A (Advanced) Parameter Details; A050 – A056 Cont. & A057 – A068 57
19. A056 = 0023: (Analog input AIN) The multifunction analog terminal AIN = 0023, controlling the output
frequency.
20. A050 = 0024: (Multi-Sequence Control) The Multi-Sequence control is set to 0024 to become the input
terminal for the Auto – Run mode.
Multifunction terminals S1 - S6
and AIN signal scan times
(4mSec )
1.) This function is used to minimize the electrical noise on the digital and analog inputs by sampling the input signal
every 4 mSec. x 1-100 ( 4 to 400 mSec. user selected). If the signal value is the same for the interval time selected
it is treated as a valid value. If the signal changes during the interval time it is treated as noise.
2.) The minimum scan period is 4mS while the maximum is 400mS.
3.) The user can set the scan time interval depending on the noise environment. In general, the noise can be
minimized by increasing scan time interval, however the response to valid signal changes will be slower.
Note: If input AIN is digital, an input voltage level above 8V is treated as ON, and below 2V as OFF.
0000: When Up/Down is used, the preset
frequency is maintained when the inverter
stops, and the UP/Down is unavailable.
0001: When Up/Down is used, the preset
frequency is reset to 0 Hz when the
Inverter stops.
0002: When Up/Down is used, the preset
frequency is Maintained when the inverter
stops, and the UP/Down is available.
1.) A058 = 0000: Upon receiving a Run command the inverter will accelerate to the speed set in parameter A061.
When the Up / Down command is activated the inverter begins to accelerate / decelerate and the inverter will
hold that speed when the Up / Down command removed. When a Stop command is given, the inverter will ramp
stop or stop as determined by the b003. It will store the frequency value at the time when the Stop signal is
activated. The Up / Down function is unavailable when the inverter is stopped. The keypad is available to modify
the preset frequency (A061). If A058 = 0002, the UP/Down function is available When the inverter stops.
2.) A058 = 0001: When the Run terminal is energized, the inverter accelerates from 0 Hz, and the Up / Down function
is same as above. When a Stop command is given, the inverter will ramp stop or stop (determined by b003) to
0 Hz. The next Run command will start from 0 Hz.
Jog and Preset (MFIT) Speed
Setting on Keypad
Set Jog and preset speed by
Keypad
1.) A050 – 056 = 0002 - 0004 (preset speed 1 - 3)
ON: the inverter operates at preset speeds 1 – 8 based on the corresponding frequency output vs. the
terminal input states is shown in the table.
2.) A050 – 056 = 0005 (Jog)
ON: the inverter operates in Jog acceleration time / Jog decelerate time / ON
