● General speed modes
─ Normal operation
─ Standby mode
─ Rotation speed setting mode
8.7.1 Normal operation
The vacuum pump starts and operates at nominal rotation speed.
Setting the related parameters
1. Set the parameter
[P:002]
to "0".
2. Set the parameter
[P:026]
to "0".
3. Check the set rotation speed (parameter
[P:308]
or
[P:397]
).
8.7.2 Standby mode
Pfeiffer Vacuum recommends standby mode for during process and production stops. When standby
mode is active, the electronic drive unit reduces the rotation speed of the vacuum pump. Stand-by
mode has priority over normal operation and rotation speed setting mode.
Factory setting:
● SmartVane 55: 80% of rated speed
● SmartVane 70: 60% of rated speed
Switching on standby mode
► Press the
button.
Alternative: Operating stand-by using parameters
► Set parameter
[P:002]
to value of "1".
Alternative: Operating stand-by via "remote" interface
► Bridge pins 7 and 6 for DI standby.
Set the stand-by rotation speed
● SmartVane 55: 60 % – 100 % (800 – 1350 rpm)
● SmartVane 70: 45 % – 100 % (800 – 1800 rpm)
1. Set the parameter
[P:717]
to the required value in %.
2. Set the parameter
[P:002]
to "1".
3. Check the set rotation speed (parameter
[P:308]
or
[P:397]
).
8.7.3 Speed actuator operation
Rotation speed setting mode reduces the speed and hence the throughput of the vacuum pump. The
pumping speed changes proportionally to the rotation speed. Standby has priority over rotation speed
setting mode. The specification in rotation speed setting mode
[P:707]
sets the set rotation speed. The
rotation speed switch point varies with the set rotation speed.
Permissible rotation speed range
Settings in the rotation speed mode or stand-by mode are subject to the permissible rota-
tion speed range of the respective vacuum pump (technical data). The electronic drive unit
adjusts the set rotation speed automatically to the next valid value.
Set the rotation speed setting mode
1. Set the parameter
[P:707]
to the required value in %.
2. Set the parameter
[P:026]
to "1".
3. Check the set rotation speed (parameter
[P:308]
or
[P:397]
).
8.8 Operating mode display via LED
LEDs on the electronic drive unit show the basic operating states of the vacuum pump. A differentiated
error and warning display is only possible for operation with the Pfeiffer Vacuum display and control unit
or a PC.
