Chapter 4 Explanation of Functions

4.3 Functions Available When the Feedback Option Board (SJ-FB) Is Mounted

4.3.1 Functions requiring the SJ-FB

- The feedback option board (SJ-FB) is generally required in the following cases:

<1> When "05" (V2: vector control with sensor) is specified for V/F characteristic curve selection, 1st motor(A044)

<2> When pulse train frequency input is specified by one of the following methods:

-"06" (pulse train input) is specified for the run command source setting (A001).

-"10" (operation function result) is specified for the run command source setting (A001), and "05" (pulse train frequency) is specified for operation-target frequency selection 1 (A141) or operation-target frequency selection 2 (A142).

-"03" (pulse train frequency input) is specified for the PV source setting (A076).

-For the wiring and DIP switch setting of the SJ-FB, refer to the instruction manual for the SJ-FB.

-You can check the direction of motor rotation with the actual-frequency monitoring function (d008). For checking with this monitoring function, specify "00" (VC) for the V/F characteristic curve selection (A044) and make the inverter operate the motor. (Normally, a positive frequency is monitored when a forward-operation command is input, and vice versa.)

4.3.2 V2 control pulse setting

To use the V2 control pulse setting function, specify "00" (ASR: speed control mode)

or "01" (APR: pulse train position control mode) for the control pulse setting (P012). In speed control mode, select a device to input frequency commands by the frequency source setting (A001).

In pulse train position control mode, each frequency command is generated from a position command pulse train and the feedback

of the position data detected by the encoder. The position command is input via an intelligent input terminal, to which the input of the pulse train position command is assigned. You can perform the position control with the command.

Select one of three input formats for the pulse train position command by the pulse train mode setting (P013).

To use the pulse train position control mode, assign function "48" (STAT) to an intelligent input terminal. The inverter accepts a pulse train position command only when the STAT terminal is on.

You can clear the position deviation data by an external signal. Assign function "47" (PCLR) to an intelligent input terminal. Turning the PCLR on and off clears the position deviation data in the inverter.

To output a speed deviation error signal, assign function "22" (DSE) to an intelligent input terminal, and specify a deviation level as the speed deviation error detection level (P027). If the deviation of the actual frequency (motor speed) from that specified by the frequency command exceeds the error detection level (P027), the inverter will output the DSE signal.
