Caution
Use the motor so that actual torque stays in the continuous running range shown in "S-T
characteristic" of the motor. For the S-T characteristics, see P.7-56 Motor characteristics
(S-T characteristics).
Software Limit Function (Error code No.34.0)
1) Outline
You can make an alarm stop of the motor with software limit protection (Error code
No.34) when the motor travels exceeding the movable range which is set up with
Pr5.14 (Set up of software limit) against the position command input range.
You can prevent the work from colliding to the machine end caused by motor oscilla-
tion.
2) Applicable range
This function works under the following conditions.
Control mode
Others
3) Cautions
• This function is not a protection against the abnormal position command.
• When this software limit protection is activated, the motor decelerates and stops ac-
cording to Pr5.14 (Sequence at alarm).
The work (load) may collide to the machine end and be damaged depending on the
load during this deceleration, hence set up the range of Pr5.14 including the decel-
eration movement.
• This software limit protection will be invalidated during the trial run and frequency
characteristics functioning of the PANATERM.

Conditions under which the software limit works
• Position control, Full-closed control
• Should be in servo-on condition
• Input signals such as the deviation counter clear and command input
inhibit, and parameters except for controls such as torque limit setup,
are correctly set, assuring that the motor can run smoothly.
