CPM2A/CPM2C Pulse Output Functions

Set Frequency and Start Pulse Outputs
Change Frequency
These functions set the output mode, the target frequency, the starting frequen-
cy, and the acceleration/deceleration rate, and they begin pulse outputs. They
can also be used to change the frequency, by accelerating or decelerating at the
specified acceleration/deceleration rate, if pulse outputs are already in progress
in continuous mode.
Setting the Frequencies, Acceleration/Deceleration, and Starting Pulse
Outputs in Independent Mode
Fixed at 000: Pulse output 0

Output mode
Specify the output mode.
000: Up/down pulse outputs, independent mode
002: Pulse + direction outputs, independent mode
Acceleration/deceleration rate (#0001 to #1000 BCD: 10 Hz to 10 kHz)
Target frequency (#0001 to #1000 BCD: 10 Hz to 10 kHz)
Starting frequency (#0000 to #1000 BCD: 0 to 10 kHz)
Register the data for each frequency.
The acceleration/deceleration rate is the increase or decrease in the fre-
quency every 10 ms.

Number of
pulses
In independent mode, the acceleration and deceleration
points are determined from the number of pulses, the
acceleration/deceleration rate, the target frequency, and
the the starting frequency.
