Range/Units (Format: 16-bit binary)
0: no Function
1: Frequency Command/PID Setpoint REMOTE*
2: Frequency Command/PID Setpoint LOCAL*
3: Frequency Command/PID Setpoint REMOTE & LOCAL*
4: reserved
5: PID Feedback Signal*
6: PTC Thermistor Input Value*
7: PID Setpoint Offset*
8~10: reserved
11: PT100 RTD Input Value*
(*1,2,3,5,7) PID functions 1, 2, 3, 5 & 7: Refer to Parameter Group 7 to define the analog inputs for
(*6) PTC Thermistor Input Value: Refer to P6.39~P6.40. When the input goes above the value set in
P6.40, the action in P6.39 will occur. The PTC Warning and/or Fault will be oH3: Motor Over
Heat. (For Option 6 to work, P6.43 PT Drop Freq must be > 0.)
(*11) RTD (PT100) Thermistor Input Value: Refer to P6.41~P6.44. The PT100 Warning and/or Fault
will also be oH3: Motor Over Heat. (For Option 11 to work, P6.43 PT100 Drop Frequency must
be > 0.)
These three parameters, P4.02~P4.04, assign functions for the three analog inputs, AI1~AI3.
Please note that parameter settings 1, 2, and 3 can assign any of the analog inputs to be
Frequency Command/PID Setpoint for REMOTE mode only (#1), for LOCAL mode only (#2), or for
both REMOTE and LOCAL modes (#3).
Example: An application requires analog input control from a PLC while the process is running,
but speed control from a local potentiometer is needed for setup/jogging.
• Set both P4�00 (REMOTE) AND P4�01 (LOCAL) = 2 (Analog Input)�
• Wire the PLC signal to AI1, and set P4�02 = 1 (AI1 = Freq Command in REMOTE)�
• Wire the potentiometer to AI2, and set P4�03 = 2 (AI2 = Freq Command in LOCAL)�
With these settings and control wiring, the system will respond to the PLC signal when the
REMOTE button is pressed, and will follow the potentiometer when the LOCAL button is pressed.
Note: If multiple registers are selected for the same function, the priority (which one wins) is
AI1>AI2>AI3.
Example: If a "1" is entered into all 3 of these parameters, AI1 will be the active "Frequency
Command/PID Setpoint REMOTE".
Note: AI3 is always ±10V.
Related parameters: P0.04 (Drive Max Output Frequency), P4.00~P4.01 (Remote/Local Source of
Freq Command), P6.39~P6.44 (for details on setting up RTD or PTC), P7.xx (PID)
