Firmware Changes High Speed Stall Prevention
The S02 option provides two current limits, compared to one in the
standard drive. Each current limit has definite conditions. The High
Speed Current Limit is used to keep the motor from stalling, while
accelerating toward frequencies above P35 - [Base Frequency]. For
frequencies between base frequency and 150% of base frequency, the
current limit is linearly decreased from P43 - [Low Speed Current Limit]
to P47 - [High Speed Current Limit]. See
Table A .
