Design Guide | iC2-Micro Frequency Converters
Common-mode cores mitigate high-frequency noise in the motor cable. As a result, limited loss is added to the system.
l
Motor cable
Losses in the motor cable are mainly caused by ohmic losses, but due to the switching frequency of the frequency converter, losses are
also caused by capacitive coupling to ground. Losses due to capacitive coupling can be reduced by carefully selecting the motor cable
and keeping the cable length as short as possible. If a sine-wave filter is used on the frequency converter output, the loss caused by
capacitive load is lower.
Motor
Motor losses depend on the motor type and efficiency category selected. IEC60034-30-1 defines the different efficiency classes from IE1
to IE4.

Power Hardware

3.4
iC2-Micro Frequency Converters are designed to fit a wide variety of installation locations. The units are available in different protection
ratings, making them suitable for installation in cabinets, directly on machines, in dedicated control rooms, and freely installed.
IP20/Open Type is designed for installation in enclosed cabinets and similar setups.
l
IP21/UL Type 1 (IP21/Type 1 conversion kit as an option) is designed for indoor installations.
l
iC2-Micro Frequency Converters are suitable for use in a wide temperature range. The operating temperature range is from -20 °C to
+55 °C (-4 °F to +131 °F) and -10 °C to +50 °C (14 °F to +122 °F) without derating.
The motor output of the iC2-Micro Frequency Converters is protected against short circuit, ground fault, and overload. Thermal
monitoring is also provided to protect the motor. Unlimited switching on output enables using a contactor or disconnects between the
drive and the motor.
Integrated filters optimize EMC performance, reduce harmonics on the grid, and match with output requirements. Built-in EMC filters can
be configured to fit the EMC-related installation requirements. The offering covers:
Drives without filter (C4 compliant variants).
l
Drives with filters for use in industrial networks (C2 compliant variants) and domestic installations (C1 compliant variants).
