Refer to “3.4. How to order”
Note 1) The weight changes by the selected suction cup. Refer to “3.4 How to order”.
Note 2) Limited by the cup diameter, mounting orientation or workpiece. The weight of the workpiece shall be maximum
workload or less.
Gripping or transfer of workload exceeding the maximum workload leads to the decrease of vacuum due to air leakage.
Note 3) Impact resistance: The characteristics are satisfied after tested one time in each of the X, Y and Z directions without
energization. (Initial value)
Vibration resistance: The characteristics are satisfied after tested a one sweep in each of the X, Y and Z directions at 10
to 500 Hz without energization. (Initial value)
Note 4) Values at the standard supply pressure. Values are based on standard of SMC measurements. They depend on
atmospheric pressure (weather, altitude, etc.) and measurement method.
Note 5) This shows the pressure just before the supply (P) port.
The performance such as vacuum pressure may reduce, depending on supply air capacity, the piping volume (piping
length and diameter) and affection of air consumption of other devices which operate at the same time.

3.2. Flow rate / Exhaust characteristics
■Flow rate / Exhaust characteristics.
The flow rate characteristics correspond to the standard supply pressure (0.5MPa).
* The actual suction flow at the point of suction varies depending on the piping conditions to the vacuum port.
■How to read the flow rate characteristics Graph
Flow rate characteristics are expressed in ejector vacuum pressure and suction flow. If suction flow changes,
the vacuum pressure will also be changed. Normally this relationship is expressed in ejector standard
operating pressure use. In the graph, Pmax is maximum vacuum pressure and Qmax is maximum suction
flow. The values are specified according to catalog use. Changes in vacuum pressure are expressed in the
below order.
1. When the ejector suction port is covered and made airtight, the suction flow becomes zero and vacuum
pressure is at the maximum value (Pmax).
2. When the suction port is opened gradually, air can flow through, (air leakage), suction flow increases, but
vacuum pressure decreases. (condition P1 and Q1)
3. When the suction port is opened further and fully opened, suction flow moves to the maximum value
(Qmax), but vacuum pressure is near zero (atmospheric pressure).
As described above, the vacuum pressure changes when the suction flow changes. In other words, when
there is no leakage from the vacuum port, the vacuum pressure can reach its maximum, but as the
amount of leakage increases, the vacuum pressure decreases. When the amount of leakage and the
maximum suction flow become equal, the vacuum pressure becomes almost zero.
In the case when a ventilative or leaky workpiece should be gripped, take note that vacuum pressure will
not rise.

3.3. How to calculate theoretical lifting force
This manual shows how to calculate theoretical lifting force only. Refer to the catalog of suction cupsfor further
detail of suction cup selection method.
■How to calculate theoretical lifting force
The theoretical lifting force of a cup can be found by calculation or from the theoretical lifting force table.
Calculation
Theoretical lifting force table
The theoretical lifting force (not including the safety factor) can be determined by the cup diameter and vacuum
pressure.
The required lifting force can then be determined by dividing the theoretical lifting force by the safety factor t.
Lifting force = Theoretical lifting force / t
Theoretical lifting force (Theoretical lifting force = P x S x 0.1)

Program setting
Operation program can be set from the “Program” tab.
(1)：“Select operation”
3 types of operation NODEs are available.
1：“ADSORB ONLY NODE” starts adsorption. This does not monitor the pressure sensor signal.
2：“ADSORB AND CHECK VACUUM LEVEL NODE” starts adsorption. In this case, after checking the
pressure sensor signal and confirming the adsorption, the transition of the operation occurs.
3：“RELEASE ONLY NODE” starts vacuum release. This does not monitor the pressure sensor signal.
(2)：“Settings”
1： “Vacuum pressure level for checking” sets the vacuum pressure to output the signal for checking the
adsorption.
2：“Adsorb error detection time” sets the time to recognize an unsuccessful adsorption, that is, vacuum
pressure to output the adsorption signal is not reached.
3：“Blow-off time of release” sets time to supply vacuum release pressure.
4：“Weight of the workpiece” enters the weight of the transferred object for each “Adsorb” command.
(3)：“Monitor sensor signal”
Pressure sensor detection pressure can be confirmed on the screen.
