[HC101] to [HC115]
Automatic torque boost adjustment
Code/Name
HC101
Automatic torque boost
voltage compensation gain, 1st-motor
HC102
Automatic torque boost slip
compensation gain, 1st-motor
・These parameters are adjusted when the automatic
torque boost control function is selected in [AA121].
For more information, please contact your supplier
or local Hitachi inverter sales office.
Vector control start adjustment
Code/Name
HC110
Zero speed range limit,
1st-motor(IM-0Hz-SLV)
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-range
sensorless vector control, start boost is possible.
Secondary resistor compensation function
Code/Name
HC113
Secondary resistance
(R2) correction, 1st-motor
・When the vector control (with encoder/ sensorless/0Hz)
is being used and the temperature of the motor can be
sensed, the inverter is capable of reducing the speed
variations due to temperature changes.
・If use this function, use a thermistor PB-41E from
SHIBAURA ELECTRONICS CO., LTD.
And also, it is necessary to set [Cb-40] to 02 (NTC).
Reverse run protection function
Code/Name
HC114
Direction reversal
protection, 1st-motor
・This function is to prevent the change of direction of the
output in a low frequency range for vector control such
as (SLV/0Hz-SLV/CLV).
Torque reference value conversion method
Code/Name
HC115
Torque conversion
method selection, 1st-motor *1)
*1) [HC115]/[HC215] are parameters added to Ver2.02 or
later.
• Select the 100% reference value of the torque related
setting parameter. (Setting 01 is the same method as
the SJ700 series.)
For more information, please contact your supplier
or local Hitachi inverter sales office.

・[HC120] to [HC142] are effective when the control mode is
sensorless vector control(IM), Zero-Hz-range sensorless vector
control (IM) or Vector control with encoder (IM).
・[HC120] sets a filter for torque command.
・[HC121] adjusts the compensation of feedforward control.
・[HC137] adjusts the magnetic flux establishment level at start
up. If this is set to a small, the waiting time until acceleration
starts can be shortened, but the startup operation may become
unstable.
・[HC140] adjusts the output current level during pre-excitation.
The basis current value is as follows depending on the control
mode.
08:Sensorless vector control (IM)
09:Vector control with encoder(IM)
10:Zero-Hz-range sensorless vector
control
・[HC141]/[HC142] adjust the upper limit of the inverter output
voltage level. By increasing these parameters the output
current may be reduced, and the operation may become
unstable.
Be sure to set the same value for [HC141] and [HC142].
