3.2.5 Manual pulse generator wiring
This section explains the wiring when a manual pulse generator is used.
When a manual pulse generator is used, parameter settings are required.
In the wiring shown below, the parameters are set as follows.
PARA 39 : Manual pulse generator Set to "1" : One pulse generator.
Set to "2" : Two pulses generator.
PARA 40 : Magnification ratio Set according to necessity. (1 to 255)
PARA 41 : Division Set according to necessity. (0 to 7: FX
2N
-20GM)
PARA 42 : Enable input One manual pulse generator can be changed over for the
X axis or the Y axis in the FX
2N
-20GM.
(X02 to X03: FX
2N
-10GM, X02 to X67: FX
2N
-20GM)
• When the manual pulse generator is used with FX
2N
-10GM, the operation becomes as
follows.
In FX
2N
-10GM, the difference is uncommonly generated in the number of pulses output
from the manual pulse generator and the numbers of pulses which FX
2N
-10GM con-
ted.(pattern 2)
However, the difference is not generated in the current value of the servo amplifier and
FX
2N
-10GM.
• Use the manual pulse generator of the NPN open collector type.
