MSC-3 Start Up
C04 FLUX PLUS
The MSC-3 uses a sensorless ux vector control algorithm to control the motor operation. This control
algorithm provides independent control of motor ux throughout the speed range and is highly robust
against motor parameter changes. It uses the motor nameplate parameters entered in the B00 MOTOR
menu as the basis for its calculations to produce the correct ux in the motor. For a motor to produce
full torque it must have the correct ux applied to it. This is particularly critical at low speed. Flux Plus
adjusts the motor ux estimate to provide additional control where specic adjustments to the motor
torque response are required.

0.0%
Range: 0 to 150% of adjustment range
• Press to edit the value.
• Press ▲/ ▼ to make changes to the value.
• Press to accept the new value OR
• Press ESC to abandon the value change.
This feature enables an adjustment in the ux vector algorithm that can increase motor ux to produce
more torque for the same motor current. The amount of extra torque produced will vary from motor to
motor depending on motor size, efciency and the operating speed. Increase the value to produce more
torque. This should be done in small steps to ensure the drive does not go into Current Limit. If the drive
does go into current limit decrease the Flux Plus value slightly. This is the maximum torque that the
motor can produce.

DISABLED
Available Choices: ENABLED
DISABLED
• Press once to begin.
• Use the ▲ / ▼ buttons to enable or disable the high speed ux plus.
• Press to conrm the choice.
When disabled the ux plus decreases with increasing speed. This allows more efcient operation of
the MSC-3 on loads that have a high starting torque but do not require any extra torque during normal
operation. If your load requires high torque throughout the entire speed range then enable C041 HiSpd
Flux+.
