Read P1-02 Upper computer sending command: 0103 01 02 00 02 CRCL CRCH Driver returning command: 01 03 04 00 12 D6 87 CRCL CRCH Parameter functions: It is used for address mapping upon Modbus communication, and totally 10 groups of 16-bit parameters can be mapped (5 groups of 32-bit parameters). Two examples are given below for demonstration. Example 1 : P7-30 = 7654H, P7-31 = 2000H (d0-00 communication address). When the address received by the driver is the original address (7654H), it will be processed by the program as a target address (2000H), i.e. actually the operation is made to the d0-00 function code. Example 2 :
P7-32 = 7655H, P7-33 = 8906H (P9-06 communication address 1 + 8000H); P7-34 = 7656H, P7-34 = 8907H (P9-06 communication address 2 + 8000H). When the upper computer operates two consecutive addresses with 7655H as the starting address, it is equivalent to an operation to P9-06; in case of a write operation, data will not be saved to EEPROM in default. Example 3 : Based on settings in examples 1 and 2, the upper computer can realize read/write operations to non-consecutive addresses by using 1 command (mapping of the initial address is required). Namely, when the upper computer reads 3 addresses starting from 7654H, the driver will return values of parameters d0-00 (16-bit) and P9-06 (32-bit).
8.13 P8-xx Expanded function parameters Parameter functions: Set the motor speed and acceleration/deceleration time upon jog; the reference acceleration/deceleration time is the time required for the motor to accelerate from speed 0 to the rated speed or to decelerate from the rated speed to speed 0. Jog of the driver can be realized through the function parameter AF-02 or through the DI terminal set to JOG-P or JOG-N. Jog operation through the function parameter AF-02 is available only when the servo is OFF, while jog operation through the DI terminal is available whether the servo is OFF or ON. Execution of the jog command:

The target address requires corresponding actual parameter; otherwise an error may occur upon communication; 2. Address mapping of a 32-bit parameter requires space of two consecutive groups; 3.
When 0x03/0x10 reads/writes n consecutive addresses, if the starting address has been mapped, then the remaining (n-1) addresses also require mapping, and target addresses of mapping can be non-consecutive.
