Due to technical reasons the output voltage amounts to approx. max. 95 % of the applied mains
voltage.
In order to still be able to achieve the maximum air
fl
ow of the connected fans, an increase of the
maximum frequency is possible for our motors. For this, a current increase must be included in the
calculation. It is necessary to optimize monitoring of motor current, output voltage, and speed using
suitable measuring instruments.
The factory set values are for voltage controllable external rotor motors with 400 V / 50 Hz.
After veri
fi
cation of the motor speci
fi
cations, adjustments are to be adapted, if applicable.

Startvoltage
Startvoltage
The start voltage is used to apply enough torque to the motors to insure they will run at
low speed.
Attention! In order to prevent over current and unnecessarily high thermal load of the
motor, do not select to high a setting.
