Appendix C Special Function Parameter Settings
Some parameters must be changed based on the field application.
• P113: Flying Start - Initial Output Voltage Percentage (%)
• P114: Flying Start - Current Comparison Delay For Motor Speed Search
• P115: Flying Start - Current Threshold For Successful Motor Speed
Search
• P416: Enable Flying Start mode
• P417: Flying Start Motor Speed Search Timeout (s)
• P438: Flying Start Current Compensation Threshold
• P457: Flying Start Voltage Recovery Time (s) (Low Speed Region)
• P459: Flying Start Voltage Recovery Time (s) (High Speed Region)
• P463: Flying Start Low/High Speed Regions Boundary (%)
If the drive cannot search the speed in the field, increase P417 to decrease the
search step and improve the accuracy; or increase P113 and decrease P115 to
improve the accuracy. If there was any noise during the restore stage, increase
P457 or P459. P463 does not need to be changed.
Search from Maximum Frequency to implement AC mode to VF mode.
Restart the Drive Relevant parameter: P461, P462, P465
Description: these parameters use the auto-restart feature after a system fault.
Instruction: if P461 is enabled (P461=1), the drive will restart at once when
system fault occurs.
If there is something wrong with a Power Module, it will wait for P465 before
restarting. If a fault happens twice during the Fault Reset Timeout (P462), the
drive will trip.
IMPORTANT P416 enables Flying Start Selection. If the Flying Start is not successful, change
the other parameters listed accordingly. Otherwise, these parameters do not
normally need to be changed.
IMPORTANT If restart feature was enabled, the second mode of flying start feature must be
enabled.
