Other Supplier’s Motors
If you want to use a motor other than those recommended here, it must be a three phase mo-
tor with 120° commutation timing. The motor must also have an incremental encoder (index
signal is not required) with no fewer than 50 lines and no greater than 32,000 lines. The halls
andencodermustoperatefrom+5VDC,200mAmax(suppliedbytheBLUdrive).Thehall
signals may be single-ended or differential. We strongly recommend that the encoder have
differential line driver outputs, but single-ended may be acceptable if you use a shielded
cable.
The BLU servo drives feature sine commutation, which makes motors run more smoothly
than trapezoidal drives. If you choose a low cost motor with internal hall effect devices in-
stead of a quality motor with precision commutation tracks on the encoder disk, your perfor-
mance may suffer.
If using other motors than AMP’s you will need a ferrite bead on each motor lead, with the
wire wrapped several turns - please refer to the section on wiring ferrites, page 17, or call an
Applied Motion Products service representitive.
