Note that the cables required for connecting the M-238 to the electronics must be ordered separately. -
Page 11: Technical Features
3.5.2 Encoder The M-238.5PG model is equipped with a rotary encoder. A rotary encoder is implemented at a rotating point in the drivetrain, e.g., the motor shaft. The encoder provides a certain number of signals for each change of position. The controller counts the encoder signals, the so-called pulses, in order to determine the relative position. -
Page 13: Unpacking
4 Unpacking Unpacking 1. Unpack the M-238 with care. 2. Compare the contents with the items listed in the contract and the packing list. 3. Inspect the contents for signs of damage. If there is any sign of damage or missing parts, contact PI immediately. -
Page 15: Installing
The cable will break from excessive bending or crushing. A broken cable will lead to failure of the M-238 or damage to the actuator or the electronics. Install the M-238 so that the cable cannot be bent or crushed too strongly. NOTICE... -
Page 16: Providing A Suitable Mechanical Mounting And Installation Environment
In accordance with the legal regulations, avoid or label danger areas resulting from the installation of the actuator and from use (e.g., risk of crushing in the case of heavy moving loads, fast actuator motion and/or high drive torques). Version: 1.1.0 MP77E M-238 High-Load Linear Actuator... -
Page 17: Installing The M-238 Into A Mechanical Mounting
5 Installing Installing the M-238 into a Mechanical Mounting INFORMATION To achieve an optimal repeatability, the mounting shaft must not have any backlash. When assembling, make sure that the actuator and the mechanical mounting have been connected perfectly. We recommend installing the actuator into the mounting with a clamp connection. The following instructions refer to this case. -
Page 18: Connecting The M-238
Connect the M-238's drive plug to the drive socket on the electronics. b) Secure the connectors against unintentional removal. 3. Connect the power adapter: a) Connect the power cord to the M-238's power connector with the help of the power adapter. b) Connect the power cord to the power adapter. -
Page 19: Starting
Damage due to the pusher hitting the hard stop! When the limit switches are deactivated, the motion of the pusher is stopped by the hard stop and the M-238 could be damaged. Do not deactivate the limit switches in the software. -

3. Configure the electronics for the M-238 during startup: − If you are using a digital controller from PI: In the PC software, select the entry in the positioner database that matches the M-238 model exactly. If you are using electronics from another manufacturer: Configure the electronics −... -
Page 21: Maintenance
The maintenance run serves the purpose of distributing the existing lubricant. If the M-238 is moved continuously over a short travel range (<20 % of the entire travel range) in an industrial situation, do a run across the entire travel range approximately every 2000 motion cycles. -
