Mounting and Wiring Two
Identical Coils in Tandem This type of installation requires a custom motor-database file, which is available
upon request. Contact Application Engineering at 631.344.6600 to request this
file.
These tables and figures show the wiring and spacing for two identical coils
mechanically top mounted to the same plate and driven by one amplifier. There
are three configurations shown here for mounting motors in tandem: power and
encoder cables exiting on the right, the center, and on opposite ends.
Cables Exit to the Right
If mounting coils in tandem, such that the power cables exit both the coils on
right side, as shown, use the following table to find the mounting distance and the
phase wiring.

Coils must have identical part numbers. Using mismatched coils
will cause a hazardous condition resulting in damage to the
equipment and a possible fire.
