Maximum Feedback Cable Lengths
Although motor feedback cables are available in standard lengths up
to 90 m (295.3 ft), the drive/motor/feedback combination may limit
the maximum cable length, as shown in the tables below. These tables
assume the use of cables recommended in the Motion Control
Selection Guide (publication GMC-SG001x-EN-P).
The maximum cable lengths for Ultra3000 drives with MP-Series (low
inertia and integrated gear) motors are given in the table below.
1
Refers to MPL-A/BxxxxS/M (single-turn or multi-turn) low inertia motors with absolute high-resolution feedback.
2
Refers to MPL-A/BxxxxH low inertia motors with 2000-line incremental feedback.
3
Refers to MPG-A/BxxxxS/M (single-turn or multi-turn) integrated gear motors with absolute high-resolution
feedback.
The maximum cable lengths for Ultra3000 drives with MP-Series food
grade motors are given in the table below.
1
Refers to MPF-A/BxxxxS/M (single-turn or multi-turn) food grade motors with absolute high-resolution feedback.
The maximum cable lengths for Ultra3000 drives with 1326AB (M2L/
S2L) and F-, H-, N-, and Y-Series motors are given in the table below.
1
Refers to 1326AB-Bxxxx-M2L/S2L (single-turn or multi-turn) motors with absolute high-resolution feedback.
2
Refers to F-, H-, N-, or Y-Series motors with incremental (optical encoder) feedback.
