Horse Power Limiter & Anti Stall Mode with Reverse
Selection from Menu -> Control Logic -> Anti-Stall Mode with Reverse
The PowerLine controller has a new useful
function that combines Anti-stall with a
reverse feature.
This feature will allow the user to set up the
anti-stall as normal with ‘SLOW’ and
‘STOP’ limits, with the difference being that
if the monitored RPM reaches the ‘STOP’
limit, the controller will turn the PWM% A
output fully off, then turn the PWM% B on
to offer a reverse feature.
The ramps used for the PWM% A and
PWM% B are set in the process setup
window as shown here.
IMPORTANT NOTE: Reverse feature ON/OFF setting
The reverse feature is turned OFF by setting the ‘Auto Reverse Time’ to 0 (ZERO) seconds.
The auto reverse feature is turned ON if there is any time entered in the ‘Auto Reverse Time’ box.
The minimum reverse time is 0.5 seconds while the max is ~85 seconds.
