Application Functions
6-8
6.3.3 Sequence at main power OFF

The operation sequence at the main power supply OFF is changed with combination, such as 6007h/6807h
(Abort connection option code), Pr5.07 (main power off sequence), and PSM Pr.02 (main power off detection
time).

Basically, the deceleration function defined by CoE (CiA402) is valid until the deceleration function defined by
servo (MINAS-A6) side is activated by detecting the main power supply OFF (between L1, L2, and L3) of the
power supply module.
-
When "No action" is set by 6007h/6807h = 0, the CoE (CiA402) deceleration function does not operate,
and the deceleration function on the servo (MINAS A6) side operates.
-
When the main power DC-bus voltage decreases, Err13.0 (Main power undervoltage protection [PN])
occurs with the highest priority, causing the operation in accordance with Pr5.10 (Sequence at alarm).

This section explains deceleration function on the servo (MINAS A6) side.
Please refer to "TECHNICAL REFERENCE EtherCAT Communication Specification (SX-DSV03456)"
for details of deceleration function on the CoE (CiA402) side.

off 0 to 3 - Select LV trip or servo OFF upon occurrence of main AC power
alarm.
Setup the condition to detect main AC power OFF alarm when the
main AC power is kept interrupted for a time longer than the time
set by PSM Pr.02.
bit0: 0: The servo off according to the setting of 6007h/6807h
(Abort connection option code) or Pr5.07.
1: Trip with Err 13.1 Main power undervoltage protection.
(Note 1 )
bit1: 0: Detect main AC power OFF alarm only when servo is in
ON state.
1: Always detect main AC power OFF alarm.
