The display may then issue a warning to indicate the maximum ‘FORWARD SPEED’
attainable for the selected rate.
If the machine has not been calibrated ignore these warnings until calibration is complete.
To maintain the requested drilling rate, the metering motors speed up in proportion to the
forward speed of the machine. The metering motors are protected by a speed and current
limit. If the forward speed exceeds the maximum advised, the metering motors will not be
able to deliver enough product. At normal rates and speeds this limit is never found. Note that
the indicated maximum is for the lowest of the 2 products shown.
