Sample Program: RAMP — Reversible Control with Dual Pulse Output
This program demonstrates a user program of the RAMP instruction to generate 30,000 pulses from output Q0 (forward
pulse) or Q1 (reverse pulse) while input I1 is off or on, respectively.

Description
Frequency range 100 to 10,000 Hz
10,000 Hz × 50% = 5,000 Hz
10,000 Hz × 20% = 2,000 Hz
10,000 Hz × 1% = 100 Hz
Reversible control with dual output
0 (forward) or 1 (reverse)
30,000
0 to 30,000
0: Pulse output OFF
1: Pulse output ON
0: Pulse output not complete
1: Pulse output complete
0: Steady pulse output
1: Changing output pulse frequency
0: Overflow not occurred
1: Overflow occurred
M8120 is the initialize pulse special internal relay.
When the CPU starts, seven MOV(W) instructions store parameters to
data registers D0 through D7.
D0 (operation mode): 1 (100 to 10,000 Hz)
D1 (steady pulse frequency): 50 (10,000 Hz × 50% = 5,000 Hz)
D2 (initial pulse frequency): 20 (10,000 Hz × 20% = 2,000 Hz)
D3 (frequency change rate): 1 (10,000 Hz × 1% = 100 Hz)
D4 (reversible control enable): 2 (reversible control with dual output)
D6 (preset value high word): 0
D7 (preset value low word): 30,000
When input I1 is off, D5 (control direction) stores 0 (forward).
When input I1 is on, D5 (control direction) stores 1 (reverse).
When start input I0 is turned on, RAMP starts to generate 30,000 output
pulses.
