LSIS LSLV-S100 - Torque Boost

135
Learning Basic Features
The 100% output voltage in the figure below is based on the parameter settings of bA.15
(motor rated voltage). If bA.15 is set to 0 it will be based on the input voltage.
• When a normal induction motor is in use, care must be taken not to configure the output
pattern away from a linear V/F pattern. Non-linear V/F patterns may cause insufficient motor
torque or motor overheating due to over-excitation.
• When a user V/F pattern is in use, forward torque boost (dr.16) and reverse torque boost
(dr.17) do not operate.
4.14 Torque Boost
Manual Torque Boost
Manual torque boost enables users to adjust output voltage during low speed operation or
motor start. Increase low speed torque or improve motor starting properties by manually
increasing output voltage. Configure manual torque boost while running loads that require
high starting torque, such as lift-type loads.
