The standard operating mode of the iC5
Inverter is VxF. This is the simplest form of
operation and controls Volts and Frequency to
vary the speed of a standard Induction Motor.
The iC5 can also operate in Sensorless Vector
mode. This can improve motor performance
without requiring a separate feedback device.
Sensorless Vector mode operates in the same
way as VxF but performs a number of
calculations to improve low speed torque.
This requires an “ID” run during which the
Inverter runs the motor for approx. 1 minute at
various speeds to gather the necessary data.
Decouple the motor from the machine
before starting an ID run.
Default is 0. Change to 3 to enable Sensorless Vector Mode.
Default is 0. Ensure motor is off-load before changing to 1 to begin ID run.
