1-1-3 Modes
• The 3F88-L160 and 3F88L-162 Cam Positioners have three modes: RUN, PRGM, and SET. These
are set using the mode selection switch on the front of the Unit. The functions of each mode are out-
lined below. (Refer to 3-2 Mode, Functions, and Display.)
RUN mode: Operation and compensation.
PRGM mode: Creation, editing, deletion, and trial operation of cam programs.
SET mode: Unit parameters and various compensation value settings, teaching, and communica-
tions settings.
1-1-4 Selecting the Function Level
• Three function levels are available to limit Cam Positioner functions. (Refer to 3-4 Selecting Function
Levels.)
Function Level 0 (Monitor Only)
Cam output and monitoring are enabled. Cam programs are write protected and parameter settings
cannot be made. This function level is designed to prevent inadvertent changes to the cam program
or parameters.
Function Level 1 (Basic Operation/Monitor Only)
In addition to the functions available at function level 0, cam programs may be edited. This function
level is used for basic operation.
Function Level 2 (All Functions)
All Cam Positioner functions are enabled. This function level is for using applied functions.
1-1-5 Basic Functions
H Cam Program Write Function
• Cam programs set the angle at which the cam output is turned ON and OFF. Up to 180 steps can be set
and up to 8 banks registered for 360 resolution and up to 360 steps and 4 banks for 720 resolution can
be set for each cam output point. (Refer to 3-5-3 Cam Program Creating and Checking.)
• Cam programs are normally input by using the operation keys on the front of the Unit but settings can
be made from a personal computer by using a special communications protocol (CompoWay/F). (Re-
fer to Chapter 4 Communications.)
Note 1. A step is one ON/OFF combination for one cam.
Note 2. A bank is a program unit made up of cam outputs 1 to 32 for the 3F88L-162 and cam outputs 1
to 16 for the 3F88L-160. By changing the bank, the program that will be operated will change.
H Cam Output
• While START input is ON, this function turns cam outputs ON and OFF in the bank specified at BANK
input according to the ON/OFF angles set for each cam.
H Monitor
• Monitors cam output and control I/O status. (Refer to 3-5-7 I/O Monitor Function.)
