DMC-1400 Series Command Reference EM ā 79
EM FUNCTION: Cam cycles
DESCRIPTION:
The EM command is part of the ECAM mode. It is used to define the change in position over
one complete cycle of the master. The field for the master axis is the cycle of the master
position. For the slave, the field defines the net change in one cycle. If a slave will
return to its original position at the end of the cycle, the change is zero. If the change is
negative, specify the absolute value.
ARGUMENTS: EM n,m where
