CJ1-H/CJ1M CPU Unit Ver. 3.0 Upgrades Section 1-4
Expanded Acceleration/
Deceleration Rate Setting
The upper limit of the acceleration/deceleration rate has been increased from
2,000 Hz to 65,535 Hz for Pulse Output Instructions with accelerations/decel-
erations (ACC(888), PLS2(883), and ORG(889)).
Duty Ratios Set in 0.1%
Increments
The duty ratio for PWM(891) can now be set in 0.1% increments. The duty
ratio was set in 1% increments for the previous version.
Wider Range of
Applications for CW/CCW
Limit Inputs
Pulse outputs will stop when the CW/CCW limit input signals (reflected in
A54008, A54009, A54108, and A54109) turn ON. For the previous version,
the CW/CCW limit input signals were used only by ORG(889). With CPU Unit
Ver. 2.0, these signals can now be used with pulse output functions other than
origin searches. A new setting is also available for all functions that use the
CW/CCW limit input signals to specify whether the origin will remain estab-
lished or be undefined when a limit input signal turns ON.
Pulse Inputs
Pulse Frequency
Conversions
The pulse frequency input to high-speed counter 0 can be converted to a rota-
tional speed (r/min.) or the PV of the counter can be converted to the total
number of rotations.
High-speed Counters
Count Direction Flag The Count Direction Flag enables monitoring whether the count of the high-
speed counter is currently being incremented or decremented. The count in
the current cycle is compared with the count in the previous cycle to deter-
mine whether it is being incremented or decremented.
Continued Comparisons
when Resetting Counters
The comparison operation can be set to stop or continue when a high-speed
counter is reset. This enables applications where the comparison operation
can be restarted from a counter PV of 0 when the counter is reset. For the
previous version, the comparison operation stopped when the counter was
reset, requiring that the comparison operation be restarted from the ladder
program whenever resetting the counter.
