Chapter 2 Parameter Descriptions
Pre-charge DC Bus Threshold
Linear Number: P105
Default Value: 80%
Minimum Value: 0%
Maximum Value: 100%
Access Level: R&D
Read/Write: Read/Write
Modify Level: Online/Offline
This parameter sets the threshold for the pre-charge DC bus voltage. The
duration of the pre-charge is the time taken for the DC bus voltage to reach the
set threshold. When DC bus voltage reaches this threshold is one of the
conditions to determine that pre-charging is completed.
Pre-charge Max Time
Linear Number: P118
Default Value: 6 s
Minimum Value: 2 s
Maximum Value: 20 s
Access Level: Setup, R&D
Read/Write: Read/Write
Modify Level: Online/Offline
This parameter sets the maximum time for pre-charging. If the pre-charge
duration exceeds this time, it is considered pre-charge process overtime.
Pre-charge Min Repeat Interval
Linear Number: P119
Default Value: 5 min
Minimum Value: 5 min
Maximum Value: 60 min
Access Level: Setup, R&D
Read/Write: Read/Write
Modify Level: Online/Offline
This parameter sets the minimum repeat interval time for pre-charging. After a
pre-charge is complete, the timer starts. If another pre-charge occurs within the
set time, it is considered pre-charge overtime.
Pre-charge Primary Voltage Threshold
Linear Number: P120
Default Value: 80%
Minimum Value: 0%
Maximum Value: 100%
Access Level: R&D
Read/Write: Read/Write
Modify Level: Online/Offline
This parameter sets the threshold for the pre-charge primary voltage. When line
side voltage reaches this threshold is one of the conditions to determine that pre-
charging is completed.
