(1) Speed change ratio upper/lower limit value
(a) The validate range (0.00 to 655.35[%]) of speed change ratio set in the
speed change ratio setting device is set.
(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 0 to
65535, i.e. 100 times the settings actually made: 0.00 to 655.35%.
(d) Set the speed change ratio upper/lower limit value as formula below.

(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.
Name Setting
range
Data register
D0 to D8191
(Note-1)
Link register
W0 to W1FFF
Motion register
#0 to #7999
Multiple CPU area device
U \G10000 to U \G(10000+p-1)
(Note-2)
(Note-1): 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 a
user device.
(Note-2): "p" indicates the user setting area points of the Multiple CPU high speed
transmission area for each CPU.
(c) The setting range is
"
Speed change ratio lower limit value
"
to
"
Speed change
ratio upper limit value
"
.
(3) Smoothing time constant
This is the time taken to reach 63[%] of the output axis speed.
