4-04:Custom Units (Line Speed) Value : 0-9999
The max preset line value of 4-04 is equal to the rated frequency (0-05) of the motor. For
instance, given line speed 1800 is equal to display 900 when output is 30Hz while the operation
frequency is 60Hz.
4-05 : Custom Units (Line Speed) Display Mode
0000:Drive Output Frequency is Displayed
0001:Line Speed is Displayed in Integer (xxxx)
0002:Line Speed is Displayed with One Decimal Place (xxx.x)
0003:Line Speed is Displayed with Two Decimal Places (xx.xx)
0004:Line Speed is Displayed with Three Decimal Places (x.xxx)
The preset frequency is displayed as the inverter stops while the operation line speed is displayed as
the inverter is running.
4-06:PID Feedback Display 0000:Disabled
0001:Enable
Keypad displays PID feedback value :
Parameter 5-05=20 (That is, S6 is set as the PID feedback analog terminal, refer to PID),
11-0=1(PID is enabled), and 4-06=1(Display S6 as PID analog feedback value 0~100, the formula as
follow:)
If feedback signal is 0~10V, (12-6=0000), keypad display value = (S6/10V)*100
If feedback Signal is 4~20mA, (12-6=0001), keypad display value = (S6/20mA)*100
※Note: Please press DSP Key to switch between the output frequency and PID feedback value.
※Note: The inverter displays XXXF as Running, while XXXr as Stop.
