Maximum Axis Speeds
Axis feedback resolution (for 1326AB motors with high–resolution
feedback devices) for multiturn (SinCos) absolute high–resolution
feedback devices is selected in AMP. The axis feedback resolution is
1,048,576 counts/rev. The maximum motor RPM for both devices is based
on the maximum speed on the 1326AB motor plate found on the side of
your motor’s housing. Actual final axis speed is based on gearing and lead
screw pitch.
The 1326AB motors are equipped with devices used to generate velocity
feedback and provide motor commutation. These devices can also be used
as positioning devices for the axis.
The high–resolution feedback device’s feedback is wired directly from the
motor–mounted high–resolution feedback device to the 9/440HR Feedback
board found in the system module. This cable can be purchased directly
from Allen-Bradley (cat. no. 1326-CECU–x).
