operation command must be disabled for a period of time, otherwise the frequency inverter does not
respond to run terminal.
The terminal run command is enabled:
When the inverter is power on or failure, terminals have been effectively run the command, the
inverter will run according to the terminal, start the motor run directly. This situation may lead to the
non expected results or dangerous.

When the inverter power failure, after power on again, whether the inverter automatically start
running. If we need inverter’s automatic running function after power failure, it must satisfy the
restart waiting time set by the P01.24 plus the start delay time set by P01.25, then the inverter
can be start and running.

Acceleration / deceleration curve: select inverter frequency change way in the process of frequency
change in the acceleration / deceleration frequency and so on. If choose linear acceleration /
deceleration, frequency variation of the slope is fixed, change slope is determined by the deceleration
time. If choose the S curve, frequency changes, the slope is always starting from 0 change, when
acceleration / deceleration is completed, the slope is ended with gradually to 0. Due to the continuous
changes of the slope, the motor output is the smallest impact on load device, and is suitable for the
shock, comfort has certain requirements, such as elevator, belt conveyor etc.

○
When the running frequency of the motor is low, the hardware detected counter electromotive force is
very weak, the accuracy of identification of the motor speed is decreased, but through the exciting, we
can get more accurate the motor actual speed.

○
Under the speed tracking mode, the inverter receives the starting signal, and it will track the speed
after delaying the reaction time.
