7 Applied Functions
*2 The term "During deceleration" means the distance until the motor decreases its speed to 30 mm/s or less
from the normal operation. Once it decelerates to 30 mm/s or lower, the operation conforms to the description
for "post-stopping", regardless of the actual motor speed.
*3 "Immediate Stop" means that the motor stops immediately by using controls while the servo is kept ON. The
force limit at this time is controlled by the Immediate Stop Force (3511 hex) set value.
POT or NOT opens.
Precautions for Correct Use Precautions for Correct Use
• An immediate stop forces the motor to decelerate quickly, which momentarily causes a large
position error in position control. This may result in an Error Counter Overflow (Error No. 24.0)
or an Overrun Limit Error (Error No. 34.0). If an error occurs, set the Following error window
(6065 hex) and the Overrun Limit Setting (3514 hex) to appropriate values.
• A Command Warning (Warning No. B1 hex) will occur if a command is given in the drive
prohibition direction while the motor is stopped (i.e., decreases the speed to 30 mm/s or lower)
and the Drive Prohibition Input is open.
Additional Information
While the Positive Drive Prohibition Input (POT) is open, the motor cannot be driven in the
positive direction, but it can be driven in the negative direction. Conversely, while the Negative
Drive Prohibition Input (NOT) is open, the motor cannot be driven in the negative direction, but it
can be driven in the positive direction.
0
 Immediate Stop Force (3511 Hex)
This is the force limit when the Stop Selection for Drive Prohibition Input (3505 hex) is set to 2, and the
motor decelerates due to a drive prohibition input.
The settable range is 0 to 500% in units of 0.1%. When it is set to 0%, the normal force limit is used.
