RUN Current
50%~150% (Selectable by parameter) RUN current is current value which flows onto the motor during
operation (rotation) of the motor and it is set based on rated current of the motor. * Default: 100%
STOP Current
20%~100% (Selectable by parameter) When motor stop operation, 0.1 second after motor current will be
set to STOP current value. STOP current value is a percentage of the rated current of motor. * Default: 50%
