7.1 Mechanical Interface

7.1.1 PWB conveyor height

900 ± 20 mm

950 ± 20 mm (option)

7.2 Electrical Interface

7.2.1 Types and meanings of electric signals

The concept of electric signal connections between this system and the opposite machine is

shown in “Figure 12 Conceptual diagram of electric signal connections.” In Figure 12, the electric

signals of ① and ② between this system and the upper-side equipment and the electric signals of

③ and ④ between this system and the lower-side equipment are shown below.

a) The electric signal ① is called carry-out request input signal (or board available IN)and

receives a PWB carry-out request from the upper equipment.

b) The electric signal ② is called carry-out enable output signal (or ready OUT) and causes the

upper-side equipment to carry out a PWB.

c) The electric signal ③ is called carry-out request output signal (or board available OUT) and

asks the lower-side equipment to carry out a PWB.

d) The electric signal ④ is called carry-out enable input signal (or ready IN) and receives PWB

carry-out permission from the lower-side equipment.

8 Safety Specifications

8.1 Standard Specifications

8.1.1 Emergency stop

An emergency stop is performed by emergency stop button. When the emergency stop switch is

pressed, each axis is stopped immediately and the driving power supply of the servo motor is shut

off.

8.1.2 Safety cover

A cover is provided on the front side of the machine. The open/close status is detected by cover

open switch. When the cover is opened, the continuous operation is temporarily stopped. With the

safety cover open, the machine cannot be operated.

8.2 CE mark Specification

The CE mark specification is not available.

9 Maintenance Specifications

9.1 Troubleshooting

The improved help function can find out an abnormal status caused by any factor and a

recovering method to return to the normal status.
