[HC101]～[HC121]
Automatic torque boost adjustment
Code/Name
HC101
Automatic torque boost
voltage compensation gain, 1st-motor
HC102
Automatic torque boost slip
compensation gain, 1st-motor
・If is chosen the automatic torque boost control
function in [AA121], adjustments can be made.
For more information, refer to the user's guide.
Sensorless vector control start
Code/Name
HC110
Zero speed area limit,
1st-motor
HC111
Boost value at start,
1st-motor (IM-SLV,IM-CLV)
HC112
Boost value at start,
1st-motor (IM-0Hz-SLV）
・When [AA121] is Sensorless vector control or 0Hz-Area
sensor less vector control, start boost is possible.
Secondary resistor compensation function
Code/Name
HC113
Secondary resistance
correction, 1st-motor
・This control method, in vector control (with encoder/
sensorless/0Hz), gets the temperature of the motor,
and reduces the speed variation due to temperature
change.
・If you want to use this function, use a thermistor PB-41E
from Shibaura Electronics(Ltd.) with [Cb-40]=02(NTC).
Reverse run protection function
Code/Name
HC114
Reverse run
protection enable, 1st-motor
・This function is to prevent reverse output in a low
frequency range for vector control such as (SLV/0Hz
SLV/CLV)
Motor control adjustment gain
Code/Name
HC120
Time constant of torque current
reference filter, 1st-motor
HC121
Feedforward gain compensation
adjustment for speed, 1st-motor
・[HC120] can put into effect a filter for torque command
of sensorless vector control, 0Hz sensorless vector
control and vector control with encoder.
・[HC121] adjust the compensation of the feedforward for
torque command of sensorless vector control, 0Hz
sensorless vector control and vector control with
encoder.
