Troubleshoot Power or Wiring for Angle Motors and VFDs

Before You Begin

Safety: Stop the machine, follow the site lockout/tagout procedure, verify that hazardous energy is controlled, and release or secure stored mechanical and pneumatic energy before opening a panel, removing a guard, or adjusting components. Electrical work must be performed by a qualified technician.

Power for each movement that the saw makes will follow this general path.

1. VFD (in)
2. VFD (out)
3. Terminal Block in # (Example 46)
4. Terminal Block out # (Example 46) (the number will be the same as “in”)
5. Motor

VFD in wires are the two or three wires on the left labeled “R/L1”, “S/L2”, “T/L3”

VFD Out wires are the three wires on the right side labeled “U/T1”, “V/T2”, “W/T3”

From there power goes to terminal blocks that are either on the middle left or middle right side of the panel (the image below is of the right side).

The power/GND wires from the VFD come in on the right side of the terminal block (in this example) pass through, then go out to the motors on the left side.

From the terminal block, the wires go directly to the motor

To access the motor wires, remove the four screws holding the cover in place.

Confirm the Result

After restoring the machine through the approved startup procedure, confirm that the position or count changes in the correct direction, returns consistently, and reaches the commanded value without an encoder, calibration, or overrun warning.

If the issue remains, record the exact on-screen message, affected component, indicator-light state, and the last change made. Provide those details to Enventek Technical Support; do not repeatedly recalibrate or replace parts without identifying the cause.
