Setting The Carrier Frequency - Omron EasySpeed 3G3JE User Manual

Operation
3-6-9 Selecting Reverse Rotation Prohibition
• This parameter is used to specify whether to enable or disable a reverse rotation command sent to
the Inverter.
• The parameter must be set to prohibit reverse operation when the Inverter is applied to applications
in which reverse rotation of the Inverter would cause problems.
P13 Reverse rotation prohibit selection

3-6-10 Setting the Carrier Frequency

• With the 3G3JE, it is possible to switch between two carrier frequencies.
• Change the carrier frequency in the following cases.
Reduce the carrier frequency to 4 kHz if there are fluctuations in the speed or torque at low speeds
or if the wiring distance between the Inverter and motor is excessively long.
Wiring distance
50 m or less
Longer than 50 m
