Setting Details
Use this bit to turn the power to the Servomotor ON or OFF.
After the mode is changed to Speed Control Mode, set this bit to 1
to start operation.
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 this parameter to 23 (VELO) to change operation to Speed Con-
trol Mode.
When this bit is set to 1 (ON) during an issue speed reference opera-
tion, the axis will decelerate to a stop.
Operation is resumed when this bit is set to 0 (OFF) when the axis is
being held.
When this bit is set to 1 (ON) during operation, the axis will deceler-
ate to a stop.
Set the torque feedforward amount during speed control.
Set the speed. 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 the speed reference. The same value is used
in both the forward and reverse directions.
This parameter allows the speed to be changed without changing
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 the acceleration rate or acceleration time.
Set the deceleration rate or 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 com-
pleted (i.e., when bit 0 in IW0C is 1).
