Multi-function Compact Inverter 3G3MX2-EV2 User’s Manual (I666-E1)
5-8-2 Restart after Resetting
•
In the Reset Restart Selection (C103), select the restart method after trip reset is executed.
However, when the Reset Selection (C102) is set to 03 (Trip reset only), the inverter restarts from 0
Hz independently of the C103 setting.
•
To reset via the control circuit terminal block, set the Multi-function Input 1 to 7 Selection (C001 to
C007) to 18 (RS: Reset).
•
After the reset signal is input and the motor falls in a free-run state, a large residual voltage remains
between motor terminals.
If the inverter restarts the output in this condition, an overcurrent may occur.
To avoid this, set the Restart Standby Time (b003) to a large value.
•
When the Reset Restart Selection (C103) is set to 00 (0-Hz restart), the inverter ignores the Restart
Standby Time (b003) and restarts from 0 Hz.
•
When Reset Restart Selection (C103) is set to 01 (Frequency pull-in restart at shutoff), frequency
pull-in restart will be executed also when the power supply is cycled.
