(5) Encoder and controller
• Install the DC power connected to the encoder inside the same control panel as the high-speed counter
module.
• Use a cable of 3m or shorter between the encoder for the open collector output and the pulse input terminal.
• Use a cable of 10m or shorter between the encoder for the differential output and the pulse input terminal.
• Use cables of 30m or shorter between the high-speed counter module and the external output/the high-
speed counter module and the pulse input terminal.
• Be sure to attach ferrite cores to the DC power cables to be connected to the high-speed counter module
and the controller. The ferrite core ZCAT3035-1330 (manufactured by TDK Corporation) is recommended.
(6) Others
(a) Ferrite core
A ferrite core has the effect of reducing radiated noise in the 30MHz to 100MHz band. It is recommended to
attach ferrite cores if shield cables coming out of the control panel do not provide sufficient shielding effects.
Note that the ferrite cores must be attached at the position closest to the cable hole inside the control panel. If
attached at an improper position, the ferrite core will not produce any effect.
For the FG terminal on a main module that is connected to the external power supply, the external power
supply of an extension module, and CC-Link IE Field Network cables, attach a ferrite core 4cm away from the
module. (Ferrite core used for the tests conducted by Mitsubishi: NEC TOKIN ESD-SR-250, TDK ZCAT3035-
1330)
