41 Multi-position
Attained
User can set any three multi-function input terminals to 41. The
current position action status of these three terminals will be
outputted. Example: if setting Pr.02-11, Pr.02-12 and Pr.02-13
to 41 and only the multi-position of the second point has been
done. Therefore, current status are RA (OFF), MRA (ON) and
MO1 (OFF). In this way, their status is 010.
42 Crane
Function
This function should be used with Pr.02-31, Pr.02-32 and
Pr.02-33.
Active when setting Pr.07-16=Pr.02-33 and Fcmd > Pr.02-33
and output current > Pr.02-32 and Time > Pr.02-31.
The example of the crane application is in the following for
your reference.
43
Motor Zero-speed
Output (Pr.02-43)
Active when motor actual speed is less than Pr.02-43.
44
Max. Reel Diameter
Attained
Active when the reel diameter is equal to Pr.08-43 in the
tension control mode.
45
Empty Reel Diameter
Attained
Active when the reel diameter is equal to Pr.08-44 in the
tension control mode.
46
Broken Belt Detection
In the tension control mode, the broken belt occurs when 1.
line speed is higher than Pr.08-61, 2. the error of reel diameter
exceeds Pr.08-61, 3. detection time exceeds Pr.08-62
47
Break Release at Stop
When drive stops, the corresponding multi-function terminal
will be ON if the frequency is less than Pr.02-33. After it is ON,
it will be OFF when brake delay time exceeds Pr.02-31.

Error PID Feedback of
Tension
In the tension control mode, when the error between PID target
value and PID feedback exceeds Pr.08-63 and allowance error
detection time of tension PID feedback exceeds Pr.08-64,
please refer to Pr. 08-64 for error treatment of tension PID
feedback.
