4.2.2 Precautions for Wiring (R.F.I)
Servopack is a divice for speed control of i000: i, Servopack is not provided with a protection from
radio frequency interference. If the controller
and thus its wiring needs great precaution. The
signal level must process 6 mV or less and therefore is troubled by radio wave, connect a noise filter
to power supply. See Par. 3.5.1.

The loss can be ignored when the start and stop are not fre-
