Economical, Simple Servo System
ES Series

 |
- No manual potentiometer adjustment is
necessary. The servo system automatically
responds to changing load conditions with rapid speed
adjustments.
- The velocity control range is 1:1000. For the
motor stop status, the "velocity 0,"
"servo lock," or "external
brake" status can be selected.
- The shaft ends and mounting dimensions of the
K-series motors are identical with those of
general-purpose motors. The maximum torque
settings of K-series motors are restricted at
150%. Thus, the K-series motors can, for
performance enhancement, replace general-purpose
motors without requiring any modifications to
the existing mechanical systems.
