Parameter description
2: Three-wire control mode 1: This mode is enabled terminal DI3, respectively, by direction DI1, DI2
control.
When there is the need to run, the terminal must first DI 3 closed by the rising edges of the DI1 or DI2 to achieve
forward or reverse motor control.
When you need to stop, by disconnecting DI3 terminal shall signal to achieve. Wherein, DI1, DI2, DI3 are
multifunctional input terminals of DI1 ~ DI10, DI1, DI2 pulse are effective, DI3 is effective level.
Among：
SB1: stop button
3: Three-line control mode 2: This mode enable terminal to DI 3, run the command given by the DI1,
DI2 direction by the state to decide.
Terminal function is set as follows：
In the need to run, must first close the DI3 terminal, from the DI1 of the pulse rise along the
motor running signal, DI2 state of the motor direction signal.
In the need to stop, it is required to disconnect the DI3 terminal signal to achieve. Among them,
DI1, DI2, DI3 for the DI1 ~ DI10 multi function input terminals, DI1 for the pulse effective, DI3, DI2
is effective.
