1) Advanced control functions
■
High-speed counter function
The built-in high-speed counter function supports four modes: two-phase input, UP, DOWN, and UP/DOWN.
The FP-M can read the input regardless of the scan time.
■
Pulse output function (transistor output type)
This function allows the output of a direct pulse (45 Hz to 4.9 k Hz) from the FP-M. In combination with a drive, a
motor can be controlled. As direct pulse is possible, an additional positioning controller is not necessary. As the
FP-M has two pulse outputs, it also supports motor drives with one input for forward driving and the other input for
reverse driving. To prevent incorrect forward/reverse driving, create an interlock circuit outside of the FP-M.
In addition, since the built-in high-speed counter can internally take the pulse output, no external wiring for feedback
control is required.

Application: Pattern output function
This function of the control board allows the setting
of a maximum of eight output patterns with 15 level
settings of the high-speed counter. Can also be
applied to multi-stage speed control with use of an
invertor.
