If the screen doesn't display when you power on the Estun Control Systems, it could be due to a few reasons. First, check the power supply wiring to ensure it matches the nameplate. Rewire if necessary. It's also possible that the source voltage is too low or the connector isn't properly connected.
Why do I lose control of the Estun E21S?
Loss of control in Estun Control Systems can occur if the encoder cable is not properly connected. Also, verify that the motor direction wiring (X+, X-, A+, A-, G+, G-) is correctly configured.
What to do if the Estun E21S motor doesn’t run when operating?
If the motor doesn't run during operation, check if the machine is impeded or if the slider is back to TDC (Top Dead Center). Also, verify that the motor wire is well connected.
Why is the actual position of the X-axis unchanged or unshown on Estun Control Systems?
If the actual position of the X-axis remains unchanged or isn't displayed, check that the encoder cable is properly connected.
What to do if the back gauge motor doesn’t run when the X-axis is operated on Estun E21S Control Systems?
If the back gauge motor doesn’t run when the X-axis is operated, but the slider motor does, the wires of these two motors might be reversed. Rewire them accordingly.
Why can’t the Estun E21S Control Systems motor mutually convert from high to low?
If the motor can’t switch between high and low speeds, check if the signal is in effect and if the frequency converter is working normally. Also, confirm that the parameter Mute Dis. is programmed correctly.
How to fix the issue when the step can’t be changed in Multi-Step mode on Estun E21S Control Systems?
To resolve issues with changing steps in Multi-Step mode, verify that the STEP terminal is connected to +24V when the slider is on TDC (Top Dead Center).
What to do if the counter doesn’t work in Multi-Step mode on Estun E21S Control Systems?
If the counter isn't working in Multi-Step mode, check that the STEP terminal is connected to +24V when the slider is on TDC (Top Dead Center).
What to do if Estun Control Systems loses control during programming?
If the Estun Control Systems device loses control during programming, check whether the encoder cable is properly connected and ensure the motor-direction wiring is correct (X+, X-, A+, A-, G+, G-).
What to do if the motor of Estun Control Systems does not move when the program is running?
If the motor does not move when the program is running, check whether the mechanical part has been locked or the slider returns to the upper dead center. Also, verify that the motor wiring is well connected.
