Suggestions below as to motor parameters to check. Make sure the motor is wired for 220V.
00-00 SLV mode = 1
Group 02 parameters should be:
02-01 Motor rated current = 4.0A
02-03 Motor rated speed = 1150
02-04 Motor rated voltage = 220V
02-05 Motor rated power = 0.75 kW
02-06 Motor rated frequency = 60 Hz
set 02-07 to 1 and run auto tuning
I would be conservative with this motor given the age and the insulation rating, so 60 or 70 Hz maximum and a carrier frequency in the 6-8 kHz range. Usable speed range is probably 20-60 Hz.
I went through the 54 functions today and recorded them. Almost everything is default values. External command source is correct for using the drum switch. Frequency settings are for 60hz, voltage is set for 220V. Didn't see anything listed as "SLV".
My motor settings show:
motor current = 3.4A, motor voltage = 220V, motor power= 0.8kw, motor frequency= 60hz
The motor speed is a little confusing to me, my setting is 17.0 The manual has this value range notation: "0-120 (* 100 rpm) * 8"
If I did the calculation correctly my motor speed rivals a jet engine, obviously I am not doing it correctly. I don't remember putting these values in but that was 15 years ago.
One interesting thing that I did find is the last function is "Latest 3 fault records", the display shows: "LUC". I didn't find that code listed in the manual. Tomorrow I will look at that function again and see if I can find more info.
I agree on the usable speed range, my experience has been that 20hz is the lowest, I usually work with 40-60hz or change the drive belt position.
