LSIS LSLV-S100 - Torque Boost; Manual Torque Boost

98
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
4.14.1 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.
