Important
• Use this parameter with the motor connected.
• When the inverter is used with a load that fluctuates considerably, it may fail to adjust the
acceleration or deceleration time in time, and therefore may be tripped.
• When using the optional braking resistor or braking unit, do not set <AU1: Automatic Acc/Dec>
to "1". Otherwise, braking resistor overload may occur during deceleration.
Memo
• When the acceleration/deceleration time is automatically set, the acceleration/deceleration time
is always changed according to the load. For machinery that requires constant acceleration/
deceleration time, accelerate or decelerate with the setting time of <ACC: Acceleration time 1>
and <dEC: Deceleration time 1> instead of using this function. For details, refer to [5. 2. 4].
