Specification
(1) Engineering tool
Write/read/verify to cam storage area
(2) Via buffer memory (Cam data operation function)
Write/read to cam storage area and cam open area
Automatically generate the following cams.
• Cam for rotary cutter [RD77MS]
• Cam for rotary cutter (central reference) [RD77GF]
• Easy stroke ratio cam [RD77GF]
• Advanced stroke ratio cam [RD77GF]
Calculate the cam position by the program.
Used to calculate the cam position for the synchronous control initial position before starting synchronous
control.
