Description
Composite speed
Composite speed (Initial speed, maximum speed) (Hz) <K constant>
Initial speed
1.5 Hz to 100 kHz [K1 to K100000]
Fmin (Hz)
(However, for 1.5 Hz, the angle is 0 degree or 90 degrees only. Also,
for specifying 1.5 Hz, specify K1.)
● When the component speed becomes lower than the minimum
speed in each frequency range, it will be a corrected component
speed.
● Do not set 60 kHz or more when using any two of the high-speed
counter, periodical interrupt and PLC link are used simultaneously.
● When the initial speed is set to the maximum speed, the pulse
output is performed without acceleration and deceleration.
● Specify the composite speed to make the component speed of
each axis be 1.5 Hz or more.
Composite speed
● Composite speed (Initial speed): 30 kHz or less
Maximum speed
Notes on the specification of composite speed (initial speed)
Fmax (Hz)
When each initial component speed of CH0 and CH2 is not 1.5 Hz or
more by the following arithmetic expression, the path may not be
linear. (When the following formula is not satisfied)
∆x: Channel whose distance of (target value - current value) is short
∆y: Channel whose distance of (target value - current value) is long
Acceleration / deceleration time (ms) <K constant>

In the case of 0, the pulse output is performed at the initial speed

(composite speed) without acceleration and deceleration.

For the incremental mode, set the target value of the axis that is
not activated to 0.
For the absolute mode, set the target value of the axis that is not
activated to the same as the current value.
