Chapter 12 Description of Parameter Settings
MH300
Dwell Time at Acceleration
Default: 0.00
Settings 0.00–600.00 sec.
Dwell Time at Deceleration
Default: 0.00
Settings 0.00–600.00 sec.
Dwell Frequency at Acceleration
Default: 0.00
Settings 0.00–599.00 Hz
Dwell Frequency at Deceleration
Default: 0.00
Settings 0.00–599.00 Hz
In heavy load situations, the Dwell temporarily maintains stable output frequency. Use this
parameter for cranes, elevators, and so on.
When the load is heavier, use Pr.07-15–Pr.07-18 to avoid ov or oc protection.
Default: 3
Settings 0: Fan is always ON
1: Fan is OFF after the AC motor drive stops for one minute.
2: Fan is ON when AC motor drive runs; fan is OFF when AC motor drive
stops.
3: Fan turns ON when the temperature (IGBT) reaches around 60
o
C
Use this parameter to control the fan.
0: Fan runs immediately when the drive power is turned ON.
1: Fan runs when AC motor drive runs. One minute after AC motor drive stops, the fan is OFF.
2: Fan runs when AC motor drive runs and stops immediately when AC motor drive stops.
3: Fan is ON when the IGBT or capacitance temperature is higher than 60
o
C.
Fan is OFF when the the IGBT and capacitance temperature are both lower than 40
o
C, and the
drive stops running.
