nDifference between CT and VT
The characteristics of CT (low carrier, constant torque) and VT (high carrier, variable torque) are shown
below.
nSetting Precautions
C6-01 (CT/VT Selection)
When setting C6-01, observe the following precautions.
• Depending on the set value in C6-01, the setting range of the related parameters is limited as follows:
* Factory settings depend on Inverter capacity.
200 V and 400 V Class Inverters for 0.4 to 22 kW: 6 (15 kHz)
200 V Class Inverters for 30 to 90 kW, or 400 V Class Inverters for 30 to 185 kW: 4 (10 kHz)
200 V Class Inverter for 110 kW, or 400 V Class Inverters for 220 to 300 kW: 1 (2 kHz)
• When the setting in E1-04 or E3-02 is greater than 150 Hz, if C6-01 is set to 0, an OPE02 (Parameter set-
ting range error) will occur.
CT: Low Carrier, Constant Torque VT: High Carrier, Variable Torque
Constant torque means a fixed load torque for all motor
speed, and it requires overload resistance capability.
Applications include pushers, conveyors, cranes, and
other friction or heavy loads.
Var ia bl e torque means that the load torque will decrease
as the speed decreases. Normally, overload resistance
capability is not required. Applications include fans and
pumps.
Low carrier: Acoustic noise is present. High carrier: Acoustic noise is not present.
