Setting Details
Use this bit to turn the power to the Servomotor ON or OFF.
Set this bit to 1 before setting OW08 to 34 (EX_FEED).
0: Servo OFF, 1: Servo ON
Use this bit to change the speed control loop between PI control and
P control.
0: PI control, 1: P control
Select the stop method to use when a command is canceled.
0: Stop according to the Linear Deceleration Rate/Deceleration
Time Constant parameter
1: Stop immediately
Select the speed unit, acceleration/deceleration unit, and filter type.
Set the signal to use for external positioning.
2: Phase-C pulse, 3: /EXT1, 4: /EXT2, 5: /EXT3
External positioning with jogging is started when this parameter is
set to 34 (EX_FEED). External positioning with jogging stops and the
axis decelerates to a stop when this parameter is set to 0.
When this bit is set to 1 (Cancel command ON) during external posi-
tioning with jogging, the axis will decelerate to a stop.
Set the travel direction for external positioning with jogging.
0: Forward, 1: Reverse
Set the speed for external positioning with jogging. This parameter
can be changed during operation. The unit depends on the set value
of bits 0 to 3 in OW03.
Set the upper speed limit as a percentage of the rated speed. This
value is an absolute value. It is used in both the forward and reverse
directions.
Set the torque limit for external positioning with jogging. This param-
eter can be changed during operation. The unit depends on the set
value of bits C to F in OW03.
This parameter allows the feed speed to be changed without chang-
ing the value of OL10.
Set the value as a percentage of the Speed Reference Setting. This
parameter can be changed during operation.
Setting range: 0 to 32,767 (0% to 327.67%)
Setting unit: 1 = 0.01%
Example: Setting for 50% = 5,000
Set this parameter to the value for which bit 1 in IW0C will
change to 1 (Within positioning completed range).
Set this parameter to the value for which bit 3 in IW0C will
change to 1 (Within near position range). Bit 3 changes to 1 when
the absolute value of the difference between the reference position
and the feedback position is within the range that is specified here.
Set the jogging acceleration rate with the acceleration rate or the
acceleration time.
Set the jogging deceleration rate with the deceleration rate or the
deceleration time.
Set the acceleration/deceleration filter time constant. Exponential
acceleration/deceleration or a moving average filter can be selected
in bits 8 to B in OW03. This setting can be changed only when
distribution has been completed (i.e., when bit 0 in IW0C is 1).
Set the travel distance after the external positioning signal is input.
