(6) 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
Manual pulse generator 1 pulse
movement amount
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 [m] = 200 [Current feed value]
The number of pulses output actually to the drive unit is "Manual pulse generator 1 pulse movement
amount/movement amount per pulse
amount per pulse is 1m, 0.1/1 = 1/10, i.e., the output to the drive unit per pulse from the manual pulse generator
is 1/10 pulse. Thus, the LD75 outputs 1 pulse to the drive unit after receiving 10 pulses from the manual pulse
generator.
