1. – SignalsTo get a change of positions on the BSV-N turrets, the con-trol equipment (usually a N.C. equipment) must control the components mentioned below according to a well defined sequence (see wiring diagram on page 15).• Motor (1)• Brake (3)• Indexing solenoid (4)The following output signals from the turret are provided for driving the positioning cycle:– Angular position given by the angular position transmitter (7)– Indexing control switch (5)– Locking control switch (6).
1. – Description of the operating sequenceThis description refers to sequence cycle: the first part gives the sequence to pass from position 1 to position 2 with clockwise rotation, the second part gives the sequence to pass from position 2 to position 12 with counterclockwise rotation.As indicated by the cycle, the controls are to be performed according with the following sequence:
• De-energize the brake (3) and start motor rotation in the desired direction.• If, as in the case shown by the diagram, the next position (pos. 2) is the Stop position, when the strobe signal reached a zero level, the solenoid (4) is to be energized.In case of passage from position 2 to position 12, wait for the reading signaling the passage on pos. 1 then, since the next one is the Stop position, wait until the next strobe signal reaches a zero level and (at that time only) energize the solenoid (4).N.B.: The maximum lag time between the reading of the strobe signal and the excitation of the solenoid (4) cannot exceed the R1 values indicated in the table.• The turret goes on rotating until the indexing pin, pushed by the solenoid (4), enters into the mechanical stop slot.This movement is detected by the sensor (5) which must immediately stop the motor that, once expired the T1 time will re-start rotating in the opposite direction.• During this phase the turret is locking and its locked position is detected by the sensor (6) and this signal is used to stop the motor (1). The maximum lag time between the signal of the sensor and the stopping of the motor must never exceed the R2 value shown in the table. At this point the machine can be started, in order to go on working.• The solenoid (4) is to be de-energized after the expiration of the T2 lag time starting from the moment when the sensor (6) signal is read.
N.B.: The T1, T2, R1, R2 times must be understood as real times execution of the controls and the signals checked on the terminal board of the turret.For an accurate detection and measurement of the above mentioned values it is advisable to use adeguate instru-mentation such as an oscilloscope with memory and current sensing devices.
