CPM2A/CPM2C Pulse Output Functions
100
Up/Down Pulse Outputs
For CW output:
Pulses output from output number 01000 (Word 010, bit 00).
For CCW output:
Pulses output from output number 01001 (Word 010, bit 01).

CW operation
01001
CCW operation
Output mode: Continuous and Independent
Number of pulses: 1 to 16,777,215
Instructions: PULS(65) and ACC(––)
With PULS(65), the number of pulses is set (in independent mode only).
With ACC(––), the output mode, starting frequency, target frequency, and
acceleration/deceleration rate are set, and the pulse outputs are started.
From when the pulse outputs are started until they are stopped, they are
controlled at a constant-ratio frequency change.
