines and F1-28 is set to 0: ABZ incremental encoder

For a rotary transformer, F1-28 is set to 2: rotary transformer

For the specific usage of the encoder, please see the appendixes in this manual: The usage of expansion card for general encoder

4.15 The usage of serial communication of frequency converter

When RS485 communication is used, see the functions of Group Fd for hardware communication parameters of communication port. The normal communication needs the precondition that communication rate and data format conform to the upper computer.

The communication protocol for MODBUS-RTU slave station is built in the serial port of 580 so that the upper computer can inquire or change the function codes of frequency converter, running state parameters, run command transmitted to the frequency converter, operation frequency and others through serial port.

Fig. 4-31 The usage of serial communication of frequency converter

In 580 frequency converter, the function code, running state parameters, running instructions and information are organized in the mode of “register parameter address” and the upper computer can communicate with the frequency converter effectively according to “register parameter address”.
