7-5-2	Outline
		The FQM1-MMP21 and FQM1-MMA21 Motion Control Modules can receive
		pulse inputs. The following table shows the processes that can be performed
		by combining the pulse input function with the high-speed counters to count
		pulse signals from a rotary encoder or other device and perform processing
		based on the counter PV.
				Process		Description
			Target value comparison			An interrupt task is executed when the high-speed
			interrupts			counter PV equals a preset target value.
			Bit pattern outputs for			When the high-speed counter PV is within a specified
			range comparisons			range, the user-set bit pattern specified in the compari-
						son table is output internally.
			Measurement			Movement in the high-speed counter or input pulse
			modes 1 and 2			counting speed can be displayed while monitoring the
						high-speed counter PV.
			High-speed counter PV			High-speed counters 1 and 2 each have a latch register.
			latch			Two latch inputs can be used to capture the high-speed
						counter PVs at high speed.

Note Interrupts cannot be generated for range comparisons. Only bit patterns are output.

The high-speed counter PV movement during a fixed time interval (equivalent to the travel distance) and the high-speed counter’s frequency can also be monitored as required.
