Delta DVP-20PM

9 Electronic Cam
In addition, for point-to-point switching pattern, if electronic cam max frequency (DD1840) is set as
0Hz and the value of deceleration time T
DEC
(D1837) is specified, electronic cam will decelerate to
stop. The below diagram indicates the difference between normal stop operation and stop operation
with deceleration.
2. Forward /Reverse running Pattern
To enable forward/reverse running pattern, bit 12, 11 of D1847/D1927/D1927 (work mode setting)
should be set ON (K3). In forward/reverse running pattern of multi-axis cam, the execution of Slave
will be in the same direction as Master. In reverse running operation, the execution will start again
from the end of the data when Master position 0 is reached. Therefore, please note that
forward/reverse running pattern can not be used with point-to-point switching pattern otherwise
error will occur. The below diagrams illustrate the execution of 2 electronic cam charts.
