6.5 Change Frequency Unit from Hz to rpm
Enter the number of motor poles in 16-03 to change the display units from Hz to rpm.
16-03
Display unit
Range
0: Display unit is Hz (Resolution is 0.01Hz)
1: Display unit is % (Resolution is 0.01%)
2: Rpm display; motor rotation speed is set by the control modes to select IM (02-07)/ PM
(22-03) motor poles to calculate
3~39: Reserved
40~9999: 100% is XXXX with no decimals (integer only)
10001~19999: 100% is XXX.X with 1 decimal
20001~29999: 100% is XX.XX with 2 decimals
30001~39999: 100% is X.XXX with 3 decimals
Example: Motor poles 4, 02-07 or 22-03 = 4.
