Motor Control Chapter 4
• Induction FV (3) – Induction motor, flux vector control mode.
Connected to an induction motor. Used when high performance precise
speed regulation and/or position control closed loop is required. Can also
be configured with direct Torque Reference input. Can also be used open
loop with less precision.
• PM VHz (4) – Permanent magnet motor, volts per Hertz control mode.
Connected to a Surface Permanent Magnet motor (SPM) or Permanent
Magnet Synchronous Motor (PMSM). Used for variable torque
applications with improved efficiency energy savings and variable speed
constant torque applications such as conveyors. Also used in multi-motor
or synchronous motor open loop applications.
• PM SV (5) – Permanent magnet motor, sensorless vector control mode.
Connected to a Surface Permanent Magnet motor (SPM) or Permanent
Magnet Synchronous Motor (PMSM). Used for constant torque
applications. Provides excellent starting, acceleration, and running torque.
• PM FV (6) – Permanent magnet motor, flux vector control mode.
Connected to a Surface Permanent Magnet motor. Used when high
performance precise speed regulation and/or position control closed loop
is required. Can also be configured with direct Torque Reference input.
Can also be used open loop with less precision.
• SyncRel VHz (7) – Synchronous Reluctance motor, volts per Hertz
control mode.
Connected to a Synchronous Reluctance motor. Used for constant torque
applications with improved efficiency energy savings and variable speed
applications such as conveyors. Used in multi-motor applications.
• SyncRel SV (8) – Synchronous Reluctance motor, sensorless vector control
mode.
Connected to a Synchronous Reluctance motor. Used for constant torque
applications with improved efficiency energy savings and variable speed
applications such as conveyors. Avoid slow speed low inertia applications
that cause torque ripple effects.
• Adj VltgMode (9) – Adjustable voltage control mode.
Independent Frequency and Voltage regulators; Fixed Frequency and
Variable Voltage or Fixed Voltage and Variable Frequency. Typically used
for non-motor applications such as resistive and inductive heating
elements, vibration welding, power supplies, Electromagnetic stirring of
molten metal and some Linear Induction Motor LIM applications.
• IPM FV (10) – Interior permanent magnet motor, flux vector control
mode.
Connected to an Interior Permanent Magnet motor. Used when high
performance precise speed regulation and/or position control with closed
loop feedback is required. Can also be configured with direct Torque
Reference input. Can also be used open loop with less precision.
