Setting Example Of Pulse Output (Frequency Change) - Panasonic FP7 User Manual

9.4 Execution Example of Pulse Output / PWM Output Function
(1) If the rising edge of the start signal is detected when the enable signal is on, pulses will be output.
(2) The forward rotation pulse is output.
(3) One pulse is omitted when the direction is switched.
(4) The reverse rotation pulse is output.
(5) When the enable signal turns off, the pulse output will turn off.
(Note 1) In this time chart, "OFF start" is selected for the pulse start logic.

Sample program
The external inputs (X140, X141, X142) are allocated to the enable (Y118), start (Y11C) and
direction switching (Y128) signals of pulse output respectively.

9.4.2 Setting Example of Pulse Output (Frequency Change)

■
Overview
The pulse output is performed in the direction distinction mode. It is controlled by the switch
input (X140/X141/X142/X143) connected to the 32-point input unit. If the start input (X141)
turns on when the enable input (X140) is on, the pulse output will start. The pulse output is
switched to that of the reverse direction by turning on the direction switching input (X142). While
the speed change input (X143) is on, the frequency of output pulse is changed.
