Function setting value (Recommended: G11S)
Other than the above functions, some of the basic functions such as base frequency, maximum frequency, acceleration/deceleration time, and
motor characteristics parameters should be set.

Tips
1. G11S series for the aeration tank blower
• Because the load characteristics of the aeration tank blower
(route blower) are nearly the constant torque load character-
istics, apply FRENIC5000G11S series.
2. PID control setting values
• The optimum setting values depend on the system due to
various combinations such as the blower characteristics and
water depth of the aeration tank. Therefore, use empirical
values in advance and then reset the values to the optimum
values during test operation.
3. Energy saving operation selection considering
operation condition
• Great energy saving effect can be realized if the system has
enough treatment capacity. Set the energy saving operation
(H10) active, and continue operation unless trouble occurs.
4. Precautions on radio interference
• As many measurement circuits are installed around the
aeration tank, precautions need to be taken for radio noise
interference.
• FRENIC5000G11S series incorporates measures against
radio interference noise generation and a function for
switching to a low carrier frequency. However, we recom-
mend that you take the following action:
1) Install an isolation transformer for the power supply for the
instruments.
2) Use shielded wires for the control signals.
3) Connect Power filter (FHF- / / ) on the inverter power
supply side.
4) Install a ferrite ring for reducing radio noise (ACL-40B or
ACL-74B) on the inverter power supply side.
5) Perform complete wiring separation or electromagnetic
shielding (use metal conduits) for the wiring on the inverter
output side.
5. Full preparation to suppress harmonics with a DC
REACTOR
• An exclusive terminal (P1, P(+)) for connecting a DC
REACTOR is equipped as standard. Connect the optional
DC REACTOR (DCR - ) to reduce harmonics on
power supply side.
6. Suppression of inrush current when the power
supply is turned on
• FRENIC5000G11S series inverters have a built-in circuit that
suppresses inrush current that are generated when the
power supply is turned on. No measures have to be taken to
handle inrush current in particular.
