5.4 Entering The Operating Data
5.5 Induction Motors
5.5.1 Motor Overload
The COMBIVERT drive supports six different control modes, digital
speed selection and control, analog speed control, analog torque control.
The drive's I/O will need to be set up according to the desired scheme.
From the table below select the desired control scheme and adjust the
corresponding number in parameter LF.2.
Control Mode
Absolute Analog Speed Control
Digital Speed Selection
Analog Speed Control
Analog Torque Control
Analog Speed Control
Binary Speed Selection
The COMBIVERT drive utilizes robust algorithms for controlling the
motor, therefore even with minimum information about the motor, good
performance can still be achieved. However a few basic parameters are
required. Their adjustment is outlined below. For purposes of identifying
the type of motor in use the following convention will be utilized in this
manual. AC induction motors will be referred to as "IM" and AC permanent
magnet synchronous motor will be referred to as "PM"
Before you begin to enter the motor data verify that parameter LF.3 is
set to conF configuration.
The COMBIVERT Drive is capable of driving either induction motors,
referred to from here on as "IM" or permanent magnet motors referred
to from here on as "PM"
Verify in LF. 4 that the correct motor configuration is loaded and then
follow the steps listed below based on what type of motor you have.
The COMBIVERT drive is capable of providing solid state motor overload
protection. If it is desired that the drive provide this protection, turn the
function "on" in parameter LF.08. Then adjust the motor full load amps
(FLA) in parameter LF.0. Enter the IM power (hp) in LF.10.
