Function of Gear Box #1 (Master E-Gear)

This function defines the relationship of the master axis and
E-Cam axis. When the master axis rotates one revolution, it
does not mean that E-Cam must rotate one revolution as well.
The master E-Gear can be set.

The master E-Gear (electronic gear) will change the resolution
of master pulse command.

E-Cam axis is a virtual axis.

When E-Cam axis rotates 360 degrees, it indicates that E-Cam
rotates one revolution also and the slave axis operates one
cycle as well.

The moving unit of the master axis is pulse number. The
resolution is determined by the command source.

P5-83 and P5-84 is used to set the scaling of command pulse.
After receiving the pulse number P of master axis, the axis of
E-Cam will rotate M cycles. P5-83=M, P5-84=P

P5-83 can be adjusted while engaging.
Function of E-Cam Curve

The E-Cam function defines the relationship of master and
slave axes. The related settings are saved in E-Cam curve.
When E-Cam rotates one revolution, the slave axis operates
one cycle.

Data array. The E-Cam curve is stored in the data array. P5-81
notes its start point where P5-82 +1 (720+1, maximum items
of one E-Cam curve) is for its length. P5-85 is the initial point
where the E-Cam engaged.

32-bit data with polarity (user unit is PUU)

It is used to magnify or minify E-Cam curve without changing
the setting value of the E-Cam curve.

Each data in E-Cam curve can be multiplied by this
parameter.

Range of P5-19 is:-2147.000000 ~ 2147.000000 with
minimum scale of 0.000001. The change or P5-19 will be put
into enforcement when the E-Cam re-engaged.

E-Cam curve can be a negative scaling. If P5-19 is set to
negative, the result will have a upside down curve compared
to P5-19 is a positive value.

When it is set to 0, E-Cam command will not output (always
be 0).

E-Cam curve can be divided into certain equal N parts (set by
P5-82, N>=5). For example, if N=5, there will be 6 points
recorded in the data array. Each division has 360/N degrees.

720 divisions are maximum number for one curve.
