Just initialize the parameters first and then debug.
Debugging method of grouting machine motor controller: initialize parameters before wiring. On the controller: Select the control mode, clear the PID parameters, so that the enable signal is turned off by default when the controller is powered on, and save this state to ensure that it will be in this state when the controller is powered on again. Then connect the wiring, power off the controller, connect the signal line between the controller and the servo, and finally debug the direction.
The grouting machine injects the prepared slurry into the space that needs to be filled and reinforced to achieve the purpose of filling the gaps to stabilize the surrounding rock or block the water flow channel.
