Note: (1) In above example, modify the function of DI2 / DI3, and write the value as DI2=0x28 ( means path 0), DI2=0x29
(means path 1);
(2) The data type of parameter is 32bit, which include high 16bit register and low 16bit register, usually we use low 16bits only,
but it needs to take the high 16 bits as beginning when we read/write multiple parameters continuously.
4.3 Modbus & PR Parameters
4.3.1 Basic Parameters
Leadshine RS485 parameter data type is 32 bits, a parameter contains two registers of high 16 bits and low 16 bits, only the
lower 16 bits are used in practice. However, when reading or writing multiple parameters in succession, the high 16 bits of the
parameter need to be used as the start, usually 00.

Forced enable by software
Software forced enable has a higher priority than
IO enable, and when this value is 0, the enable
status of the drive only depends on the IO signal.
When this value is 1, the motor is enabled
regardless of the IO signal status.
