4.2 Function

The axis converts the rotary motion of the mounted motor into a linear motion of the slide. The screw drive converts the torque of the motor into a feed force. The linear movement of the slide is precisely guided by the guide. Sensors enable the monitoring of end positions, reference position and intermediate position.

5 Transport

WARNING

Risk of injury due to falling product

If the product is lifted incorrectly, it may fall and cut, crush or separate body parts.

7 Commissioning

WARNING

Risk of injury due to unexpected movement of components.

• Protect the positioning range from unwanted intervention.
• Keep foreign objects out of the positioning range.
• Perform commissioning with low dynamic response.

i

Block-shaped acceleration profiles without jerk limitation can have the following effects:

• High mechanical loads on the lead screw due to high force peaks.
• Overshooting effects during positioning.
• Rise of the entire system.

Recommendation: reduce high force peaks in the acceleration and deceleration phases by using the jerk limitation.

i

Identical axes can generate different running noises depending on the parameterisation, mode of operation, type of mounting, installation environment and components.

i

For use with reduced particle emission:

- Clean product 8.3 Cleaning axis.

Requirements:

• The motor encoder is referenced to the reference mark by a homing run.
• The motor encoder has the absolute reference to the reference mark.
• The direction of movement of the slide is determined by the direction of rotation of the motor.
• The mounting of the drive system has been checked.
• The installation on the motor has been checked.
• There are no foreign objects within the range of motion of the drive system.
  –Maximum permissible feed force and drive torque as a function of acceleration, deceleration, e.g. with stop function or quick stop, speed, moving mass and mounting position, are not exceeded.
• Axis is not mechanically overloaded and dynamic setpoint deviation is not exceeded as a result of force peaks, torque peaks or overshoot effects, e.g. overrunning the end position.
  Overloads and overruns as a result of jerk limitation must be restricted by reduced acceleration and deceleration setpoints or optimised controller settings.
• The software end positions are not within the effective range of the mechanical stops.

• No homing or test run to mechanical end stops.

• Start check run.

• Select permissible reference points "against reference switch" for the homing.
• Start the homing run with reduced speed setpoints, acceleration setpoints and deceleration setpoints.
• Start the test run with reduced speed setpoints, acceleration setpoints and deceleration setpoints.
• Check that the slide completes the entire travel cycle within the specified time.

The slide stops its travel when it reaches a limit switch and the drive system is ready for operation.

8 Maintenance

8.1 Safety

WARNING

Unexpected movement of components.

Injury due to impacts or crushing.

- Before working on the product, switch off the control and secure it to prevent it from being switched back on accidentally.

8.2 Check reversing backlash

- Check the reversing backlash (reversal error) of the slide at every maintenance interval, e.g. lubrication interval. If the maximum permissible reversing backlash is exceeded, replace the axis.

Max. permissible reversing backlash	[mm] 0.15

8.3 Cleaning axis

• If the guide rail is dirty, clean it with a clean, soft and lint-free cloth without cleaning agents and then apply the lubricant thinly to the guide rail.
• Clean the other product components with a clean, soft cloth and non-abrasive cleaning agents.
  For use with reduced particle emission:

- Remove abraded particles and dirt from the product:

– Prior to initial commissioning.

- Regularly during operation.

8.4 Lubricating axis

Requirements:

-The pressure grease gun LUB-1, 647958, is available.

- The roller bearing grease LUB-KC1, 684474, Elkalub VP 922, is available.

- The lubrication adapter, axial output, LUB-1-KE, 744167, is available.

1. Calculate the load comparison factor f_v with the formula for combined loads 10.1 Technical data, mechanical.

Maintenance

1. Take the lubrication interval S_int as a function of the load comparison factor f_v from the characteristic curve.

1. Determine the load factors:

-Dusty and dirty environment.

-Nominal stroke < 300 mm or > 2000 mm.

-Ambient temperature > +40 °C.

- Service age > 3 years.

- The travel profile matches triangular operation, e.g. frequent acceleration and braking.

1. If there is a load factor, halve the lubrication interval S_int . If there are multiple load factors, reduce the lubrication interval S_int to a quarter of the standard interval.

2. If necessary, replace the needle point of the pressure grease gun with the lubrication adapter with axial or radial outlet.

3. Press the pressure grease gun onto the lubrication nipple for the ball screw. Press in the roller bearing grease at the rear.
