12.3 Power Stage Configuration
12.3.1 Set the Control Mode
This function is ONLY available with Frequency Converter EFC 5610. For Fre-
quency Converter EFC 3610, ONLY 'V/f control' is available.
Code Name Setting range Default Min. Attri.
C0.00 Control mode (EFC 5610 only) 0, 1 0 – Stop
● 0: V/f control. This mode is active by default.
● 1: Sensorless vector control (SVC control)
As for permanent magnetized synchronous motor, Only option 1 is applicable.
In case of both asynchronous motor and permanent magnetized synchronous
motor, the parameters concerning Motor parameterization and SVC control
need to be set properly. For asynchronous motor, see chapter 12.11.1 "Motor
Parameterization" on page 211 and chapter 12.11.3 "SVC Control (EFC 5610
ONLY)" on page 225 respectively. For permanent magnetized synchronous
motor, See chapter 12.12.1 "The Setting of Motor Type" on page 230 and
chapter 12.12.3 "PMSM SVC control" on page 233 respectively.
12.3.2 Normal / Heavy Duty Setting
This function is used for switching the duty mode of a frequency converter ac-
cording to the load type of the actual application.
Code Name Setting range Default Min. Attri.
C0.01 Normal / Heavy duty setting 0, 1 1 – Stop
● 0: ND (Normal duty)
Change the duty mode to 'Normal duty' by modifying the parameter setting
from '1' to '0' according to the actual application.
Example:
A motor of 7.5 kW is used to drive a light load, e.g. a fan:
– Select a Frequency Converter EFC 3610 of 5.5 kW (5K50).
– Modify the duty mode of the frequency converter from 'Heavy duty' to 'Nor-
mal duty'.
● 1: HD (Heavy duty). This mode is set by default.
Example:
A motor of 7.5 kW is used to drive a heavy load, e.g. a compressor:
– Select a Frequency Converter EFC 3610 of 7.5 kW (7K50).
For overload capability and output current in ND and HD modes, see
chapter 6.1.2 "Output" on page 19.
