SETTINGS AND ADJUSTMENTS
Before Setting Stroke
1. Remove the top cover from the motor.
2. Disconnect the controller from the motor.
3. For models with an internal transformer (line voltage
motors), ensure that power (and nothing else) remains
connected to the motor.
IMPORTANT
Detach linkage from motor before adjusting stroke.
Adjustable Stroke
Series 61 Adjustable Stroke
When viewing from the power end of the motor, the stroke
potentiometer is to the far left. To set the stroke to 160°
(maximum position) turn the potentiometer fully clockwise
, using a 1/8 in. straight-blade screwdriver. To set the
stroke at 90° (minimum position) turn the potentiometer fully
counter-clockwise
. Setting the potentiometer anywhere
between fully clockwise and fully counter-clockwise will set the
stroke between 160° and 90°.
Series 62 Adjustable Stroke
When viewing from the power end of the motor, the stroke
potentiometer is to the far left. The sensitivity potentiometer is
to the far right. To set the stroke to 160° (maximum position)
turn both potentiometers fully clockwise
, using a 1/8
inch straight-blade screwdriver. To set the stroke at 90°
(minimum position) turn both potentiometers fully counter-
clockwise
. Setting the potentiometer anywhere between
fully clockwise and fully counter-clockwise will set the stroke
between 160° and 90°.
CAUTION
Careless Installation Hazard.
Use of excessive force while adjusting cams
damages the motor.
To avoid damaging motor end switches, set cams by
moving only the screwdriver top.
CAUTION
Equipment Damage Hazard.
Can damage the motor beyond repair.
Never turn the motor shaft by hand or with a wrench.
Forcibly turning the motor shaft damages the gear
train and stroke limit contacts.

Feedback Potentiometer
Configuration (Series 62
®
TRADELINE
Motors Only)
Select and install a shunt resistors to obtain the appropriate
feedback characteristic for your application. See the
Specifications section for details on feedback resistance
without a shunt resistor.
NOTE: Due to circuit protection components, the resis-
tance cannot be read directly, use a voltage
divider to read the position of the motor.
• Linear feedback provides linear indication of shaft position
with no shunt resistor.
• Slaving a Series 90 Motor requires full-stroke feedback
resistance of 142 ohms. Select and attach the proper shunt
resistor across terminals Y and G (see Table 2 and Fig. 13).
