Installation

Tachogenerator feedback

ATTENTION: Applying the incorrect polarity to the tachogenerator

can cause an overspeed condition. Make sure the positive (+) wire is

connected to terminal T1 and the negative (-) wire is connect to

terminal T2 when the motor is running in the forward direction. Failure

to observe this precaution could result in bodily injury.

Using tachogenerator feedback improves speed regulation from

approximately 1% of motor base speed to approximately 0.1% of motor

base speed. Use tachogenerators rated from 7 VDC per 1000 RPM to

50 VDC per 1000 RPM.

Connect the tachogenerator to terminals T1 and T2 of terminal block 502

(TB502). The polarity is + for T1 and – for T2 when the motor running in

the forward direction. The polarity is reversed when the motor is running

in the reverse direction.
