This parameter determines rotating direction of programming operation 5-00 to 5-06 as well as all step running of the
master speed.
Setting method: Operation direction setting is in binary 8 bit, and only input this parameter after it is transferred into
decimal value.

Time setting for 8 parameters above refers to time which fits each step of auto-programming operation. Max of the
parameter shall be 65500 sec, and display shall be d 65.5.
Special description: When this parameter is set to d0 (0 sec), it means that operation for this step is omitted and
operation of next step shall be performed automatically. This means that although 8 steps are provided by the
inverter, users can minify it into 2 steps according to specific requirements, this function can be realized by set time
of the step which shall be omitted to d0 (0 sec).

When deceleration is performed, back-up energy may be generated in motor drive due to inertia of motor load, and
DC side voltage may rise to max value. Thus, when over voltage stall prevention is started, over voltage at DC side
shall be detected, and deceleration shall be interrupted (output frequency shall be kept), which will not be performed
again by inverter until voltage is below setting value.
