General Hints and Explanation of Terms
To ensure safe and trouble–free operation, the following
points should be taken into consideration when circuits
are being constructed or in the design of printed circuit
boards.
D The connecting lines from C₂ to Pin 6 and Pin 2 should
be as short as possible, and the connection to Pin 2
should not carry any additional high current such as
the load current. When selecting C₂, a low tempera-
ture coefficient is desirable.
D The common (earth) connections of the set–point gen-
erator, the tacho–generator and the final interference
suppression capacitor C₄ of the f/V converter should
not carry load current.
D The tacho generator should be mounted without
influence by strong stray fields from the motor.
