Overal Dimmensions
Electrical Connection
Use U3 for 0–10 VDC or PWM speed control. Recommended PWM amplitude is 10 VDC with a frequency of 1–10 kHz. U4 provides the FG tachometer output at 2 pulses per revolution; the customer supplies the pull-up circuit with Vfg of 3.3–30 VDC.
| Terminal | Wire Color | Connection | Function |
| U1 | Red | +24 VDC | Power supply positive |
| U2 | Blue | GND | Power supply ground |
| U3 | Yellow | 0–10 V / PWM | Speed control input |
| U4 | White | FG | Tachometer, 2 pulses/revolution |
