Design and Installation
Note The same noise filter cannot be used for Servomotor output lines as for the power supply.
Install surge killers for loads that have induction coils, such as relays, solenoids, brakes, clutches, etc.
The following table shows types of surge killers and recommended products.
Note Thyristors and varistors are made by the following companies. Refer to manufacturers documen-

Diodes are relatively small devices such as relays used
for loads when reset time is not an issue. The reset time
is increased because the surge voltage is the lowest
when power is cut OFF. Used for 24/48-VDC systems.
Thyristor and varistor are used for loads when induction
coils are large, as in electromagnetic brakes, solenoids,
etc., and when reset time is an issue. The surge voltage
when power is cut OFF is approximately 1.5 times that
of the varistor.
Use capacitors and resistors for vibration absorption of
surge when power is cut OFF. The reset time can be
shortened by proper selection of the capacitor or resis-
tor.
Ordinary noise filters are created for a power supply frequency of 50/60 Hz, so con-
necting an output of 10 kHz (the Position Driver’s PWM frequency) can generate an
extremely high (approximately 100 time the normal) leakage current flow to the ca-
pacitor in the noise filter and cause damage to the Position Driver.
