P12.0 – Analog Input Type Hold. Reg. Type:
Description: Read/Write
Defines the function of the Analog Input (AI).
Range: Modbus Decimal Value: Default (decimal):
• 0–10V : The input voltage varies from 0 to 10V.
• 4–20mA : The input varies from 4 to 20mA.
• 0
• 1

P12.1 – Analog Input: Select Function Hold. Reg. Type:
Description: Read/Write
Allows the Analog Input to be mapped to different functions. The selected function will change in
proportion with the input.
Range: Modbus Decimal Value: Default (decimal):
• Off
• Current Limit Start
• Current Shearpin
• Current Overload
• 0
• 420
• 431

Example:
Current
Limit Start
420
AI signal controls P3.3 Start Current Limit Level. Ex: Water pumping
system with high head; nearly vertical lift. AI signal keeps P3.3 low
at start to slowly rotate motor to control flow until height is reached,
then AI signal increases P3.3 to allow motor to accelerate to full speed.
Usually PLC control.
Current
Shearpin
431
AI signal controls P5.6 Shearpin Trip Current. Ex: Applications such
as opening and closing sluice gates or doors, which require different
running current limits for opening vs. closing. AI signal changes P5.6
as needed, usually via PLC control. P5.5 Shearpin Trip is turned OFF
when P5.6 level is reached; however an output should be used to stop
the motor via a relay in the motor stop circuit.
Current
Overload
441
AI signal controls P5.9 Overload Level. Ex: Motor testing. AI signal
changes P5.8 as needed to test different motors.
