Chapter Two: Installing a Glentek Spindle Drive into a Fadal VMC
2.1
Removing the old drive
Turn off the power to the VMC and wait 5 minutes before beginning removal. Disconnect all the
wires and cables. If any wires are not labeled take note of their location. Of the cables, only the
Control cable and the Delta/Wye cable can be confused, both are 6 terminal connectors. The control
cable has 6 sockets in the connector and Delta/Wye cable has 3 sockets in the connector. Unbolt the
old drive and remove.
2.2
Mechanical Installation
Install the new drive (slots down) by first resting the drive on the lower mounting studs in the panel
and positioning the drive over the studs at the top. Hold the drive against the panel and loosely
install four screws, top two first. Then tighten all four screws.
2.3
Electrical Installation
2.3.1 Power Terminal Block Connections
Begin the wiring by connecting the AC, regenerative braking, motor, and green ground wires.
Match the wire labels to the terminal block labels. Check connections for tightness. See Appendix A
for more details.
2.3.2 Load Meter Cable
Connect the load meter cable by connecting the black wire to P1-1 screw terminal and the red wire
to P1-2.
2.3.3 Spindle Control Cable
Connect the spindle control cable to P2. The spindle control cable has 6 sockets installed; do not
mistake the wye/delta connector with only 3 sockets.
2.3.4 Wye/Delta Cable
Connect the wye/delta cable to P4 (wye/delta is an option for 7500 RPM spindles; your VMC may not
have this cable).
2.3.5 Encoder Feedback Cable
Connect the encoder feedback from the motor (9 terminal connector) to P3 (VFD drives doe not
need this cable).
2.3.6 Rigid Tap Cable (Encoder Output To CNC Control)
For VMC’s with the Rigid Tap option, connect the rigid tap cable from the CNC to P5 of the spindle
drive. Use the installation drawing (Drawings & Diagrams) to match the wires by color to the correct
terminal.
