Safety
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.

Safety Precautions
Mechanical Dangers
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.
NOTICE
Damage due to excessive torque on the pusher!
Excessive torque on the pusher (e.g., when the tip is replaced) can damage the M-227.
Do not exceed a torque of 1 Nm on the pusher.
NOTICE
Increased friction from lateral forces on the pusher!
Lateral forces acting on the pusher impair the motion of the pusher and increase wear on the
drive components.
Avoid lateral forces on the pusher of the M-227.
NOTICE
Damage from wrong clamping or clamping too tightly!
Wrong clamping or clamping too tightly can damage the M-227.
Do not clamp the M-227 on the motor housing (p. 9).
Do not clamp the M-227 too tightly.
NOTICE
Cable break due to excessively bent or crushed cable!
A cable break leads to failure of the M-227.
Install the M-227 so that the cable cannot be bent too strongly or crushed during
operation.

Electrical Dangers
NOTICE
Operating voltage too high or incorrectly connected!
Operating voltages that are too high or incorrectly connected can cause damage to the M-227.
Only operate the M-227 with electronics and original accessories from PI.
Do not exceed the operating voltage range (p. 21) for which the M-227 is specified.
Operate the M-227 only when the operating voltage is properly connected; see "Pin
Assignment" (p. 25).
Thermal Dangers
CAUTION
Risk of burning!
The M-227 can overheat in continuous operation with high load. Touching an overheated
M-227 can cause slight injuries from burning. In addition, overheating can damage the M-227.
To prevent overheating, do not operate the M-227 continuously with high load.
If overheated accidentally:
Do not touch the M-227 until it has cooled off.
