E.1. Common-mode motor filter
A common-mode motor filter can be considered when following situations occur.
(1) For the drive with the 17-bit encoder, the encoder feedback is disturbed and the error
of “serial encoder communication error” occurs when the drive is enabled.
(2) Reduce the common-mode noise at the drive’s output.
The part number of HIWIN self-made common-mode motor filter is MC-CM-S. It is suitable for
D2-series drives with the power less than 2 KW (inclusive). The specification is given in the
following table. When the external common-mode motor filter is used, the effect of common-
mode inductor should be considered to improve the performance of motor control.

If the drive is operated below the maximum temperature, no cooling fan is required.
However, if the ambient temperature exceeds 50°C, an external fan should be used for
cooling. The fan should have a flow rate of at least 110 cubic feet (CFM).
