• Set the parameters when it is desired to improve the performance in the shortest
acceleration/deceleration mode.
(1) Pr. 61 "reference current"
Set the current value (A) that is referenced for stall prevention operation level.
Set this value when you want to use the motor rated current as reference such as
when capacities of the motor and inverter differ.
Setting
9999 (factory setting)
0 to 500A
(2) Pr. 62 "reference current for acceleration"
Set the stall prevention operation level (%) at acceleration.
Set when you want to restrict torque at acceleration, etc.
The value set in Pr.61 "reference current" becomes the reference value (100%).
Setting
9999 (factory setting)
0 to 200%
(3) Pr. 63 "reference current for deceleration"
Set the stall prevention operation level (%) at deceleration.
Set when you want to restrict torque at deceleration, etc.
The value set in Pr.61 "reference current" becomes the reference value (100%).
Setting
9999 (factory setting)
0 to 200%
Reference Current
Referenced from rated inverter current
Referenced from setting (rated motor current)
Reference Current
150% (180%) is the limit value.
The setting of 0 to 200% is the limit value.
Reference Current
150% (180%) is the limit value.
The setting of 0 to 200% is the limit value.
