Intended Use

The M-227 linear actuator is a laboratory device as defined by DIN EN 61010-1. It is intended to
be used in interior spaces and in an environment which is free of dirt, oil and lubricants.

Based on its design and realization, the M-227 is intended for single-axis positioning, adjusting
and shifting of loads at different velocities. The M-227 is not intended for high duty cycles and
applications in areas in which a failure would present severe risks to human beings or the
environment.

The intended use of the M-227 is only possible when completely mounted and connected and
only in conjunction with suitable electronics (p. 10) that provide the required operating
voltages. To ensure proper performance of the servo-control system, the electronics must also
be able to read out and process the signals from the rotary encoder.

The M-227 may only be started up, operated, maintained and cleaned by authorized and
qualified staff.

Startup and Operation

General Notes on Startup and Operation

NOTICE

CAUTION

Risk of crushing!

Risk of minor injuries or damage to equipment from crushing between the pusher and a fixed
part or obstacle.

 Use protective structures to keep limbs away from areas in which they could be seized by

moving parts.

 Maintain safety distances according to DIN EN ISO 13857.
 Mount the M-227 so that the motion of the pusher is not hindered by objects in the

workspace.

Collision with the hard stop or an obstacle!

Collision with the hard stop or an obstacle leads to damage or considerable wear on the
M-227.

 Do not place any objects in areas where they can get caught by moving parts.
 If the pusher or the load mounted on it collides with an obstacle, switch off the motor.
 Only command target positions that are located within the travel range.
 Use external limit switches to avoid collisions.
 Stop the motion immediately if a controller malfunction occurs.
 Ensure that the M-227 does neither abruptly stop at the end of the travel range nor

attempt to continue moving.

 Ensure that the end of the travel range is approached at low velocity.
 Determine the maximum velocity for your application.

NOTICE

Unintentional motion!

Unintentional motion of the M-227 is possible when connecting it to the controller.

 Before connecting the M-227, check whether a macro is defined as the startup macro in

the controller and cancel the selection if necessary.

INFORMATION

Unsuitable settings made to the servo control parameters can impair the performance of the
M-227. The consequences of this can be expressed as follows:

 Oscillation
 Imprecise approach of the position
 Settling time is too long

 If the performance of the M-227 is not satisfactory, check the settings for the servo control

parameters of your controller.

 Use the default parameters for the first startup only.

INFORMATION

Due to its compact design, the M-227 does not have internal limit switches. Without limit
switches, the M-227 must be stopped manually to avoid collision with the hard stop.
Therefore, we strongly recommend using external limit switches. Note that all PI motor
controllers support limit switches.

INFORMATION

If the programmed velocity is too high, accelerating and decelerating ramps will not be
performed as programmed, and the physical velocity will be lower than the profile velocity.
When this happens the trajectory generator may have already completed its move while the
actuator is still trying to catch up.

Operating Parameters

If you use the software from the scope of delivery of the electronics (p. 10), the operating
parameters can be loaded from the positioner database. The records in the positioner database
are updated regularly.

 Install the PI Update Finder from the product CD for the electronics onto your PC and

update the positioner database on your PC.

Further information can be found in the user manual for the electronics (p. 10).

INFORMATION

Frequent motion over a limited travel range can cause the lubricant to be distributed unevenly
on the drive screw.

 Perform a maintenance run over the entire travel range at regular intervals (see user

manual for the controller). The more motion is done over a limited travel range, the
shorter the time must be between the maintenance runs.

 You have read and understood the “General Notes on Troubleshooting” (p. 17).

Tools and accessories

 1.2 mm hex key

Unblocking the actuator by hand

1. Remove the set screw located about in the middle of the motor housing (p. 9). This
screw clamps the motor/gearhead assembly inside the housing.

2. Hold the M-227 with both hands and turn the motor housing CCW relative to the
micrometer housing (p. 9) until it breaks loose. Look for the small hole (Ø 2.5 mm) in
the motor housing near the edge to the micrometer housing. This hole allows access to
two set screws which clamp the bellows coupling to the spindle. Turn the motor
housing CCW until you see the first set screw through the hole and untighten it.

3. Turn the motor housing until you see the second set screw and untighten it.

4. Turn the motor housing CCW until you can pull it off the micrometer housing.
Important note: To prevent damage, avoid bending and pull forces on the bellows
coupling.

5. Turn the spindle CW or CCW in order to unblock the jammed spindle.

6. Reassemble the M-227.

Coupling of the Actuator Slips

Retightening the Coupling

The metal bellows coupling is clamped by two small radial set screws to the spindle. In the rare
case that the coupling slips, these two screws need to be retightened. To do this, the M-227
must be disassembled.

Requirements

 You have disconnected the M-227 from the electronics.
 You have read and understood the “General Notes on Troubleshooting” (p. 17).

Tools and accessories

 1.2 mm hex key

Retightening the coupling

1. Remove the set screw located about in the middle of the motor housing (p. 9) fixing the
motor/gearhead assembly.

2. Turn the motor/gearhead assembly together with the cable until one of the radial set
screws clamping the coupling bellows can be seen through the hole near the transition
from the motor housing to the micrometer housing (p. 9) of the M-227.

3. Untighten the set screw.

4. Turn the motor/gearhead assembly until the second set screw appears beneath the
hole. Untighten this set screw as well.

5. Now the motor/gearhead assembly can be pulled out of the motor housing.
Important note: To prevent damage, avoid bending and pull forces on the bellows
coupling.

6. Examine the connection of the coupling bellows with the gear shaft and tighten both
fixing screws.

7. Reassemble the M-227.
