Stall prevention (overcurrent)

Description

During 
acceleration

When the output current (output torque during real sensorless vector control or vector 
control) of the inverter exceeds the stall prevention operation level (

Pr. 22 Stall prevention 

operation level

, etc.), this function stops the increase in frequency until the overload 

current decreases to prevent the inverter from resulting in overcurrent trip.  When the 
overload current has decreased below stall prevention operation level, this function 
increases the frequency again.

During 
constant-
speed 
operation

When the output current (output torque during real sensorless vector control or vector 
control) of the inverter exceeds the stall prevention operation level (

Pr. 22 Stall prevention 

operation level

, etc.), this function reduces frequency until the overload current 

decreases to prevent the inverter from resulting in overcurrent trip.  When the overload 
current has decreased below stall prevention operation level, this function increases the 
frequency up to the set value.

During 
deceleration

When the output current (output torque during real sensorless vector control or vector 
control) of the inverter exceeds the stall prevention operation level (

Pr. 22 Stall prevention 

operation level

, etc.), this function stops the decrease in frequency until the overload 

current decreases to prevent the inverter from resulting in overcurrent trip.  When the 
overload current has decreased below stall prevention operation level, this function 
decreases the frequency again.

Check point

1. Check that the 

Pr. 0 Torque boost

 setting is not too large.

2. Check that the 

Pr. 7 Acceleration time

 and 

Pr. 8 Deceleration time

 settings are not  too small.

3. Check that the load is not too heavy.
4. Are there any failure in peripheral devices?
5. Check that the 

Pr. 13 Starting frequency

 is not too large.

·

 

Check the motor for use under overload.

6. Check that the 

Pr. 22 Stall prevention operation level

 is appropriate.

Corrective action

1. Increase or decrease the 

Pr. 0 Torque boost

 value 1% by 1% and check the motor status. 

(Refer to page 59.)

2. Set a larger value in 

Pr. 7 Acceleration time

 and 

Pr. 8 Deceleration time

. 

(Refer to page 61.)

3. Reduce the load weight.
4. Try advanced magnetic flux vector control, real sensorless vector control or vector control.
5. Change the 

Pr. 14 Load pattern selection

 setting.

6. Set stall prevention operation current in 

Pr. 22 Stall prevention operation level

. (The initial value is 

150%.) The acceleration/deceleration time may change. Increase the stall prevention operation level 
with 

Pr. 22 Stall prevention operation level

, or disable stall prevention with 

Pr. 156 Stall prevention 

operation selection

. (Use 

Pr. 156

 to set either operation continued or not at OL operation.)

Stall prevention (overvoltage)

Description

During 
deceleration

· If the regenerative energy of the motor becomes excessive and exceeds the 

regenerative energy consumption capability, this function stops the decrease in 
frequency to prevent overvoltage trip. As soon as the regenerative energy has 
decreased, deceleration resumes.

· If the regenerative energy of the motor becomes excessive when regeneration 

avoidance function is selected (

Pr. 882

 = 1), this function increases the speed to 

prevent overvoltage trip. 

(Refer to chapter 4 of  

 the instruction manual (applied).)

Check point

· Check for sudden speed reduction.
· Regeneration avoidance function 

(Pr. 882 to Pr. 886)

 is being used? 

(Refer to chapter 4 of  

 the 

instruction manual (applied).)

Corrective action

The deceleration time may change.
Increase the deceleration time using 

Pr. 8 Deceleration time
