8.4.4 Cam curve list
Cam curves which can be used in the VIRTUAL mode are discussed below.
(1) Cam curve characteristics
The cam curve characteristics are compared in Table 8.6 below.

(2) Free-form curve
The spline interpolation function can be used to create free-form cam
curves.
8.4.5 Creation of cam data by user
There are two ways to create of cam data by user.
• Creating cam data at IBM PC started up with SW0IX-CAMPE.
• Creating cam data at personal computer other than IBM PC.
(hereafter referred to as PC)
(1) Creating cam data at IBM PC started up with SW0IX-CAMPE.
Cam data is created by creating a cam curve for 1 cam rotation using at the
free- form curve or one of the cam curves shown in section 8.4.4.
For details regarding the creation of cam curves at IBM PC which have
been started up with the SW0IX-CAMPE software, refer to the SW2SRX-
GSV22PE/SW0IX-CAMPE Operation Manual.
(2) Creating cam data at PC other than IBM PC.
Cam data is created in accordance with the format of cam data stored in the
block No. 10 to No. 18 of the extended file register area of the memory
cassette.
