• Software Limit Function

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 SV.Pr26 (Software limit set up) against the position command input range.

You can prevent the work from colliding to the machine end caused by motor oscillation.

2)Applicable range

This function works under the following conditions.

	Conditions under which the software limit works
￿	• Either at position control mode or full-closed control mode￿
Control mode￿	SV.Pr02 = 0 : Position control￿
￿	SV.Pr02 = 6 : Full-closed control ￿
￿	(1) operating Normal auto tuning￿
￿	(2) After the last clearance of the position command input range (0 clearance), the movable range
￿	of the motor is within 2147483647 for both CCW and CW direction. ￿
￿	(3) at Servo-ON￿
Others	(2) when SV.Pr26 (Software limit setup) is other than 0. ￿
	￿
	Once the motor gets out of the (2) condition, the software limit protection will be invalidated
	until the later mentioned "5) Condition under which the position command input range is
	cleared" is satisfied. The position command input range will be 0-cleared when the motor gets
	out of the conditions of (3) and (4).
