d1-01~d1-08 is used for multi-stage V/f mode. Voltage value 100% corresponds to rated
voltage of motor. Please suitably set the values of frequency and voltage at knees on the basis
of characteristics of motor and load. Improper setting may rise output current even burn the
motor.
d1-09
Torque boost
Range: 0.0%~30.0%
Factory default:
0.0%
Under V/f pattern, output voltage at low frequency can be compensated by this parameter,
improving the torque output. 0.0% corresponds to automatic torque boost, and drive output
voltage is automatically compensated via detection of load current. Automatic torque boost is
valid only for linear V/f pattern.
100% of torque boost corresponds to rated voltage of motor. A non-zero value means the
output voltage rises on the basis of V/f curve and this takes effect at parameter values 0~6 of
d1-00. It is suggested this parameter value be gradually increased from z ero until the starting
requirement is met. Boost value is not suggested to be set to a relatively big one, as it is likely
to bring about a bigger drive current and higher motor temperature.
