A
ctuators with limit switches (MME and MNE). These actuators use fixed
limit switches to sense actuator position. Their end-of-travel limits are
factory set.

A
ctuators with limit switches (MX). These actuators use fixed limit
switches to sense actuator position. Their end-of-travel limits are factor
y
set.
Note: The default setting for this parameter is 4. After resetting all parameters to their default
values (refer to page 12, troubleshooting item 5) you must set this parameter to 0, 1, 2, or 3
before setting other parameters and/or operating the system.
Input A Polarity
3 0
The actuator will move Out when edge detector A is unblocked, or the
digital line guide’s sight point is to the left of the line or edge it is
following. This is the default setting.
3 1
The actuator will move Out when edge detector A is blocked, or the
digital line guide’s sight point is to the right of the line or edge it is
following.
Note: This value is set by the Polarity Settings Screen button.
Input B Polarity
4 0
The actuator will move Out when edge detector B is unblocked, or the
digital line guide’s sight point is to the left of the line or edge it is
following.
4 1
The actuator will move Out when edge detector B is blocked, or the
digital line guide’s sight point is to the right of the line or edge it is
following. This is the default setting.
Note: This value is set by the Polarity Settings Screen button.
Servo Gain
5 4 0
This parameter determines the response time and accuracy of the
system. In Automatic mode, the system produces a motor drive voltage
proportional to web position error. Higher gain will increase the drive
voltage at a given position error. For best response time and accuracy,
set the servo gain to the highest value that does not produce excessive
overshoot or oscillation. The default value is 40.
Range: 0 to 255
Note: This value is set by the Controller Settings Screen button.
Maximum Deadband
6 1 0
The maximum deadband is a zone around the sensor guide point where
the motor drive is turned off. The higher the Maximum Deadband value is
set, the farther the web edge or line must move away from the guide
point before the motor drive is turned on. This parameter is typically used
to compensate for edge curl and web flutter. The Maximum Deadband
value must be higher than the Minimum Deadband value. The default
value is 10.
Range: 0 to 100
Note: This value is set by the Controller Settings Screen button.
