2 I/O Application Procedures and Function Allocations
Parameter Setting
Internal Pulse • 4 ms
Control Cycle
• 1 ms
The following operation will be performed for the HUNDRED-MS TIMER (TIM/TIMX(550)), TEN-MS
TIMER (TIMH(015)/TIMHX(551)), and ONE-MS TIMER (TMHH(540)/TMHHX(552)) instructions if the
pulse control cycle is set to 1 ms.
• An error of up to one cycle time will occur in the timer PV accuracy.
• The timers will not operate correctly if the cycle time exceeds 100 ms.
• If the instructions above are in a task that is stopped or is not executed because it is jumped by a
JMP(004), CJMP(510), or CJPN(511) instruction, the timer will not operate correctly.

4 ms Set the control frequency of the pulse output.
This setting affects the response to speed
changes when accelerating or decelerating and
to change instructions. If 1 ms is set, accelera-
tion and deceleration will be performed in 1-ms
increments, providing a faster response for
change instructions for pulse outputs when
pulses are being output.
*Acceleration and deceleration rates are set in 4-
ms increments, but internal processing is per-
formed in 1-ms increments.
