Voltage control
Speed control via the supply voltage is
only permitted within the stipulated
supply voltage range. Speed control via
PWM of the supply voltage is not
permitted.
Requirements:
- Before connecting the product, ensure that the supply voltage
corresponds with the product voltage.
- Check whether the data on the nameplate corresponds with the
interface data.
Only use cables that are designed for
the current on the nameplate and the
corresponding ambient conditions.
Ensure that the electrical interface data
is adequately protected (mechanical).
Refer to the nameplate for pin connection.
Colour Operation
Wire 1 red + UB
Wire 2 blue - GND
Wire 3 violet PWM
Wire 4 white Tacho
The auxilliaries shown on the schematic diagram (which are required
for the intended use) are not part of our delivery.
