1: SAFETY
1.2 Safety Considerations
Proper and Safe Use of Product
Fail Safe e-Stop Recommendations
Means for a fail safe e-stop is highly recommended to ensure equipment and personal safety. The
e-stop should provide a means to remove main power from the actuator to cease and prevent any
unwanted motion.
Device Damage Prevention
To prevent permanent damage to the device, proper care should be taken not to exceed published
voltage, current, temperature, and load/force ratings. In addition, proper mechanical assembly and
proper wiring should be verified and safety measures checked before applying power to the complete
equipment package.
Personal Safety
During normal operation the actuator can become hot, especially the motor housing. In addition, the
case ground should be tied to an earth ground to prevent the presence of case voltage.
During normal operation, the actuator rod travels in and out creating a possible pinch point.
Proper guarding and signage must be used prevent entry into possible pinch zones and contact with
hot surfaces. It is highly recommended to display proper safety notices and implement proper safety
measures to prevent contact with hot surfaces.
Handling and Unpacking
When unpacking and handling the actuator, care should be taken not to drop the actuator as this can
damage the connectors, internal electronics, or cause misalignment of the actuator feedback device.
Damage the internal mechanical components may cause poor performance or render the actuator
non-functional. Since this is an electromechanical device, proper ESD measures should be taken to
avoid static electricity from contacting the signal and power lines of the device. as this can damage
the internal mechanical components rendering the actuator damaged or non-functional.
Packing and Transport
NOTE!
Package actuator to prevent damage during transport. It is recommended that the actuator be
returned in its original packaging. If the original packaging is not available, the follow these
recommendations.
1. Foam in place if possible.
2. Reinforce ends of box with multiple layers of cardboard or wood to prevent the actuator from
breaking through the packaging during shipment.
3. Support the connectors or cables so that enough packaging or foam is in place to prevent
shipping damage.
4. It is best to ship one unit per container because individual items that are not isolated with stable
packaging (foam in place) from each other often get damaged during shipment.

Tolomatic User Guide: IMA-S Integrated Motor Rod-Style Actuator - Stainless Steel
• 9 •
1: SAFETY
5. When shipping more than one unit in a single container, it is recommended to foam in place to
prevent damage during shipping to both the units and the packaging.
6. Add the RMA on the outside of the packaging. Failure to do so will delay processing.
Modifications to the Equipment
WARNING!
The manufacturer takes no responsibility whatsoever if the equipment is modified or if the equipment
is used in any way beyond performance specifications. Unauthorized modifications or changes to the
equipment are strictly forbidden and void all warranties.
Repair and Maintenance
WARNING!
All power and supply media must be shut OFF before any work is performed on any equipment that
is associated with the actuator. The only field maintenance that may be performed on the IMA-S
include lubrication and replacement of the rod seal cartridge. All other repair or maintenance for the
IMA-S must be performed at Tolomatic.
Requirement Regarding Personnel
NOTE!
All personnel must be completely informed regarding all safety regulations and the function of the
equipment.
Risk Area and Personnel
When installed, pinch points are generated capable of damaging forces. The risk area surrounding
the actuator must either be guarded or clearly marked, including display signage in accordance with
all applicable national and international legal requirements. The risk area must be protected by a
safety system that stops the equipment if anyone enters the risk area. Personnel who enter the risk
area must be authorized, trained and qualified for the different tasks inside the risk area.

The IMA-S series actuators are hygienically designed linear actuators with integrated servo motors
designed for precise linear positioning. These actuators are designed for the food and beverage
processing industry and feature 316 stainless steel construction, IP69K ingress protection, blue seals/
O-rings, and hygienic fasteners/cord grips allowing for open machine designs and clean-in-place
compatibility. The product line also includes the IMA-SA model which incorporates an internal anti-
rotate feature eliminating the need for an external guidance mechanism making it a perfect actuator
for applications such as volumetric filling and pumping.
The IMA-S series integrates either a roller screw or ball screw technology with a servo motor and
variety of feedback options including absolute multi-turn, incremental, and resolvers to allow for easy
integration with most servo drives. The servo motor drives the ball or rollerscrew and converts rotary
motion into linear movement. The linear motion extends/retracts the thrust rod within the linear
actuator housing.
NOTE IMA-S actuators are non-braking. When there is no current/torque input the thrust rod
can be moved freely. An internal integrated brake option is available if the motion system requires
the actuator to hold position in when no current/torque is input to the actuator

NOTE!
Be sure to completely follow all recommendations in 1.2 Safety Considerations.
Cable Routing
Over time, liquid contaminants such as oil and cleaning solutions may accumulate on the cables and
onto the cable glands. To minimize the introduction of contaminants to the cable glands, mounting
the actuator with the cable gland down is best. Mounting with the cable gland to the side requires a
bend or drip loop. It is not recommended to the mount the actuator in an orientation that faces the
cable gland upwards. If mounting the actuator with the cable gland facing upwards is unavoidable,
the cable should be routed with a drip loop prior to entering the cable gland.
Examples are shown depending on the orientation of the cable glands. Units mounted with the cable
glands on the bottom surface of the actuator require no looping.

WARNING!
Before installation and commissioning of the equipment, this manual and all accompanying
manufacturer documents and manuals MUST be completely read by the appropriate personnel. All
warning texts must be given special attention.
4.1 General Operation
The IMA-S actuator functions by translating the rotary motion of the integrated brushless servo motor
into linear motion using a screw mechanism. The linear travel, speeds and forces are controlled in
conjunction with a servo drive.
When ordered, the IMA-S actuator can be configured with any one of the following feedback devices:
Absolute multi-turn HIPERFACE DSL, absolute multi-turn HIPERFACE, absolute multi-turn EnDat2.2,
incremental and resolver. Please confirm that the servo drive supports the selected feedback protocol.
The relationship between the rotary motion of the motor and the linear motion of the actuator
corresponds to the following relationships:
Linear distance traveled = (motor revolutions) * (screw lead)
Linear Speed = ([motor RPM]/60) * (screw lead)
Linear Thrust (kN) = Motor torque (Nm) * 2 * π * pitch (rev/mm) * screw efficiency
or
Linear Thrust (lbf) = Motor torque (in•lb) * 2 * π * pitch (rev/in) * screw efficiency
CAUTION!
Motor continuous current must be maintained at a level below the continuous stall current rating of
the IMA-S actuator or damage to the motor stator will result.
The peak current setting must be maintained at a level below the peak current rating of the IMA-S
actuator or damage to the motor stator will result.
Care should be taken not to exceed the physical travel limits of the IMA-S actuator. Doing so will
cause the actuator to reach mechanical end of stroke internally. Although protected by the end of
stroke bumpers, repeatedly reaching internal end of stroke can physically damage the screw and the
internal components of the actuator.

4: MECHANICAL INSTALLATION OF IMA-S ACTUATORS
4.2 Mounting Considerations
4.2.1 Alignment and Side Loading:
Alignment of the actuator with respect to the application load and axis of motion is essential to
minimize side loading. The IMA-S is not meant to be used in applications where side loading occurs
as side loading will reduce the life of the actuator and rod seals.
4.2.2 Side Load Considerations
The IMA-S integrated motor actuator is not meant to be used in applications where side
loading occurs. Loads must be guided and supported. Loads should be aligned with the
line of motion of the thrust rod. Side loading will affect the life of the actuator.

2. Carefully remove linear actuator from package. *Consider the weight of the actuator.
Depending on the configuration, the actuator can weight up to approximately 22.7 kg (50 lb)
3. Visually inspect the actuator for damage
4. Notify the carrier of any shipping damage immediately
5. If the actuator is mounted in a vertical or inclined (sloping) position, include safety measures
that control the work load in case of a screw failure.
6. Consider anti-rotation of the rod end. The actuator’s thrust rod must be kept from rotating
in order to achieve linear motion. If the application’s tooling and load is free to rotate, order
the IMA-SA model with internal anti-rotation to prevent the rod from rotating.
7. It is recommended to install the actuator with rod-end down or at a downward inclination to
achieve best seal ingress protection.

8. Follow recommendations for actuator orientation and cable routing.
9. Ensure sufficient clearance around the actuator to allow for airflow and cooling.
10. Follow installation mounting considerations and specifications for each mounting
configuration during installation.
CAUTION!
The IMA-S Series actuator weight range is approximately 4.8 to 22.7kg (10.5 to 50lb). Special
care must be taken when lifting this device. The total stroke of actuator configurations can vary,
therefore the actuator total stroke should be reviewed and taken into careful consideration during
commissioning and operation to ensure actuator movement never reaches the end of stroke in
service causing damage to the actuator.
