•The set time here indicates the acceleration/deceleration time between 0 Hz and the maximum
frequency.
Even if a short acceleration/deceleration time is set, the actual time cannot be shorter than the
minimum acceleration/deceleration time that is determined by the mechanical inertia moment and
the motor torque. If you set a time shorter than the minimum time, an overcurrent/overvoltage trip
may occur.
For short-time deceleration, use the regenerative braking unit (optional).
Digital Operator Rotation Direction Selection
Select the direction of motor rotation applied to the RUN command via the Digital Operator.
This is disabled at terminals.
