This parameter defines the behavior of the drive if there is a phase loss on the output of the drive.
P6.45~P6.48 are parameters for output phase loss. When the motor’s current is less than the
current level in P6.47 and is longer than the time set in P6.46, the result will be seen as output
phase loss. An error message OPHL will be shown on the keypad.
•
When P6.45≠3, OPhL Detection is enabled.
•
When P6�45=3, all OPhL parameters are disabled (P6�45~P6�48)�
Related parameters: P6.45~P6.48; refer to further information following P6.48 (page 4–153).
Type Hex Addr Dec Addr
P6.46 Output Phase Loss Detection time
R/W 062E 41583
Range/Units (Format: 16-bit unsigned) Default
0�000~65�535 sec
0�500
This setting will determine the time lapsed from when an output phase loss is detected to when
the action selection is initiated in P6.45.
Related parameters: P6.45~P6.48; refer to further information following P6.48 (page 4–153).
Type Hex Addr Dec Addr
P6.47 Output Phase Loss Current Detection Level
R/W 062F 41584
Range/Units (Format: 16-bit unsigned) Default
0�00~100�00% (of max current)
1�00
This parameter sets the Level of Detection for OPhL monitoring.
Related parameters: P6.45~P6.48; refer to further information following P6.48 (page 4–153).
Type Hex Addr Dec Addr
P6.48 Output Phase Loss DC Injection Brake (DCI) Time
R/W 0630 41585
Range/Units (Format: 16-bit unsigned) Default
0�000~65�535 sec
0�000
When this parameter is 0, the OPhL DCI Brake function is disabled. When P6.48 >0, the DCI brake
current will be monitored against (20)x(P6.47 level). The drive will trigger an OPhL fault If any
phase falls below the (20)x(P6.47 level) for a time period of (P6.48)/(2).
Related parameters: P6.45~P6.48; refer to further information following P6.48 (page 4–153).
