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
