c. Connecting the Force Sensor (Force/displacement-equipped specification)
The MM-400A can measure, as a force/displacement-equipped specification
function, force when connected with force sensor MA-520B/521B/522B,
pressure follow-up mechanism element P unit, or current/force sensor
MA-770A/771A.
Current/force sensor MA-770A/771A incorporates a current sensor (toroidal coil),
making it possible to measure force and current at the same time simply by
applying a force and passing a current.
Follow the steps described below to connect the force sensor.
For force sensor MA-520B/521B/522B
1) Plug the force sensor connector into the force sensor connector [FORCE] on
the rear panel of the MM-400A.
2) Perform a reset (ON setting) without applying loads to the force sensor.
CAUTION
Be sure to set the force sensor’s offset to “0” before measuring force. You
can set the offset to “0” by touching the FORCE 0 key on the SYSTEM
SETUP (2) screen. At this time make sure that no force is applied to the
sensor. For resetting a force, refer to Chapter 8, “n-2. SYSTEM SETUP (2)
Screen.”
