FAIL : the measurement sequence was interrupted, i.e. the inspection
switch was release prematurely, or the controller dropped the
enabled signal to the drive. Verify if the controller is droping the
signal by first setting LF.3 to conf and try again. If the controller
still drops the enable and the motor contactor, the problem lies in
the controller.
E.ccd: the measurement of one of the motor paramters was not
possible. Repeat the process and not what code is display just before
the error occurs. Then contact the manufacture for assistance. In
some cases the error can be avoided by preadjusting some motor
data.
It is necessary to enter the machine data such that the drive can establish
the relationship between linear travel, ft/min and rotary speed in rpm at
the motor.
Enter the job contract speed in parameter LF.20.
Then enter the sheave diameter in LF.21. If this value is not known, it
can be measured with a tape measure. Some sheave manufacturers
will show the "Minimum Groove Diameter" on a plate attached to the
sheave. This is the diameter to the bottom of the groove, which is normally
about one inch smaller than the actual diameter at which the rope lies.
Therefore, when this dimension is provided, add one inch to it and enter
that value into LF.21.
LF.22 is the machine gear ratio. It is often listed on the machine as a ratio
of gear teeth such as 55:2. In this case divide the ratio (55/2 = 27.5) and
enter the value. If the ratio is not known, skip ahead to LF.23 and then
see LF.25 for an estimated gear ratio which can be entered into LF.22.
Remember for gearless jobs the gear ratio is 1.00.
LF.23 is the roping ratio. For most geared applications it is 1:1. For
gearless application the rope ratio is typically 2 but can be higher.
LF.24 is the car rated capacity in lbs.
LF.25 is the estimated gear ratio. If the gear ratio is not known, take the
value from LF.25 and enter it into LF.22.
Set up for the machine is complete!
