4.2.97 Sensorless vector, 0 Hz domain control 

The 0Hz domain sensorless vector (SLV) control function 
incorporates Hitachi’s own torque control system and enables 
high-torque operation in the 0Hz range (0 to 3 Hz). This control 
function is best suited for driving a lifting machine, e.g., crane or 
hoist, that requires sufficient torque when starting at a low 
frequency. 
To use this function, specify "04" for the V/F characteristic curve 
selection (A044/A244). 
Before using this function, be sure to optimize constant settings 
for the motor with reference to Section 4.2.91, "Motor constant 
selection." 
The parameters related to the 0Hz-range sensorless vector control 
are as follows: 
1) The Zero LV lmit for 1st/2nd motors (H060/H260) is the 
parameter that specifies the output current for the 
constant-current control in the 0 Hz range (about 3.0 Hz or less). 
The parameter value is expressed as a ratio of the output current 
to the inverter's rated current. 
2) The Zero LV starting boost current (H061/H261) is the parameter to specify the current for boosting at motor 
start-up with a frequency in the 0 Hz range. The parameter value is expressed as a ratio of the boost current to the 
inverter's rated current. The value of the boost current is added to the current value specified by "H060/H260" only at 
starting.

When using this function, observe the following precautions: 
1)    Be sure to use an inverter of which the capacity is one class higher than the motor to be driven. 
2)    If you use the inverter to drive a motor of which the capacity is two classes lower than the maximum applicable 

capacity of the inverter, you may not be able to obtain adequate motor characteristics. 

3)    If you cannot obtain desired characteristics from the motor driven under the 0Hz-range sensorless vector control, 

readjust the motor constants according to the symptom as described in the table below.

Adjustment method 

Adjustment item 

Powering 

Momentary speed 
variation is negative. 

Increase the motor constant R2 step by step from the set 
value up to 1.2 times as high as the set value. 

H021/H221/H031 

Momentary speed 
variation is positive. 

Reduce the motor constant R2 step by step from the set 
value down to 0.8 times as high as the set value. 

H021/H221/H031 

Regenerating 

Torque is insufficient at 
low frequencies (several 
Hz) 

Increase the motor constant R1 step by step from the set 
value up to 1.2 times as high as the set value. 

H020/H220/H030 

Increase the motor constant I0 step by step from the set 
value up to 1.2 times as high as the set value. 

H023/H223/H033 

Starting 

The motor generates an 
impact when it starts. 

Reduce the motor constant J from the set value. 

H024/H224/H034 

Decelerating 

The motor runs 
unsteadily. 

Reduce the speed response setting. 

H005/H205 

Reduce the motor constant J from the set value. 

H024/H224/H034 

Immediately 
after 
deceleration 

Overcurrent or 
overvoltage protection 
function operates. 

Reduce the motor constant I0 step by step from the set 
value down to 0.8 times as high as the set value. 

H023/H223/H033 

Specify "00" (always on) or "01" (always off) for the AVR 
function select (A081). 

A081 

Low-frequency 
operation 

Motor rotation is 
inconsistent. 

Increase the motor constant J from the set value. 

H024/H224/H034 

Note 1:  Always set the carrier frequency (b083) to 2.1 kHz or more. If the carrier frequency is less than 2.1 kHz, the 

inverter cannot operate the motor normally. 

Note 2:  Adjust the torque limit (b041 to b044) so that the value "

" calculated by the expression below does not 

exceed 200%. Otherwise, the motor may be burnt out. 

 

 = "torque limit" x (inverter capacity)/(motor capacity) 

(Example)  When the inverter capacity is 0.75 kW and the motor capacity is 0.4 kW, the torque limit value is 

calculated as follows on the assumption that the value "

" should be 200%: 

 

Torque limit (b041 to b044) = 

 x (motor capacity)/(inverter capacity) = 200% x (0.4 kW)/(0.75 

kW) = 106%
