Over-current Stall Prevention during Acceleration

Settings
 If the motor load is too large or drive acceleration time is too short, the AC drive output current may
increase abruptly during acceleration and it may cause motor damage or trigger protection
functions (OL or OC). This parameter is used to prevent this situation.
