■ Semi-standard products (Products in regular production)
● A PWM signal from the customer equipment is input to the control line (blue) of the fan motor forvariable-speed operation of fans and blowers. (Input and noise can be reduced when the internaltemperature of the customer equipment is low, such as during idling.)

● Aside from the above models, please see also the high pressure, variable speed G series fans. Details may be found in specs G-31 to G-36.● The lineup of variable-speed fans and blowers will be expanded regularly. Visit the NIDEC SERVO Website for information on the latest lineup.● Direct your inquiry to NIDEC SERVO for connector termination to lead wires, for sensor specifications other than those contained in the catalog and forvariable speed specifications. (Products tailored to voltage command control and resistance value command control are also available)
● To ensure correct installation and smooth operation please obtain a drawing for approval or reference drawing from NIDEC SERVO Co.
●Standard values for PWM control signal - speed specification (at rated voltage, open, and normaltemperature and humidity)
*1: Can be installed only on outlet side. *2: Can be installed only on intake side. All guards conform to the UL standard when combined with NIDEC SERVO fans. The installation of a filter, guard and other accessories will constitute a ventilating load,reducing the airflow.Select a suitable guard, taking into consideration the increase in airresistance. (See Figs. 12 and 13 on page G-7.)
List of mating fan seriesF60UL
The DC fans and blowers of NIDEC SERVO have a function to send analarm signal when the fan motor revolutions slow down. Several systemsare used to cut off the system power supply by this alarm signal, with threetypes of sensors available. Select the right type of sensor in accordance withthe purpose of use. The lead wire for the sensor is yellow. The output type isan open collector output for all three types.
■■ Sensor type
1. Lock detection type (Product code: S)
The output signal indicates an [L] state (transistor is ON) while thepropeller is rotating, changing to an [H] state (transistor is OFF) less thanfive seconds after the propeller stops rotating. The propeller automaticallyrestarts operation within five seconds when the lock is unlocked. ([H] → [L]5 s). If the pull-up voltage is live, the [H] state (transistor is OFF) will engagein less than five seconds, even when the power is turned off.
2. Pulse output type (Product code: P)
A rectangular wave of two pulses will be output for each turn of thepropeller while the propeller is rotating, outputting two types of signaldepending on the propeller position when the propeller is locked. (See thenote below ※)
3. Speed detection type (Product code: Q)
The output signal indicates the [H] state when the propeller revolutions areslower than the preset speed, changing to the [L] state when the propellerrevolutions exceed the reset speed. [Products with a reversed output waveform are also available, suitable for awired OR connection when several fans are installed. Contact NIDECSERVO for further information. {Former code: SQ, new code (15 - digit codeproducts): R} ]
Note: The output waveform for type SQ (R) will be reversed.The speed setting for the alarm output is about half the rated speed.For more detailed information, please request a product delivery specificationfrom NIDEC SERVO.
