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.

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.

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.

Initial Setting Function

Encoder Resolution Setting

The Encoder resolution per Resolver revolution can be set to 360 or

720.

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.

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 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

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.

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.

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.
