1<\/strong>. Error code definition
Open phase
2<\/strong>. Error definition and error detection method
An open phase of the power supply (L1 phase, N phase) was detected at power on.
The L3 phase current is outside of the specified range.
When an open phase is detected (L3-phase or N-phase in the power supply) is detected at the start of operation.
The open phase of the power supply may not always be detected if a power voltage from another circuit is applied.
3<\/strong>. Cause, check method and remedy
Cause Check method and remedy
(1) Power supply problem
Open phase voltage of the power supply
Power supply voltage drop
Check the input voltage to the power supply terminal block TB1.
Possible open phase in the power-supply due to improper pow\u0002er-supply wiring. (Refer to item (6) in section [6-1 Read before
Test Run].)
(2) Noise filter problem
Coil problem
Circuit board failure
Check the coil connections.
Check for coil burnout.
(3) Wiring failure Check the wiring between CN5 on the noise filter and CNAC on
the control board.
Check the wiring between CN3 on the noise filter and CN110 on
the control board.
(4) Blown fuse Check for a blown fuse (F001) on the control board.
\u2192If a blown fuse is found, check for a short-circuiting or earth fault
of the actuator.
Check for a blown fuse (F3) on the noise filter.
\u2192If a blown fuse is found, check for a short-circuiting or earth fault
of the actuator.
(5) Control board failure Replace the control board if none of the above is causing the
problem.<\/p>\n","protected":false},"excerpt":{"rendered":"
