Speed Control Settings

Control Method	Operating Condition
Full speed	Short the red (+10 V) and yellow (speed-control) conductors.
0–10 VDC	Motor starts above 1.0 V and stops below 0.5 V.
PWM	Frequency 1–10 kHz; recommended amplitude 10 V ±5%. Motor starts above 10% duty and stops below 5% duty.
Potentiometer	A 10 kΩ potentiometer is recommended.

Note

1	Connect the power and control conductors strictly according to the wiring diagram.
2	Do not connect the white signal conductor directly to the red conductor or to an external DC power supply.
3	If the blower does not start, check the speed-control input and prevent injury from an unexpected start; do not touch the impeller or rotor while energised.
4	Startup may take several seconds. Do not touch the impeller or rotor while energised or operating at low speed.
5	Persons lacking appropriate physical, sensory or mental capability or experience must use the blower only under responsible supervision. Keep children away.
6	A damaged power cable must be replaced by the manufacturer.
7	The motor must not be operated alone without an impeller or load.
8	For storage after unpacking, repack the product and keep it at -40 to +80 °C, RH ≤95%, in a clean ventilated area free of corrosive gases and at least 15 cm above the floor.
9	Read this technical specification carefully before use.
