8.4.1 Normal operation
Permissible rotation speed range of the vacuum pump
Parameterization in rotation speed setting mode is subject to the permissible rotation speed
range of the respective vacuum pump. The electronic drive unit regulates automatically to
the next valid value.
The vacuum pump starts in normal operation with the pump-specific nominal rotation speed.
Set parameters
1. Set parameter
[P:002]
to "0".
2. Query the actual speed via parameter
[P:398]
.
3. Set the desired speed via parameter
[P:706]
.
8.4.2 Stand-by operation
Permissible rotation speed range of the vacuum pump
Parameterization in rotation speed setting mode is subject to the permissible rotation speed
range of the respective vacuum pump. The electronic drive unit regulates automatically to
the next valid value.
Pfeiffer Vacuum recommends stand-by operation for the vacuum pump during breaks in processes or
production.
● If stand-by mode is active, the electronic drive unit reduces the rotation speed of the vacuum
pump in the range of
25 to 100%
of the nominal speed.
● The factory configuration for stand-by is 30%.
● Stand-by operation has priority over rotation speed setting mode.
Set the stand-by rotation speed
1. Set the parameter
[P:717]
to the required value in %.
2. Set the parameter
[P:002]
to "1".
3. Query the actual speed via parameter
[P:398]
.
8.4.3 Rotation speed setting mode
Permissible rotation speed range of the vacuum pump
Parameterization in rotation speed setting mode is subject to the permissible rotation speed
range of the respective vacuum pump. The electronic drive unit regulates automatically to
the next valid value.
The set rotation speed is selected via the parameter
[P:707]
in the range
25 to 100 %
of the set rotation
speed.
Rotation speed setting mode has priority over normal operation.
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. Query the set rotation speed via parameter
[P:309]
or
[P:398]
.
8.5 Operation monitoring
8.5.1 Operating mode display via LED
LEDs on the operator panel of the electronic drive unit indicate the respective operating status of the
vacuum pump.
