C5 ASR Tuning
The Automatic Speed Regulator (ASR) provides closed loop motor speed control so
that optimum performance during changes in motor speed or load can be achieved
.
Setting Range: 0.00 to 300.00
Factory Default: 5.00
The ASR proportional gain 1 adjusts the speed in response to the speed deviation
signal. Speed response increases as the proportional gain is increased. However,
the load may become unstable if the ASR proportional gain is set too high.
Setting Range: 0.000 to 10.000s
Factory Default: 0.500s
The ASR integral time 1 adjusts the inverter’s response time to changes in load.
Response increases as the integral time is decreased. However, the load may
become unstable if the ASR integral time is set too low.
Setting Range: 0.00 to 300.00
Factory Default: 5.00
The ASR proportional gain 2 is an additional proportional gain adjustment that can be
enabled by a multi-function contact input (H1-XX = “77”).
