Overview of Functions
Basic Operating Procedure
Enter the cam program (i.e., the cam output ON/OFF pattern) into the Cam Positioner. Use the bank selector signals to select a bank and turn the
RUN signal ON to start operation.

Modes
The 3F88L-160/162 Cam Positioners have three modes that can be selected from the mode selector switch on the front of the Positioner. They
are RUN, PRGM, and SET.
The following functions are supported in each mode.
RUN mode: Normal operation or adjustment operation
PRGM mode: Creating, editing, deleting, or testing a cam program
SET mode: Entering Cam Positioner parameters and compensation settings, teaching, or entering communications settings
SET (Setting) Mode
• Sets parameters for 3F88L-160/162
Cam Positioners.
• Sets various compensation values.
• Enables teaching.
• Sets communications.
• Adjusts the origin position.

Selecting Function Levels
The following function levels are supported by the Cam Positioner using the Function Level Selector setting.
Function Level 0 (Monitor Only)
•
Enables cam output and monitoring. You cannot write cam programs or set parameters in this level.
•
This level is used to prevent accidental changes to cam programs and parameters.
•
Functions that have already been set will operate from this level.
Function Level 1 (Basic Operation/Monitor Only)
•
You can write cam programs in addition to performing all level 0 functions from this level.
•
This level is used for basic operation.
Function Level 2 (All)
•
All Cam Positioner functions are enabled in this level.
•
This level provides access to the application functions.
Basic Functions
Cam Program Write Function
•
A cam program is used to set the cam output ON/OFF angles. Up
to 180 steps registered in 8 banks can be set per cam output at 360
resolution and up to 360 steps registered in 4 banks can be set per
cam output at 720 resolution.
•
Cam programs are generally input from the Operation Keys on the
front of the Cam Positioner, but a computer using the CompoWay/F
communications protocol can also be used to input them.
Note: 1.
One step is one ON/OFF combination for a cam.
2.
A bank is a program unit with cam outputs 1 to 32
constituting a set for the 3F88L-162, and cam outputs 1 to
16 constituting a set for the 3F88L-160. Switch banks to
change the program that is used for operation.
Application Functions
Origin Compensation
Any angular position can be changed to 0° to align the Cam
Positioner origin with the Encoder origin.
Origin Shift
If the TRIG input turns ON in RUN mode, the origin shift function
changes any angular position to 0° to align the Cam Positioner origin
with the Encoder origin.
Backlash Compensation
The detection angles can be offset in the clockwise and
counterclockwise directions to absorb the play in the mechanical
system.
Advance Angle Compensation
The advance angle compensation function advances the cam output
angle proportional to Resolver speed.
Cam Output Function
The cam output function is used to turn the cam outputs ON and
OFF according to the ON/OFF angle settings for each cam in the
bank specified by the BANK inputs while the START input is ON.
Cam Protection
The cam protection function applies levels of protection per cam or
per bank to prevent cam ON/OFF data from being accidentally
changed or deleted.
Monitor Function
The monitor function is used to monitor cam outputs and control I/O
status.
One-direction Function Setting
The one-direction function setting can be used to enable a cam
output in one direction only. It can be set for each cam.
Save Data
The save data function stores parameters and cam programs in
EEPROM memory. The memory is non-volatile, and does not require
battery replacement or any other maintenance.
Output Hold Function
The output hold function holds the previous cam output status when
you switch to the program mode or when an error occurs.
No. of Programs Check
The number of programs check is used to check the number of
programs and the origin compensation angle.
PV Output Function
The PV output function uses the cam output signals to output signals
to a Display Unit (M7E, M7F, etc.). It can be used to display the
present angle and speed on the Display Unit.
Initial Setting Function
Encoder Resolution Setting
The Encoder resolution per Resolver revolution can be set to 360 or
720.
Pulse Output Function
The pulse output function allows ON/OFF data set at regular
intervals for any bank or cam to be automatically set in memory.
Rotation Direction Setting
The direction in which the angle increases can be set to match the
rotation direction of the Cam Positioner and the Encoder.
Teaching
The teaching function allows you to enter Resolver angle data
directly as cam program settings while you manually operate the
Encoder.
Copy Function
The copy function allows you to set a master Cam Positioner so you
can copy cam programs, compensation values, and settings all at
once to other Cam Positioners.
Test Operation
The test operation allows you to change the ON/OFF angles in real
time and produce cam outputs in PRGM mode, ignoring the control
input signal status, to adjust the ON/OFF angles to match those of
the Encoder.
