<Note>
Calibrate the scale of the tachometer (TM) from the potentiometer on
the rear panel.
1. While running the motor at its full rotation speed without load,
adjust to 1450 min
-1
if power supply is at 50 Hz, or 1750 min
-1
if
60 Hz.
2. Monitor the output signal of the TG on an oscilloscope and
determine the frequency. And adjust:
rotating speed N (min
-1
) = 5 x f (Hz)
Caution: Since the circuit is not isolated from the power supply,
use an insulated tool such as an insulated screwdriver to protect
against electric shock.
External braking resistor (DVOP003)
5.6 10W
<Precautions>
The resistance of DVOP003 is 5.6 . When using commercially available
resistor, choose 4.7-6.8 , 10 W or larger.

<Precautions>
· Connect the tachometer in parallel with the tachometer generator (TG).
· If the tachometer (TM) requires longer connection cable, use shielded
twisted pair cable. Don't ground shielding of the cable.
· Accuracy of tachometer readings will depend on variation in motor
performance and operating environment (temperature and noise). The
tachometer should be used as a rough indicator.
