* The ST (standby signal) function is not assigned to any terminal.
If necessary, assign this function to an unassigned terminal,
using the multi-function programmable terminal function.
★H set to  (): The auto-restart function is activated when R(ST)-CC is short-circuited
after they have been opened.
Notes
• A waiting time between 200 and 300 msec is preset to allow the residual voltage in the
motor to come down to a specified level during restart. For this reason, the start-up takes
more time than usual.
• Use this function when operating a system with one inverter connected with one motor.
This function may not be performed properly in a system with one inverter connected
with multiple motors.
Application to a crane or hoist
The crane or hoist might allow the load to move downward during the time elapsed before
the motor starts after receiving an operation starting command. When applying the
inverter to such a lifting gear, set the auto-restart control selection parameter to 0
(disabled) and avoid using the retry function.
