4.9.2.2 Input Signals
The M2DC series servo drive has 12 programmable digital inputs as well as 2 analog inputs.
Each of the inputs can be specified with different functions via the parameter settings. The functions are
as follows:
● Specified function signals: i.e. STEP/DIR signal, motor enable/disable signals.
● General purpose signal: In velocity mode, torque mode, Q program mode, or SCL mode, it is used as
general purpose signal with no specified functions.
