3) Attach the current/force sensor to the welding machine’s electrodes.
When attaching the sensor, be careful with the following:
• Be sure that the center of
the sensor’s detection area
is aligned with the centers of
the welding machine’s
electrodes.
• Be sure that the force is
applied perpendicularly to
the sensor.
For force sensor of follow-up mechanism element
1) Plug the conversion cable 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
When using a force sensor, be sure to set the force sensor’s offset to “0”
before measuring force. When using a force sensor built in a head, set the
offset to “0” with the force applied to the head stopped. 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.”
3) Set a force of the follow-up mechanism element with a knob.
current/force sensor
between the
electrodes, and apply
force and current.
