Table 2-12: Signals from IMM (EM67)
Contact No. Function
ZA1
ZC1
Emergency stop channel 1
The emergency stop switch of the injection moulding machine is used to interrupt
the emergency stop circuit of the robot.
ZA2
ZC2
Emergency stop channel 2
The emergency stop switch of the injection moulding machine is used to interrupt
the emergency stop circuit of the robot.
ZA3
ZC3
Safety devices of machine channel 1
For protecting against hazardous motions of the robot. The switch is closed when
the safety devices of the injection moulding machine is active.
ZA4
ZC4
Safety devices of machine channel 2
For protecting against hazardous motions of the robot. The switch is closed when
the safety devices of the injection moulding machine is active.
ZA5
Optional
Reject
HIGH signal when the moulding is a reject. HIGH signal when the mould is open
and must remain HIGH until
“ Enable mould closure ” (see pin contact No.A6).
ZA6
mould closed
HIGH signal when the mould closing is completed, the signal “ Enable mould
closure ” is no longer required (see pin contact No.A6).
ZA7
mould open position
HIGH signal when the mould opening position is equal or more than the required
position. Inadvertent alteration to mould opening stroke smaller than that required
for the handling robot approach must be impossible.
ZA8
Optional
Intermediate mould opening position
HIGH signal when mould opening reaches a set position than mould opening
position. The signal remains HIGH to the end of mould opening position. Two
sequences are possible with this signal:
1) mould opening stops on intermediate position and gives start signal to robot.
mould opening restarts with the signal
“ Enable full mould opening ” (see pin A7).
2) mould opening does not stop on intermediate position, however gives the signal
to robot. At this sequence the signals
“ Enable full mould opening ” (see pin A7)
Low signal when intermediate mould opening position is not in use.
ZA9
Supply from robot
24 V DC (Reference potential)
ZB2
Enable operation with robot (Automatic)
HIGH signal when the IMM is able to operated with robot.
ZB3
Ejector back position
HIGH signal when the ejector has been finally retracted regardless of the moving
platen position.The signal is the acknowledgement for the
” Enable ejector
retraction ” signal (see pin contact No.B3) when the ejector sequence is selected.
