Separate suppressor diodes (D1, D2) for Up and Umot if they
have separate supply voltages.
If only one supply voltage is used, (bridge between Up and
Umot), one suppressor diode (D1) is sufficient. D1 and D2 e.g.
P6KE33A from STMicroelectronics
NOTE
Exceptions:
It may not be necessary to implement the additional EMC measures named. If the motor is fed e.g.
from a CE-conforming power supply unit, the EMC suppressor circuit can be dispensable. In this case
the power supply unit takes on the function of the EMC suppressor circuit according to circuit
diagram 2.
NOTE
Motor without attachment:
A CE-conforming control, e.g. Faulhaber's SC 2804, is recommended for operation of the servomotor.
