Timing Chart for Reversible Control Disabled
This program demonstrates a timing chart of the RAMP instruction when reversible control is disabled.

M50
I0
RAMP
S1
D200
D204 = 0 (reversible control disabled)
• When input I0 is turned on, RAMP generates output pulses star ting at the initial frequency designated by the value
stored in data register D202. While the output pulses are sent out from output Q0, internal relay M50 remains on.
• Operation modes 0 through 2: The pulse frequency increases according to the frequency change rate value stored
in data register D203.
• Operation mode 3: The pulse frequency increases as long as the frequency change time stored in data register
D203.
• While the output pulse frequency is on the increase, internal relay M52 remains on.
• When the output pulse frequency reaches the steady pulse frequency designated by the value stored in data regis-
ter D201, internal relay M52 turns off. When the output pulse frequency star ts to decrease, internal relay M52
turns on again.
• When the quantity of generated output pulses reaches the preset value designated by data registers D206 and
D207, RAMP stops generating output pulses. Then internal relay M50 and M52 turn off, and internal relay M51
turns on.
• If the parameter values in D200 through D207 (except for D204) are changed while generating output pulses, the
change takes effect when star t input I0 is turned on for the next cycle.
• If the value stored in D204 is changed after star t input I0 has been turned on, the change can take effect only
after the CPU star ts again.
• If star t input I0 is turned off before reaching the preset value, RAMP stops generating output pulses immediately,
then internal relay M50 turns off and internal relay M51 turns on. When input I0 is turned on again, RAMP restar ts
to generate output pulses for another cycle, star ting at the initial pulse frequency.
