Page 169: Home Search Function
4.3.11 Home search function The home search function allows you to make the inverter locate the motor shaft at a specified position. You can use this function, for example, to stop a metal-cutting machine to replace the tool attached to the main spindle. When using the home search function, be sure to insert a reference point pulse signal between the EZP pulse and EZN pulse signals from the encoder.
Page 170 Note 1: Since the inverter positions the motor shaft within two turns while decelerating the motor, do not specify a high frequency as the home search speed. Otherwise, the inverter may trip during home search because of the overvoltage protection function. Note 2: For setting the home search stop position, the periphery of the motor shaft is divided into 4,096 sections to determine points No.

Page 174: Multistage Position Switching Function (Cp1/Cp2/Cp3)
4.3.14 Multistage position switching function (CP1/CP2/CP3) - When functions "66" (CP1) to "68" (CP3) are assigned to terminal [1] function (C001) to terminal [8] function (C008), you can select a position setting from multistage positions 0 to 7. - Use multistage position settings 0 to 7 (P060 to P067) for the position settings. If no position settings are assigned to terminals, multistage position setting 0 (P060) is assumed.
Page 175: Zero-Return Function
4.3.16 Zero-return function (ORG, ORL) - One of three types of zero-return operations can be selected by zero-return mode selection (P068). When a zero-return operation ends, the current position counter is cleared (to 0). - Use zero-return direction selection (P069) to select the direction of zero-return operation. - If zero-return operation is not performed, position control is performed based on the assumption that the motor position detected at power-on is the origin.
Page 176: Forward/Reverse Drive Stop Function (Fot/Rot)
Note: In the case above, make sure that the power supply to the power terminals (R, S, and T) of the inverter power circuit or inverter output (U, V, and W) is disconnected from the motor. Performing teaching operation with the power supply and inverter output connected may result in personal injury or damage to equipment.
Page 177: Servo-On Function
4.3.20 Servo-on function The servo-on function allows you to set the inverter in a speed- servo locking state with a signal input via an input terminal during operation. This function is effective when "05" (vector control with sensor) is specified as the V/F characteristic curve selection (A044).
Page 178: Pulse Train Frequency Input
4.3.21 Pulse train frequency input The pulse train frequency input function allows you to use the pulse train input via the SAP or SAN terminal as a frequency command or PID feedback data in each control mode. (You can use this function in every control mode.) Specify the input frequency corresponding to the allowable maximum frequency as the pulse train frequency scale (P055).
Page 179: Communication Functions
4.4 Communication Functions The inverter can engage in RS485 communications with an external control system that is connected to the TM2 terminal block (on the control circuit terminal block board) of the inverter. The SJ700 series inverter shares the ASCII communication protocol with the SJ300 and L300P series inverters.
Page 180 Connection As illustrated below, connect the inverters in parallel to the external control system, and connect the RP and SN terminals with a jumper on the inverter at the end of the network. (Similarly jumper the RP and SN terminals when only one inverter is connected to the external control system for RS485 communication.) Connecting the RP and SN terminals enables the terminating resistor in the control circuit terminal block board of the inverter, which suppresses signal reflections.
Page 181 (3) Communication test mode Use the communication test mode to check the hardware of the RS485 communication train. (Procedure for communication test) 1) Remove all cables from the TM2 terminal block to perform a loopback test. 2) Make the following setting with the digital operator of the inverter: - Specify "02"...
Page 182: Communication In Ascii Mode
4.4.1 Communication in ASCII mode (1) Communication protocol The communication between the inverter and external control system is based on the following protocol: External control system Inverter (1): Frame that is sent from the external control system to the inverter (2): Frame that is sent from the inverter to the external control system The inverter sends frame (2) as a response always after receiving frame (1).
Page 183 The commands are described below. (i) 00 command: This command instructs the inverter to drive the motor (for forward or reverse rotation) or stop the motor. (To use this command, set "A002" to "03" [RS485].) - Transmission frame Frame format Station No.

Page 196 The formats of the query and response frames are described below. Message configuration: Query (i) Slave address The slave address is a number 1 to 32 that is assigned to the inverter (slave) beforehand. (A query is received by the inverter having the same slave address as that specified in the query.) The query with the slave address set to "0"...
Page 197 (iv) Error check code The Modbus-RTU protocol uses the cyclic redundancy check (CRC) as the error check method. The CRC code is the 16-bit data generated for a data block that has an arbitrary data length (in units of 8 bits). A generative polynomial for CRC-16 (X Example of CRC-16 calculation operation...
Page 198 Message configuration: Response (i) Time required for communication After the inverter receives a query, the inverter waits for the sum of the silent interval (corresponding to the transmission of 3.5 characters) and the communication wait time (C078) before sending a response.
Page 199 (4) Explanation of function codes (i) Reading the coil status [01h] This function reads the coil status (on or off). (Example) When reading the status of the intelligent input terminals [1] to [6] of the inverter at slave address "8": Assume that the intelligent input terminals are in the status as shown below.
Page 200 (ii) Reading registers [03h] This function reads a specified number of registers beginning at a specified register address.

Page 203 (vii) Writing data to multiple registers [10h] This function writes data to sequential registers. (Example) When setting "3,000 Hz" as the Acceleration (1) time (F002) in the inverter at slave address "1": Since register "1103h" and "1104h" to store the Acceleration (1) time (F002) have a data resolution of 0.01 seconds, specify "300000"...
Page 204 (5) Enter command (storing the updates of register data) Neither the command (06h) to write data to a register nor the command (10h) to write data to multiple registers can store the updates they made in the internal memory of the inverter. Turning the inverter power off without storing the updates deletes them and restores the original register settings.

8.1 Precautions for Data Setting The default display mode limits the screens (parameters) that can be displayed on the monitor. To enable the display of all parameters, specify "00" (full display) for the function code display restriction (b037). To enable the parameters to be changed while the inverter is operating, specify "10" for the software lock mode selection (b031). 8.2 Monitoring Mode With the default settings, the monitor always displays the data output according to the output frequency monitoring (d001) after power-on.

Page 279 Upgrading from the SJ300 Series The SJ300 series inverter is upwardly compatible with the SJ700 series inverter. Therefore, you can: - mount the control circuit terminal block board of the SJ300 series in the SJ700 series without removing the connected cables, - copy the parameter settings from the SJ300 series into the SJ700 series, and - use the option boards mounted in the SJ300 series for the SJ700 series without removing the connected cables.
Page 280 Appendix (2) Copying the parameter settings If you use an optional remote operator (SRW-OJ or SRW-OEX), you can copy (import) the parameter settings from the SJ300 series into the SJ700 series. Note, however, that you cannot copy the parameter settings from the SJ700 series to the SJ300 series because the SJ700 series has many new functions and additional parameters.
