DANGER
The following activities require access to machine parts that are moved or carry dangerous
voltage. Only perform the activity that is described and do not touch any other live or moving parts.
There is a risk of death, severe injury and/or considerable damage to equipment even if only one
of these instructions is not followed.
Remove the left cover in front of the electronics board and the covers on the right and the left
in front of the Masterdrives (see Fig. 3.4 - 1).
Switch the motor protection switch off (see Fig. 3.4 - 2).
To relieve the tension the toothed belts, loosen the brake on the servo motor in the following
way to rest the lifting axis on the buffer:
Check that the MTC 2 has been switched off and is isolated from the power supply.
Remove the connector for external signals from the Masterdrive for the lifting axis (see Fig.
4.1 - 1, item 2).
Move the cable from Pin 3 to Pin 1.
Attach the connector.
Connect the MTC 2 to the power supply and switch it on.
The lifting axis audibly moves a distance of a few mm up to the buffer.
Check that the lifting axis is actually at its end position.
Reconnect the cable as it was originally in the following way:
Switch off the MTC 2 and isolate it from the power supply.
Remove the connector for external signals from the Masterdrive for the lifting axis (see Fig.
4.1 - 1, item 2).
Move the cable from Pin 1 to Pin 3.
Attach the connector.
Switch the motor protection switch on.
Attach the covers.
Undock the MTC 2 from the SIPLACE station (see User Manual).
Crank up the MTC 2 in a clockwise direction until it stops.
