Changing During Operation (Operation Speed, Target Address)

7.5.1

Changing the operation speed with override function

This function is possible to change the operation speed at an arbitrary timing through the override setting
value (0.1 to 3000.0%).
1. To use the override function
Set the following setting.

Override setting
2. Applicable positioning operations
• Operations applicable to the override function
- Mechanical zero return (at high speed)
- JOG operation
- 1-speed positioning operation
- Interrupt 1-speed constant quantity feed
- 2-speed positioning operation
- Interrupt 1-speed constant quantity feed
- Interrupt stop
- Variable speed operation
- Multi-speed operation
- Linear interpolation
- Linear interpolation (interrupt stop)
- Circular interpolation

4. Caution for speed change
• If the overridden (actual) operation speed is smaller than 1, operation speed handles on "1" in the current
speed unit.
• If "100 (%)" is specified as an override, the speed does not change.
• 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.
