The following page appears

• Set 1 Volt, on the ANALOG OUTPUT parameter
• Presse the key (Analog output +1 Volt), check that the value of the ENCODER parameter increases (if it decreases, the two phases of the encoder in the CN9 connector must be reversed).
• A - A' = Longest possible space
• Mark the starting position (A)
• Reset the ENCODER value:
• Execute the movement from A to A'
• Write on the PULSE parameter, the value showed in the ENCODER parameter
• Measure the delta space A - A'
• Write the delta space value A - A' on the MEASURE parameter
• verify the value that appears in the VEL parameter, when you press the key
• The maximum speed value of the conveyor will be 10 times larger than the VEL showed. this value should be written to the MP-08 parameter

Important:

• The PULSE value must always be greater than the value of MEASURE (the optimal value is “MEASURE x 10 = PULSE”)
• Introduce the MEASURE value into the unit of measure that you choosen. Example: if you choose 1/10mm unit of measure and the delta space measure is 133.5mm, introduce the value 1335 into the MEASURE parameter
• The Pulse and Measure parameters inserted here, will be automatically transcribed into the GP-01 and GP-02 parameters

The motor start sequence can be executed in 3 modes (parameter MP-05)

1 = enable on J1-P20. N.B.Motor start outputs are in common with head descent outputs.
2 = enable on the RMC module.
3 = enable on the RMC module. N.B. It is activated automatically at the entrance of the piece in the machine.

The motor start sequence uses the same outputs used for the head descent.

Input I2 determines whether the outputs are used for the descent control of the Heads or if they are used for starting motors.
Input I3 starts the motor sequence.

Below is the diagram of how the motor start sequence works with the MP-05 = 1 parameter.

Legenda

• I2 = Head activation (OFF) / Motors start (ON)
• I3 = Motors start
• O17 = Head activation (OFF) / Motors start (ON)
• O1÷O16 = Heads command 1÷16
• O18 = End of start-up

1. The input I2 is activated and then the instrument changes the mode of operation from activating motor start heads. All head-related outputs (O1÷O16) are disabled.
2. After the t3 time (time passage operation heads descent / motors start) the instrument activate the O17 output and enable the start motors operation.
3. When activating the I3 input you have the beginning of the procedure of cascading motors and you activate the output relative to the first set-up-enabled head in ascending order.
4. After the t1 time (time interval motors start) you have the output activation for the next head enabled in set-up.
5. In the event that a start motor command is activated again (I3) is not processed. A new start command will only be processed in case the instrument first goes into operation activation heads (O17 = OFF) and then come back in start motors operation mode (O17 = ON).
6. The output of the last enabled head is activated and the start motors procedure is completed.
7. The O18 output is activated after the t2 time (The time between the start-up of the last motor and the activation of the end-of-motor output O18).
8. Turn off the I2 input and the instrument changes the way of operation from starting motors to head starting. All head-related outputs (O1÷O16) and the O18 outputs are deactivated.
9. After the t4 time (start-activation step time) the instrument turns off the O17 output and enables the heads activation operation mode.

The motor start sequence uses the outputs in the RMC module.

I2 input has no operation.
Input I3 starts the motor start sequence.

Below is the diagram of how the motor start sequence works with the MP-05=2.

Legenda

• I3 = Motors start
• O25÷O44 = Heads command 1÷20
• O18 = End of start-up

1. When activating the I3 input you have the beginning of the procedure of cascading motors 3. and you activate the output relative to the first set-up-enabled head in ascending order.
2. After the t1 time (time interval motors start) you have the output activation for the next head enabled in set-up.
3. In the event that a start motor command is activated again (I3) 5. is not processed.
4. The output of the last enabled head is activated and the start motors procedure is completed.
5. The O18 output is activated after the t2 time (The time between the start-up of the last motor and the activation of the end-of-motor output O18).

The motor start sequence uses the outputs in the RMC module.

I2 input has no operation.
Input I3 starts the motor start sequence.

The “motor start” sequence is started automatically as soon as the first piece “enters” the machine. N.B. When the last worked piece “comes out” of the machine, the motor start outputs are deactivated.

Below is the diagram of how the motor start sequence works with the MP-05=3.

Legenda

• I9 = Piece acquisition
• O25÷O44 = Heads commad 1÷20
• O18 = End of start-up

1. When activating the I9 3. input you have the beginning of the procedure of cascading motors and you activate the output relative to the first set-up-enabled head in ascending order.
2. After the t1 time (4. time interval motors start) you have the output activation for the next head enabled in set-up.
3. The output of the last enabled head is activated and the start motors procedure is completed.
4. The O18 output is activated after the t2 time (The time between the start-up of the last motor and the activation of the end-of-motor output O18).
