5.4  Manual Pulse Generator Operation
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
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] ("[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.
For example, when "[Pr.1] Unit setting" is mm and the movement amount per pulse is 1 m, 0.1/1 = 1/10, i.e., the output to the 
servo amplifier per pulse from the manual pulse generator is 1/10 pulse. Thus, the Simple Motion module outputs 1 pulse to 
the servo amplifier after receiving 10 pulses 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  [Cd.20] Manual pulse generator 1 pulse input magnification
