Description

The MICRODRIVE 3 drive is an electrically driven motor that is responsible for moving the end product in a linear direction. This adjustment is created by the in and out movement of a stroke pipe. The MICRODRIVE 3 drive is controlled using an Okin handset.
The technical specifications for the variants are listed in Chapter 4 “Technical Specifications”. The variants differ according to their:

• Working performance,
• Speed,
• Pushing and pulling forces,
• Dimensions and stroke,
• Clevises (stroke pipe, gear)
• Mount for the stroke pipe (refer to section 3.1.2),
• Connection variants (refer to section 3.1.3).

Components

• A Head-of-stroke pipe
• B Electrical connection
• C Motor
• E Guidance profile
• D Gear clevis

Stroke pipe head variants

• A Stroke pipe head with slot / with hole
• B Stroke pipe head without slot / with a hole
• C Stroke pipe head (metal)
• E Stroke pipe head with hole
• G Stroke pipe head with slot / with hole (metal)
• D Stroke pipe with reduced end
• F Stroke pipe with hole (optional distance

Attachment of the stroke pipe
There are two types of stroke pipes available for different types of applications. The stroke pipe can be screwed onto the spindle screw or it can be mounted unattached. The drive only exerts pushing force when the stroke pipe is mounted loosely (unattached). The motions of the drives for these two versions are shown in the following illustrations.

• If the stroke pipe is unattached, then the end product can be designed to prevent the stroke pipe from coming out during operations. This can be accomplished by implementing a fixed end-stop mechanism (refer to the “Safety notices to observe during installation” in the “Installation” chapter).

Installation

Safety notices to observe during installation
Basic safety rules must be followed to ensure that the end product can be continually oper-ated safely. The following rules must be observed while using the end product and while installing the drive.

Avoiding fatigue fractures

• Install the drive in the end product so that it is properly aligned. This will help prevent shear stress.
• Do not position the drive at a slanted angle when installing it in the end product. A slanted angle between the intended direction of movement of the end product and the drive’s direction will create shear stress and could lead to a fatigue fracture.
• Be sure to install the drive so that it can always move freely in all operative states.
• You should never screw the stroke pipe into the drive.

Avoiding an overrun of the stop point with the end product

• Your end product should contain mechanical end stops. These will limit the drive movement and significantly increase operational safety. DewertOkin recommends that you build such mechanical end stops into your end product.

Make sure that your operating instructions inform the user of these safety points.

Installation procedure

NOTICE: Carry out the assembly of the drive when the application is in a no-load position.

• In its final position, the drive must be either fully retracted or extended.
• Damage to the drive is prevented only in in no-load position and a safe assembly is ensured.

An installation example

• A Safety clip
• B Bracket for securing the drive (on the stroke pipe side)
• C Head of stroke pipe
• E Gear clevis
• D Mounting bolt
• F Bracket for securing the drive (on the motor side)

In the following example, the installation of the MICRODRIVE 3 drive into the end product is shown using the mounting bolt.

Certain details may change because of technical changes.

1. Move your product into a position where it is supporting no load.

2. Push the drive’s gear clevis (E) onto the bracket (F).

3. Insert the mounting bolt (D) into the bracket (F).

4. Secure the mounting bolt (D) with the safety clip (A).
   Option 1 Option 2 NOTICE: You should never screw the stroke pipe into the drive. A stroke pipe that has been screwed into the drive can result in fatigue fractures.

5. If the stroke pipe clevis (C) does not align exactly with the gear clevis (E), the stroke pipe may be unscrewed out of the drive by no more than a half-turn.
   NOTICE: The stroke pipe may only be turned one-half rotation out of the drive. Do not rotate the stroke pipe further out. An over-rotation can lead to unsafe operations.

6. Attach the stroke pipe (C) using a mounting bolt (D) to the fitting (B).

7. Secure the mounting bolt (D) with the safety clip (A).

8. You may now connect the drive’s electrical connection (refer to section 5.2.2).

Electrical connection

CAUTION: Danger of pinching/crushing injuries!
The electrical components may be connected or disconnected only when the mains power and the battery plug (when present) are disconnected. This ensures that uncontrolled movements cannot be triggered.

• If the hand switch will be used to control two drives, you must first connect both drives electronically to each other (for example, over a control unit or double drive). Then you can connect the handset.

Routing the electrical cables
When routing the cables, be sure that:

• the cables cannot get jammed,
• no mechanical load (such as pulling, pushing, or bending) will be put on the cables, or
• the cables cannot be damaged in any way.

Fasten all cables (especially the mains cable) to the end product using sufficient strain relief and kink prevention methods. Be sure that the design of the end product prevents the main cable from coming into contact with the floor during transport.

Dismantling

CAUTION: Danger of pinching/crushing injuries!

• The electrical components may be connected or disconnected only when the mains power and the battery plug (when present) are disconnected. This ensures that uncontrolled movements cannot be triggered.
• Be sure to carry out work on the drive in a position so that no loads are bearing on it. Only in this way can you be sure to avoid any risks of crushing or injury.

1. Move your product into a position where it is supporting no load.
2. If multiple drives are connected electrically, they should be disconnected from each other.
3. Remove the security clips and the mounting bolt.

Notes on operation

These installation instructions do not contain all the information required for the safe operation of the end product. They only describe the installation and operation of the drive as components (as de-fined in the Machinery Directive as a “partially assembled piece of machinery”).

Power-on time / intermittent operations

NOTICE

• The MICRODRIVE 3 drive has been designed for intermittent operations. Intermittent operation is an operational mode where the drive must pause after a specified maximum period of opera-tion (power-on time). The drive can overheat when these pauses are not maintained.
• The MICRODRIVE 3 drive must operate with an intermittent duty of 1 min. ON / 8 min. OFF. This means that after the unit is operated with its rated load for up to one minute it must then be paused for 8 minutes.

Shutting off the drive
To shut off the drive, unplug the mains power plug and the battery plug (when present)! The power plug must always be accessible during operations so that emergency shut-off is possible.

Avoiding cable damage
Be sure that your operating instructions inform the user about the possible cable risks.

NOTICE: The cables (in particular the electrical connection for the drive and the power supply cable for the drive system) must not be squashed or crushed. To prevent damage to the drive, no mechanical strain should be placed on the cables.

Maintenance and cleaning

Maintenance
The MICRODRIVE 3 drive does not require maintenance.

Cleaning
Clean the MICRODRIVE 3 drive as needed using a dry, antistatic cloth.

NOTICE

• Always disconnect the mains power plug from the drive system (and the battery plug if present) before you start to clean the unit!
• Never clean the drive in an automated washing system or with a high-pressure cleaner. Do not allow fluids to penetrate the drive. Damage to the system could result.
• Do not use a cleanser that contains benzene, alcohol, or similar solvents.
• Make sure that you do not damage the drive’s connecting cable.
