2.4 Input Specification
*1 In the case of a stepping motor, short-circuit the terminals ST1 and ST2 to change the
resistance from 3.3 k
Ω
to 1 k
Ω
.
*2 The positioning unit automatically judges the target (general-purpose input, manual pulse
generator input or interrupt input) based on parameters and programs, and automatically
changes the filter constant. (Interrupt inputs are available only in the FX
2N
-20GM.)
The maximum response frequency of the manual pulse generator is 2 kHz.
