MasterDelay
A system will execute cyclic electronic cam motion after it receives a signal which enables the cyclic
electronic cam motion. If users do not want to start an electronic cam immediately, and want to delay
the sending of pulses by the slave axis of the electronic cam, they can set the number of pulses the
master axis specified sends before the electronic cam is started by means of the MasterDelay input pin.
After a system receives a signal which enables electronic cam motion, the electronic cam motion will
not be started until the number of pulses the master axis specified sends is equal to the value of the
MasterDelay input pin.
The value of the MasterDelay input pin is 10.

MasterScaling
Users can set a ratio which is used to reduce/enlarge the number of pulses sent by the master axis
specified by means of the MasterScaling input pin. In the figure below, the value of the MasterScaling
input pin is 1/2. After the slave axis specified meshes with the master axis specified, the number of
pulses sent by the master axis specified will be 1/2 times the original number of pulses sent by the
master axis specified.
