Geo MACRO Drive User Manual
24 Connections
4. Motor cable shields should be bonded to the back panel using 360-degree clamps at the point they
enter or exit the panel.
5. Motor shields are best grounded at both ends of the cable. Again, connectors using 360-degree shield
clamps are superior to connector designs transporting the shield through a single pin. Always use
metal shells.
6. Running motor armature cables with any other cable in a tray or conduit should be avoided. These
cables can radiate high frequency noise and couple into other circuits.
Wiring 24 V Logic Control, J4
An external 24VDC power supply is required to power the logic portion of the Geo drive. This power can
remain on, regardless of the main AC input power, allowing the signal electronics to be active while the
main motor power control is inactive. The 24V is wired into connector J4. The polarity of this
connection is extremely important. Carefully follow the instructions in the wiring diagram. This
connection can be made using 16 AWG wire directly from a protected power supply. In situations where
the power supply is shared with other devices, it may be desirable to insert a filter in this connection.
The power supply providing this 24V must be capable of providing an instantaneous current of at least
1.5A to be able to start the DC-to-DC converter in the Geo drive. In the case where multiple drives are
driven from the same 24V supply, it is recommended that each drive be wired back to the power supply
terminals independently. It is also recommended that the power supply be sized to handle the
instantaneous inrush current required to start up the DC-to-DC converter in the Geo drive.

Wiring the Motors
The cable wiring must be shielded and have a separate conductor connecting the motor frame back to the
drive amplifier. The cables are available in cable kits (CABKITxx) from Delta Tau. (See Appendix A.)
Motor phases are conversed in one of three conventions. Motor manufacturers will call the motor phases
A, B, or C. Other motor manufacturers call them U, V, W. Induction motor manufacturers may call them
L1, L2, and L3. The drive’s inputs are called U, V, and W. Wire U, A, or L1 to the drive’s U terminal.
Wire V, B, or L2 to the drive’s V terminal. Wire W, C, or L3 to the drive’s W terminal.
The motor’s frame drain wire and the motor cable shield must be tied together at the mounting stud (5mm
thread) on top of the Geo drive product.
