Chapter 6 - Parameter Description [DRV]
6-4
The speed factor for operation below 20Hz is:
Speed_Factor = (1.5 %/Hz * drive frequency (Hz) + 65%) / 100%
[Load Current Derating Curve]
[Forced-cool]
is for a motor that uses a separate motor
to power a cooling fan or an inverter duty motor that
does not need o be derated at lower speeds. As the
motor speed changes, the cooling affect does not
change. The value set in DRV-08 [Electronic thermal
level for continuous] is applied regardless of operating
frequency. The Speed Factor for a forced cooled motor
is always 1.0.
DRV-10: Output Current
This parameter displays the average three-phase output
current.
DRV-11 DC Link Voltage
This parameter displays the DC link (DC bus) voltage.
DRV-12: User Display Selection
This parameter displays the value of the parameter
selected in AFN-81 [User Display].
DRV-13: Present Trip Display
This parameter displays the present fault (trip) status of
the drive. Use the
PROG
,
▲ and ▼
keys before
pressing the
RESET
key to check the fault log content.
Output frequency, output current, and the mode of
operation when the fault occurred are displayed. Press
the
ENTER
key to exit. The fault content will be
stored in AFN-01 to AFN-05 after the
RESET
key is
pressed.
For more detail, refer to Chapter 7. Troubleshooting
and Maintenance.
