03-27=0:
When the run command is removed, the External UP/DOWN frequency reference from before deceleration is
stored. The next time the run command is applied, the output frequency will ramp up to the previously stored frequency
reference. Adjustments to frequency reference can only be made after previously stored reference is reached.
03-27=1:
When the run command is removed, the External UP/DOWN frequency reference command is cleared (set to
0). The next time the run command is applied, the output frequency will start at 0.
03-27=2:
UP/DOWN command is active when run command is not active.
03-27=3:
When the run command is removed, the External UP/DOWN frequnecy reference from before deceleration is
stored. When run command is applied, the output frequency will ramp up to the previously stored frequency reference.
Adjustments to frequency reference can be made at any time during run, but before the set frequency is reached.

There are two ways to use the pulse input:
1.Pulse Frequency (Frequency reference = pulse frequency divided by 03-27 x max. frequency (01-02)
2.PWM (Frequency reference = pulse duty cycle (%) x max. frequency (01-02)
Note
: The time deviation in PWM mode is ±12.5%. If pulse PWM is outside of the deviation range the pulse input is
not active.
* Refer to figure below for the pulse input specification.
