8.36 DIx_Select = 36, TMIC, start Astable Timer/Counter
If the input TMIC is OFF, the output TMOC is always
under ON state.
When the TMIC is ON, then the TMOC will start the
Astable ON/OFF cycle.
The period of time for one ON/OFF cycle is determined
by Pr.71. (Refer to Sec.8.94)
The duty cycle is 50%.
If TMOC assigned by DOx(92), the TMOC output will
remain OFF, when TMIC is OFF.
8.37 DIx_Select = 37~47, reserve
8.48 DIx_Select = 48, Speed Hold
When DIx(48) is ON, the inverter will stop ramp up or ramp down, and hold on present running speed.
If DIx(48) change to OFF, the inverter will resume ramp up or ramp down.
8.49 DIx_Select = 49, reserve
8.50 DIx_Select = 50, PID Enable
8.51 DIx_Select = 51, PID Hold
8.52 DIx_Select = 52, PID Clear
8.53 DIx_Select = 53, PID Preset
8.54 DIx_Select = 54, PID Bias Enable
8.55 DIx_Select = 55, PID Boost Enable
Refer to Appendix A
8.56 DIx_Select = 56~68, reserve
8.69 DC-BRAKE1
8.70 DC-BRAKE2
8.71 DC-BRAKE3
When set DIx(69 or 70 or 71) ON, the inverter will start injecting a continuous DC current into the motor winding.
Under this application, AI1, AI2 or AI3 are used to define the level of the injection current respectively.
The actual DC output voltage level is defined by Pr.06*Aix.
8.72 SENSOR-LESS Mode Change (for PDAN/PDA series only)
DIx(72) is used to toggle the operating mode between SENSOR-LESS and NON-SENSOR-LESS externally.
If Pr.67=1, and DIx(72)=ON, mode will change from
Non-Sensor-Less
to
Sensor-Less
.
If Pr.67=3, and DIx(72)=ON, mode will change from
Sensor-Less
to
Non-Sensor-Less
.
8.73 RUN function
8.74 REV function
Any digital input terminal assigned as DIx(73) will function as RUN terminal input.
Any digital input terminal assigned as DIx(74) will function as REV terminal input.
Refer to section 6 for detail RUN and REV terminal function.
8.75 Power Control Input Selection (for PDAN/PDA series only)
This function is only available under Pr.67=4, the
Power Control
mode.
When DIx(75) is ON, AI2 is selected in order to modify the
POWER-LIMIT-CURVE
.
Otherwise, if DIx(75) is OFF, or not any DIx(75) is assigned, AI3 is selected.
Refer to section 4.3.4.
8.76 FORWARD INHIBIT (for PDAN series only)
8.77 REVERSE INHIBIT (for PDAN series only)
If DIx(76)=ON, Forward Run is inhibited.
If DIx(77)=ON, Reverse Run is inhibited.
8.78 DIx_Select = 79, Increase the Panel Set frequency
8.78 DIx_Select = 79, Decrease the Panel Set frequency
While using Panel Set frequency as speed command (Pr.40=8),
if DIx(78)=ON, can increase the Panel Set frequency, and
if DIx(79)=ON, can decrease the Panel Set frequency.
8.80 DIx_Select = 80~83, 16 STEP-Speed select
DIx(80)~DIx(83) are used to assign 16-step frequency.
If DIx(2)~DIx(5) are all OFF, (no JOG, SPD1, SPD2, SPD3 function)
and if any of DIx(80)~DIx(83) is ON, then the set speed is:
Set Frequency = DIx(83)*Pr.27 + DIx(82)*Pr.24 + DIx(81)*Pr.21 + DIx(80)*Pr.19
