S1+3 Frequency Change Rate / Frequency Change Time
When S1+0 is set to 0 through 2, the value stored in the data register designated by operand S1+3 specifies the rate of
pulse output frequency change for a period of 10 ms in percent of the maximum of the frequency range selected by S1+0.
When S1+0 is set to 0 (10 to 1,000 Hz) or 1 (100 to 10,000 Hz), valid values for operand S1+3 are 1 through 100, thus the
frequency change rate can be 10 to 1,000 Hz or 100 to 10,000 Hz, respectively. When S1+0 is set to 2 (1,000 to 20,000
Hz), valid values for operand S1+3 are 1 through 20 and the S1+3 value multiplied by 5 determines the frequency change
rate, thus the frequency change rate can be 1,000 to 20,000 Hz.
When S1+0 is set to 3, the value stored in the data register designated by operand S1+3 determines the frequency change
time. Valid values are 10 through 10,000 in increments of 10, thus the frequency change time can be 10 to 10,000 ms.
Mode 0 or 1: Frequency change rate in 10 ms (Hz)
Mode 2: Frequency change rate in 10 ms (Hz)
Mode 3: Frequency change time (ms)
The same frequency change rate and frequency change time apply to the accelerating and decelerating periods of the trap-
ezoidal frequency change pattern.

If the value stored in the data register designated by operand S1+4 is changed after the start input for the RAMP instruc-
tion has been turned on, the change can take effect only after the CPU starts again.

Output Q0 generates output pulses; used for single-direction control.
Output Q0
Output Q1 can be used for PULS2, PWM2, ZRN2, or ordinary output.
Output Q0 generates output pulses, and output Q1 generates a direction con-
trol signal.
Output Q0
Output Q1
Output Q1 turns on or off depending on the value stored in data register des-
ignated by operand S1+5 (control direction): 0 for forward or 1 for reverse.
Output Q0 generates forward output pulses, and output Q1 generates reverse
output pulses.
Output Q0
(Forward)
Output Q1
(Reverse)
Output Q0 or Q1 generates output pulses alternately depending on the value
stored in data register designated by operand S1+5 (control direction): 0 for
forward or 1 for reverse.
