The Y axis of my BRM Pro is not working.
Please follow these steps if the Y-axis of your BRM Pro laser machine does not work
Check if the rotation unit is plugged into the connector. If the rotation unit is plugged in, you will not be able to use the Y-axis. Unplug the rotation unit to be able to use the Y-axis.
If the rotation unit is not plugged into the laser machine you can check if all doors are closed. All of them must be closed before the axes can move.
Next, press the emergency stop. After pressing the emergency stop, you can rotate it a quarter turn, clockwise. The button will come up now. Press the reset-button. You will also see that the signal lamp changed from red to green. Press the reset button.
After completing these steps and there is still no movement, you can check whether you can move the Y-axis manually. If it is difficult or impossible to move, it is under tension. If the Y-axis can be moved easily, there is no tension on it.
If there is no tension on the Y-axis, get the rotation unit, provided you have one. Connect the rotation with the plug. The socket for the plug is on the right-hand side of the machine. After connecting the rotation, remove the plug from the socket to disconnect the rotation. The time between connecting and removing the plug does not need to be long.
Listen for a click coming from the electrical cabinet when connecting the plug and removing it. If you don’t hear a click, you can open the door of the electrical cabinet. Make sure you don’t touch anything, as this can cause dangerous situations.
Checking the relays
There are several relays in the electrical cabinet. When the rotation is connected, relay 100KA1 should switch. Check this by looking at this relay. Usually, a light on the relay will turn on or off when it switches. A relay is a square block, often transparent. There are several relays next to each other, on the left-hand side of the electrical cabinet.
When the relays switch when you insert and remove the plug, you will also usually see that one of the drivers switches off and another driver switches on. The driver for the U-axis will switch on when you connect the rotation and the driver for the Y-axis will switch off at that moment. And vice versa. The drivers are blue and black and about 10 cm wide. They are on the right-hand side of the electrical cabinet. They often have stickers on them, look for the U-axis and the Y-axis driver.
Should all this work fine but the problem persists, it is best to submit a ticket describing the steps you have already taken.
In case you don’t have a rotation unit or if the axis is powered and you have these problems, you can open the electrical cabinet. Make sure you don’t touch anything, as this can cause dangerous situations. Verify that the red light on the driver is flashing. If it is blinking then it is important to count how many times the light blinks. This may be 4 or 7 times.
Send in a ticket mentioning the steps you have already taken and how often the red light is blinking.
