7.6 Changing During Operation (Operation Speed, Target Address)
Caution for speed change
• If the overridden (actual) operation speed is smaller than 1, the operation speed is handled as "1" in the
current speed unit.
• When "100%" is set to the override setting, the system operates at the preset operation speed.
• The operation speed can be changed during positioning operation.
The override function is invalid during deceleration after a STOP command or in positioning operation.
• When the operation speed is changed by the override function during interpolation operation, the
acceleration/deceleration time (interpolation time constant) changes according to the ratio by which the
operation speed changes.
→ For details, refer to the note in Section 7.2
4. Program description example
In the program below, the operation speed is changed as follows.
Contents of change
X035=ON
X-axis Changes the operation speed to "200.0%."
Y-axis Changes the operation speed to "200.0%."
X035=OFF
X-axis Changes the operation speed to "100.0%."
Y-axis Changes the operation speed to "100.0%."
Performing operations at the operation speed "200.0%"
