You can also use H1-xx = 83 to 85 [Dedicated Multi-Setpoint YA-02 to YA-04] to select the digital setpoints as an
alternative to 3E and 3F . Table 5.68 shows which Setpoint is active as specified by the Dedicated Multi-Setpoint
Selections.

Note:
•
For all sources, you can change the value of setpoint with other functions, for example Sleep Boost function.
• If you set a minimum of one PID Setpoint Selection ( H1-xx = 3E or 3F ) and a minimum one Alternate Multi-Setpoint Selection ( H1-xx =
83, 84, or 85 ), the drive will detect an oPE03 [Multi-Function Input Setting Err] .
System Feedback Monitor
Monitor U1-61 [System Feedback] shows the currently set PID Feedback from these four sources:
•
H3-xx = B [MFAI Function Selection = PID Feedback]
•
H3-xx = 24 [PID Feedback Backup]
•
H3-xx= 2D [Differential Level Source]
Monitor U1-61 will show the PID Feedback when the PID is disabled.
Note:
The System Feedback ignores these feedback sources, which are only shown in U5-01 [PID Feedback] :
• MEMOBUS Register 15FF (Hex.) [Memobus PID Feedback]
•
H3-xx = 2B [Emergency Override PID Feedback]
•
MEMOBUS Register 3A95 (Hex.) [Emergency Override PID Feedback]
Automatic Setpoint Display Switch-over when in PID Mode
When the drive is in PID mode, the Home screen will change to show U5-99 [Setpoint] . It will not show U1-01
[Frequency Reference] .
When b1-01 = 0 [Frequency Reference Selection 1 = Keypad] and you push on the Home screen, the keypad will
show YA-01 , YA-02 , YA-03 , or YA-04 and let you change it.
