Initial
Setting
Pressing by pressing operation using force sensor uses a loadcell. Before the operation can be
started, parameters must be initialized. Set the four parameters listed in the table below as
shown in the area enclosed by the thick frame.

(1) Set of pressing control by loadcell
1) Set Parameter No.92 “Use of loadcell” to “1” “use”. If Parameter No.92 is set to “0” (Does
not use), the loadcell is invalid.
2) Set Parameter No.93 “Selection of pressing control” to “1” “pressing by pressing operation
using force sensor”. If Parameter No.93 is set to “0”, pressing by current limit is selected.

(2) Set of calibration of loadcell
Perform the settings to set when to have the calibration and to protect from the operation
without the calibration.
1) To measure precise force, proper loadcell calibration is required. Set Parameter No.117
“Automatic calibration at start” to “1” to perform calibration automatically or “0” to perform
calibration arbitrarily.
If it is set to automatic setting, the calibration is conducted once after the power is supplied
to the controller or software reset is held from the teaching tool such as PC software. The
calibration time is 10ms. The calibration does not lead the actuator to be operated.
2) Parameter No.118 can provide protection so that pressing may not be performed without
calibration. Set the parameter to “0”. Pressing without any calibration after power-on
causes alarm 0E1 “calibration error” to occur.
Setting the parameter to “1” allows pressing without calibration to be performed.
