Troubleshooting Steps for JUGAO E21 Hydraulic Press Brake

A frequent issue encountered when operating the JUGAO E21 controller-equipped hydraulic press brake is that the machine’s ram fails to lower, even after the equipment is powered on and the foot switch is activated. We’ll detail the exact fix for this problem here.

First, check the display interface of the E21 controller: you’ll notice that the actual values of the X and Y axes do not match their set target values (XP and YP respectively). The solution is straightforward—adjust the numerical values of the X and Y axes to align with the preset XP and YP values. Once this setting is completed, press the machine’s start button and step on the foot switch as usual, and the ram will lower and operate in the normal manner.
