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.
