Delta DVP-20PM

9 Electronic Cam
Same as single-axis cyclic electronic cam, multi-axis cam is enabled by setting b13 of D1846 as ON. In
addition to setting D1846, work modes of each axis should also be set up and enabled, and C200
should be activated for counting pulses of Master.
1. D1846
Set b13 of D1846 to ON (D1846 =H’2000) to enable multi-axis cam.
2. Set up work modes (X-D1847 Y-D1927 Z-D2007)
For multi-axis cam, b12 and b11 in D1847 should be set to 01 (bit11=1). When the Y-axis and the
Z-axis are applied, bit11 in D1927 and D2007 should also be set to 1.
3. C200/C204
Enable C200/C204 after setting up counting mode of C200/C204. Multi-axis E-CAM applies
C200/C204 as the input signal of Master. Counting mode of C200/C204 should match the pulse
input pattern of Master.

are controlled by PG0. The input signals for C204 are controlled by A1±/B1±, and the reset signals
for C204 are controlled by PG1.
