Delays may occur in the t1 timing time due to the operation status of other axes.
Position control by manual pulse generator operation
In manual pulse generator operation, the position is moved by a "manual pulse
generator 1 pulse movement amount" per pulse.The current feed value in the
positioning control by manual pulse generator operation can be calculated using
the expression shown below.
Current feed value = Number of input pulses
× [Cd.20] Manual pulse generator 1 pulse input magnification
× Manual pulse generator 1 pulse movement amount
[Pr.1] Unit setting mm inch degree PLS

amount
0.1µm 0.00001inch 0.00001degree 1PLS
For example, when "[Pr.1] Unit setting" is mm and "[Cd.20] Manual pulse
generator 1 pulse input magnification" is 2, and 100 pulses are input from the
manual pulse generator, the current feed value is as follows.
100 × 2 × 0.1 = 20 [µm] ("[Md.20] Current feed value"=200)
The number of pulses output actually to the servo amplifier is "Manual pulse
generator 1pulse movement amount/movement amount per pulse".
The movement amount per pulse can be calculated using the expression shown
below.
Movement amount per pulse =
[Pr.3] Movement amount per rotation(AL)
[Pr.2]
Number of pulses per rotation(AP)
[Pr.4] Unit magnification(AM)
For example, when "[Pr.1] Unit setting" is mm and the movement amount per pulse
is 1μm, 0.1/1 = 1/10, i.e., the output to the servo amplifier per pulse from the manual
pulse generator is 1/10pulse. Thus, the Simple Motion module outputs 1pulse to the
servo amplifier after receiving 10pulses from the manual pulse generator.
Speed control by manual pulse generation operation
The speed during positioning control by manual pulse generator operation is a
speed corresponding to the number of input pulses per unit time, and can be
obtained using the following equation.
Output command frequency = Input frequency
