Pull-in Current @
Acceleration
Sets the pull-in current allowed to flow during acceleration/deceleration as a percentage of
the motor rated current.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the motor
rated current.
• A1-02 = 5 [OLV/PM]: E5-03 [Motor Rated Current (FLA)]
• A1-02 = 8 [EZOLV]: E9-06 [Motor Rated Current (FLA)]
