The operation to perform when the main circuit power is turned OFF while the Servo is ON can be set
using the Undervoltage Error Selection (3508 hex). 3508 hex = 0: Moves to a state where the main circuit
power supply is turned OFF and stops according to the setting of the Shutdown option code (605B hex).
3508 hex =1: Moves to an error processing state and stops according to the setting of the Fault reaction
option code (605E hex).
State is controlled by combining the bits in the Controlword (6040 hex) as shown in the following table.
*1
The state automatically moves to Operation enabled state after Servo Ready (Switched on) state.
*2
Quick stop commands are not supported. Even if a quick stop command is received, it will be ignored.
*3
Bit 7: Operation when Fault reset bit turns ON.
*4
When an error reset is executed with bit 7, set the bit back to 0 before giving the next command.

Fault state
•
Errors are reset and the Servo Drive returns to its initialized state (Switch on disabled).
•
Check the Statusword (6041 hex) bit 7 (Warning) and reset it if an error has occurred.
State other
than Fault state
•
Check the Statusword (6041 hex) bit 7 (Warning) and reset it if an error has occurred.
•
The state will change according to command bits 0 to 3.
