Changing the operation speed with the operation speed change function

This function is possible to change to the specified new operation speed at an arbitrary timing.
However, the speed does not change during mechanical zero return after detection of the near point DOG and
start of deceleration to the creep speed.
1. To make speed change valid
Specify the following settings.
Setting item
Change command in operation disabled
Speed change value
Speed change command in positioning operation
2. Applicable positioning operations
• Operations applicable to the operation speed
change function
- Mechanical zero return (at high speed)
- JOG operation
- 1-speed positioning operation
- Interrupt 1-speed quantity feed
- 2-speed positioning operation
- Interrupt 2-speed quantity feed
- Interrupt stop
- Multi-speed operation
- Linear interpolation
- Linear interpolation (interrupt stop)
- Circular interpolation
3. Operation
Speed change command in
positioning operation
Operation speed change processing
4. Cautions for speed change
• After operation speed change, if STOP command is turned ON during positioning operation, the next
operation speed becomes the changed speed.
• The operation speed can not change in the following statuses.
- During deceleration by STOP command
- During automatic deceleration in position control
• If an operation speed larger than the maximum speed is specified for the speed change value, a setting
error occurs and the operation speed is controlled at the maximum speed.
• To change the speed at interpolation control, the speed change value has to be set in the X-axis setting.
• The operation speed does not change during mechanical zero return (at creep). The speed change
command is ignored.
