(b) When the setting value of speed change ratio setting device is greater than
the speed change ratio upper limit value, an operation is executed by a
speed change ratio clamped at the upper limit value.
When the setting value of speed change ratio setting device is smaller than
the speed change ratio lower limit value, an operation is executed by a
speed change ratio clamped at the lower limit value.

(c) The speed change ratio upper/lower limit value is set in the range of 1 to
10000, i.e. 100 times the settings actually made: 0.01 to 100%.
(d) Set the speed change ratio upper/lower limit value as formula below.
(Speed change ratio lower limit value)
(2) Speed change ratio setting device
(a) The device to set a speed change ratio of speed change gear.
(b) The following devices can be used as the speed change ratio setting
devices.

Data register
Link register
(Note) : D800 to D1559 are dedicated devices of virtual servomotor axis,
synchronous encoder axis and output module "cam" in the virtual mode.
Unused areas of virtual servomotor axis and cam axis can be used as an
user device.
(c) The setting range is
ratio upper limit value
(3) Smoothing time constant
This is the time taken to reach 63[%] of the output axis speed.
