Overview Operational Safety
447 Student Guide SIPLACE X-Serie and X4I SW70x (AL2)
The two protective doors are each equipped with a protective door switch. These are looped into the
starting circuit of the respective monitoring device.
If the EMERGENCY STOP button is pressed during operation or one of the two protective doors opens,
the relevant safety combination is tripped and the drives are locked via contactors on the electronics
board.
The signaling circuit for the protective door monitoring system is transmitted to the MTC2 controller by
the relevant safety combinations, via normally open contacts.

13.2 Construction and mode of operation
The MTC2 extends the capacity of a SIPLACE station to supply components by up to 100 JEDEC waffle
pack trays. It has its own controller (C167 controller board) and is integrated into the station computer
software. The setup of the MTC2 is integrated into the line controller software of a system.

Construction and mode of operation Lifting and Feeder Motors
449 Student Guide SIPLACE X-Serie and X4I SW70x (AL2)
Each of the two MTC2 towers has a lifting axis and a feed axis. The lifting axes can be set up with a large
number of waffle pack trays in cassettes and transport these vertically. The feed axes transport waffle
pack trays which have been set up horizontally to the transfer position to the SIPLACE station.
All drive units comprise Masterdrive drive systems:
▪ The servo motors of the lifting axes each drive a spindle via a dual toothed belt, which transports
vertically the cassettes which have been set up. A holding brake in the motors, which is controlled
by the Masterdrive via optocouplers, prevents the axis from moving when the machine is switched
off. The lifting axes remain under control when a position has been reached. The toothed belts are
duplicated for safety reasons and are monitored using inductive sensors.
▪ The servo motors of the feed axes use a toothed belt and belt gear to move a driver, which then
moves the selected WTC horizontally to the transfer position of the SIPLACE station.
Lifting axis
One revolution of the servo motor is equivalent to 4096 pulses or a lift of 10 mm on the spindle.
Feed axis
One revolution on the servo motor is equivalent to 4096 pulses or 27.78 mm on the linear guide.

NOTICE
Same motor types for lifting and feeder motors!
Both lifting axis motors and the two feeder axis motors must be of the same type:
MTC2 version 01 [03011837-01]: Motor type 1 FK6 [00354906-01]
MTC2 version 02 [03011837-02]: Motor type 1 FK7 [03035813-01]
