P007 Torque Boost
●
Torque boost level corresponding to load characteristics can be set. The
larger the setting value is, the higher output voltage and torque boost will
be.
・
After the mode is set to “auto torque boost”, the output voltage will change
automatically according to the load fluctuation. To set “Auto torque boost”,
please press
T
(down) button when the operation panel displays “0”.

Method of increasing torque at lower speed
・
If higher torque is required at lower speed, the torque boost level can be set
to a larger value, thus generating higher output voltage to increase the torque.
・
If the boost level setting is too high, it may cuase overcurrent fault, overload
fault, motor overheating or excessive noise.
・
The motor current will rise after the boost level increases. Please carefully
consider the settings for “P016: Electronic Thermal Select” and “P017:
Thermal Current Setting”.
・
Once it is set to “vector control”, the settings for parameter “P129: Vector
Control Select =1” and parameter “P007: Torque Boost” will become invalid.
・
During auto torque boost setting, parameter “P130: Motor Capacity”, “P131:
Motor Pole Number” and “P133: Voltage Compensation Constant” must be set.
The setting for “P133: Voltage Compensation Constant” can be tuned
