Chapter One: General
1.1 Overview
The Glentek Inc. SMB9675-1A-1-7700 spindle drive uses flux vector technology to close a torque
(current) feedback loop. When applied to a three phase induction motor, the result is servo motor like
performance from a standard three phase induction motor. The Digital Signal Processor (DSP) based
spindle drive uses its high speed math processing capability to continuously calculate flux and torque
vectors and to maintain a constant 90 degree phase difference between the vectors. This technique
allows torque control from zero speed to base speed and above. Encoder feedback provides the
shaft position data needed to calculate the vectors and velocity data, thus, Vector Control allows
precise speed control down to and including zero speed of an induction motor.
The SMB9675-1A-1-7700 spindle drive can operate in sensor-less mode (no feedback is needed).
This mode of operation is usually referred to as inverter mode or VFD (Variable Frequency Drive)
mode. With advanced mathematic algorithms and latest DSP technology, the Glentek SMB9675-1A-
1-7700 is optimized to produce a steady starting torque from standstill right up to full speed with high
efficiency. The applied frequency and voltage are increased at a controlled rate and ramped up to
accelerate the load without drawing excessive current.
1.2 Intended Application
The SMB9675-1A-1-7700 is intended as a drop-in replacement spindle drive for FADAL

Note: Positions C, D, E, and F are reserved for future configurations.
Note: Align the dial to the desired configuration before installation or disable the drive with an M5
(spindle stop) command BEFORE rotating the dial. The four place seven-segment displays will
display the operation mode selected (i.e. 7700, 7701, etc.) for seven seconds, then reverts to
displaying motor rpm. Enable the drive to run in the new mode.

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)

Chapter Three: Initialization and Power Up
3.1 Before Any Initialization
The only setup required by the end user is to select the mode of operation. All the tuning has been
preset at the factory, meaning the drive will run correctly. If applying minor changes (adjusting input
command offsets, etc.) to the spindle drive, use the procedures below for reference.
3.2 Turning the Power On
Carefully recheck the wiring. Restore power to the VMC. For seven seconds the four rightmost seven-
segment displays will show the spindle drive configuration. Afterwards, those four displays will show
the rpm value of the spindle motor, not the spindle itself. Confirm the desired mode of operation has
been selected.
3.4 Operating the Spindle
From the VMC control panel operate the spindle and confirm the spindle runs at the commanded
speeds and in the correct direction (CW and CCW). It is important to note, the 4 digit display on the
drive reports the speed of the spindle motor, the speed of the spindle itself may be different
depending on the machine design and mode. The drive calculates the rpm from the encoder signals
when operating in vector mode, when the drive is used in VFD or inverter mode (no encoder) the rpm
is calculated from the input command signal voltage received from the Fadal control.
3.5 Pot Adjustments
Normally, no adjustments are needed. However, for convenience, there are two pots (see page 26)

CCW directions. The signal gain pot can be used to make small adjustments to the speed of the
spindle. The pots are not intended to correct large differences between commanded speed and actual
speed. If after initial installation the expected speeds are significantly different from the commanded
speeds double check that themode of operation from the table is correct for the VMC. Consult your
distributor or Glentek technical support for additional help.

Attach the black lead to TP7 (see page 26) and the red lead to TP3 for balance and to TP4 for signal
gain. Adjust the voltage to 1.50VDC.
3.6 Rigid Tap Test (Optional)
If desired you can test the rigid tap mode of your VMC by performing the following procedure. This
procedure is drawn from the FADAL maintenance manual. Install the test screw (SVT-0077). The
