3.1.7. Motor I/O Check

3.1.7.1. Procedure

1. Before turning on the main circuit breaker, check again to determine if there is any obstacle

inside the machine or on the conveyor.

2. If the area surrounding the machine is clear, turn on the main switch of the machine. At this

time, check if the front and rear emergency switches are released and the front and rear doors

are closed.

Caution

If the power supply and internal of the machine are not

checked before

turning on the main switch, the machine may be damaged or personal

injury may occur. Be sure to check inside and outside of the machine

before turning on the main switch.

3. If the MMI program is loaded, the I/O of the motor must be checked without pressing the

<Ready> switch on the Front OP Panel. Check if the +/- limit sensor and home sensor operate

normally for each motor by sensing the sensors manually. At this time the XY axes can be

moved manually without difficulty.

3.1.8. Communication Interface Between Machines

1. Set the communication interface between the printer and chip mounter by referring to the

following.

 START Input Signal (Cable No.:①(+),②(-))

The input signal is outputted from the next machine and voltage of approximately 20 ~ 22V is

measured at most input signal terminals.

 READY Output Signal (Cable No.:③ , ④)

The output signal is outputted to the previous machine. Generally, at most output signal

terminals, 0Ω is measured when output signal is outputted and ∞Ω is measured when output

signal is not outputted.

 If the I/F connectors of neighboring machines are different, cut the cable and connect it

referring to the following figure.

 Machines manufactured not in accordance with the SMEMA code such as SIMENS, SANYO

and TDK (RX-11), and machines without dual contact interface shall be examined specially.

 Machine interface must be decided. (Select 2-contact method or SMEMA method suitable for

the user’s environment.).

 Select SYS.SETUP menu and lower menu of the conveyor.

 Select ‘Stand Alone’, or SSA Type (2 contacts), or SMEMA in the ‘In (Before) and Out (After)’

combo box of the inline protocol area.

- Stand Alone: The connection is not established between machines. Setup is made during

manual operation.

- SSA Type: The PCB flows only if the contact is connected in the next machine.

- SMEMA: The ready signal is given by the previous machine (24V), and the contact is

connected in the next machine.

 Check if the interface between connected machines operates normally by using the MMI

bypass function. At this time, perform test using at least 3 pieces of PCB.
