Maximum Axis Speeds
Axis feedback resolution (for 1326AB motors with high--resolution
feedback devices) for single (SinCoder) and multiturn (SinCos) absolute
high--resolution feedback devices is selected in AMP. The axis feedback
resolution is 2,097,152 counts/rev or 1,048,576 counts/rev, respectively.
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. Resolution of the high--resolution
feedback devices depends on the motor type (SinCos or SinCoder
feedback) your system requires.
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).
