2. Cause and Remedy of Tape Feeder Installation

Error (Lifted Feeder)

Whenever a feeder installation error (lifted feeder) is detected, the machine

stops instantaneously in an error condition and an error message is issued re-

gardless of machine operation mode (“RUN”, “PAUSE”, or “STOP”) except

for the time when a feeder is replaced with the supply cover being opened

because machine protection has top priority.

Fig. 1.1

Cause of Feeder Installation Error (Lifted Feeder)

• The tape feeder is not seated correctly.

• The suppressor of the tape feeder is disengaged and kept afloat (lifted).

• A component has popped out from the tape feeder or the vibratory stick

feeder and is shielding the lifted feeder detection sensor.

• A vertical component is picked up because the pick-up position has deviated

from the correct one or the tape is not fed normally and the picked compo-

nent is shielding the sensor at the position where the head has ascended.

• The foreign substance was detected.

• The amount of slack of the tape is large.

Remedy

(1) Press the [RESET] button to cancel the error condition.

(2) Press the [READY] button on the side where the lifted feeder was de-

tected to unlock the supply cover.

(3) Open the supply cover and remove the cause of the lifted feeder detec-

tion.

(4) Confirm that the light is emitted and received by the lifted feeder detec-

tion sensor.

(Confirm that the indicator lamp of the sensor is “ON”.)

(5) Close the supply cover and press the [READY] button to lock the cover.

(6) Press the [ZERO] button to zero each device.

(7) After all devices are zeroed completely, press the [START] button to re-

start the operation.
