(23) Number of auto restart attempt (Cn-36)
Set the number of auto reset/restart operation. Setting of zero causes no auto
reset/restart operation.
Each time one of OC, OV, OL1, OL2, OL3, OH, UV1 (OC, GF, OV, rr or UV1) fault
occurs, one is added to the number of auto reset/restart operation, and auto
reset/restart operation is performed according to the following procedure.
However, auto reset/restart operation is not performed in the following case:
○
1
When operation not continued at momentary power loss (3rd digit of Sn-11=0)
is specified, UV1 fault is not automatically reset.
○
2
When OC or OV fault occurs due to external fault during deceleration stop or
DC injection braking stop, inverter output is shut off.
The number of auto reset/restart operation is cleared to zero when:
○
1 No fault occurs for 10 minutes or more.
○
2 A fault reset signal is input from control circuit terminals or digital operator.
Auto reset/restart operation
○
1 When a fault is detected, inverter output is shut off for the minimum
baseblock time (Cn-40). During shut off of inverter output, a fault occurring in
the operator is displayed.
○
2 When the minimum baseblock time (Cn-40) elapses, the fault is automatically
reset, and speed search operation is performed with the output frequency at
the time of the fault.
○
3 When the total number of fault exceeds the number of auto restart attempts
(Cn-36), automatic reset is not performed and inverter output is shut off. At
this time, fault contact output is output.
(24) Power loss ride-thru time (Cn-37)
Set in units of 0.1 second. The initial value depends on the inverter capacity
