Adjusts the torque boost only during open loop operation (LC01 Control Mode = Open
Loop V/Hz). If the torque boost is too low, the motor may not be able to lift the load or
cause an Error Low Motor Current
If open loop vector is selected, set to 1.00. If oscillations or vibrations are felt, reduce in
steps of 0.1 (1.0 --> 0.9 --> 0.8 etc.).
LC34 Digital Pre-torque
When US04 Control Mode = Digital Speed Selection (0), and Binary Speed Selection (1),
Absolute Analog Speed (2), Bi-Polar Analog Speed (3), and Serial Binary Speed
DIN66019, Serv.50 (6), this parameter provides a fixed pre-torque value (percent of
motor torque) and can compensate for roll back at one load condition (i.e. empty car).
This can be used when no load weigher is present. An additional gain and offset may be
applied to this value using LA15 Analog Input 2 Gain and LA17 Analog Input 2 Offset.
