End-of-Travel Mode
2 0
No feedback. This mode is used when the system has no motor drive
output.
2 1
A
ctuators with potentiometer feedback (MT, SF, HL, HF, HT, and UHT).
These actuators use a potentiometer to sense actuator position and have
adjustable end-of-travel and servo-center limits.
Caution: To prevent jamming of the actuator make sure the end-of-travel
limits are set correctly. Refer to page 85 for more information about
setting end-of-travel limits.
2 2
A
ctuators with limit switches (MM, MME, MN, and MNE). These
actuators use fixed limit switches to sense actuator position. Their end-
of-travel limits are factory set.
2 3
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 11, 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.
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.
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
