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 recommended cables as shown in the Motion
Control Selection Guide (publication GMC-SG001x-EN-P).
The maximum cable lengths for 1394 system/axis modules with MP-
Series (460V) and 1326AB/AS motors are given in the table below.
1
Refers to MPL-BxxxxS/M (single-turn or multi-turn) low inertia motors with absolute high-resolution feedback.
2
Refers to MPL-BxxxxR low inertia motors with 2-pole resolver feedback.
3
Refers to 1326AB-Bxxxx-M2L/S2L (single-turn or multi-turn) motors with absolute high-resolution feedback.
4
Refers to 1326AB/AS-Bxxxx-21 motors with resolver feedback.
