Slip compensation function makes output frequency changes according to load
changes, therefore control motor speed at fixed value, as shown in above figure. If
E-044= 0.00
,
slip compensation function is disabled.
*********************************************************
*Note: This function is enabled only when motor power is the same as inverter power.
*********************************************************
E-045 constant voltage control
Constant voltage control function can automatically control output voltage at the
constant value when power voltage changes. Don’t need to adjust V/F characteristic
or change rated voltage of the motor, even if different input voltage areas.
Default is set as 380V
（
3-phase 380V series
）
/220V
（
1-phase 220V series
）
*********************************************************
*Note: this function can’t increase output voltage higher than input power’s voltage.
*********************************************************
E-046 free stop selection
Two stop methods: decel stop and free stop. Free stop is also enabled for external
terminal.
E-046 = 0
：
decel stop
；
E-046 = 1
～
4
：
use external terminals of PI1~PI4 to free stop——if selected
terminal connects with COM, free stop and display “FrEE”
；
if selected
terminal disconnects with COM, decel stop when there are stop signals
；
E-046 = 5
：
free stop and display “FrEE”.
Free stop waiting time is determined by parameter of E-043.
E-047 input permission when emergency stop.
