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.
PRGM (Programming) Mode

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
Application Functions
Cam Program Write Function
Origin Compensation
• 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.
Any angular position can be changed to 0° to align the Cam
Positioner origin with the Encoder origin.
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.
Backlash Compensation
Cam Output Function
The advance angle compensation function advances the cam output
angle proportional to Resolver speed.
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.
Monitor Function
The monitor function is used to monitor cam outputs and control I/O
status.
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.
No. of Programs Check
The number of programs check is used to check the number of
programs and the origin compensation angle.
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.
The detection angles can be offset in the clockwise and
counterclockwise directions to absorb the play in the mechanical
system.
Advance Angle Compensation
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.
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.
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.
PV Output Function
Initial Setting 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.
Encoder Resolution Setting
Pulse Output Function
The Encoder resolution per Resolver revolution can be set to 360 or
720.
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
Teaching
The direction in which the angle increases can be set to match the
rotation direction of the Cam Positioner and the Encoder.
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.
5
3F88L-160/-162
Adjustment Operation
The adjustment operation allows you to change the ON/OFF angles
in real time under normal operating conditions (i.e., while producing
cam outputs) to adjust the ON/OFF angles to match those of the
Encoder.
Communications
The Cam Positioner has a communications port that conforms to
CompoWay/F form B. Using communications allows you to read and
write cam programs or monitor the present angle and speed via
communications through this port.
Note: CompoWay/F is an integrated protocol used for OMRON
general-purpose serial communications. It uses a uniform
frame format and the factory interface network service (FINS)
command structure widely used by OMRON products, such as
Programmable Controllers, to facilitate communications
between multiple components or between computers and
components.
