10.4 Power filter
Power filter is installed to prevent the PWM circuit in amplifier from exerting influence over the power supply side.
In the amplifier, the PWM circuit performs high frequency switching. This causes power line noise, radiation noise from the amplifier and
noise from the motor power cable, and these noises may have an adverse influence over external equipment. To prevent such an influence,
the following methods are available. Refer to figure below.

(a) Installation of amplifier in a grounded steel container. Avoid close installation with personal computer and measuring instrument.
(b) Installation of power filter at primary side of amplifier to prevent PWM from exerting influence over power source.
(c) Install the cable from each amplifier to motor in a grounded metal conduit.
(d) Minimize the distance of ground connection by using a larger size copper bar. Ground connection should be wiried to each equipment
separately. See figure below.

(1) Copper bar
(e) Avoid mutual connection of the following cables.
(i) Ground : Power system and frame (enclosure)
(ii) + 24 [V] DC for control input/output and 0 [V] of power supply
(iii) 0 [V] power supply : Speed command and encoder
(f) Avoid binding together the 200 [V] power supply and amplifier output cable, + 24/+ 15 [V] DC control signal cable and encoder cable or
laying them in parallel.
(g) Separate 200 [V] power source with that of 100 [V]-system device by use of an insulating transformer : Fuji “TRAFY”, etc. .
