Command Command input device’s Analog 3 input Analog1 voltage > Analog1 Fault Max Cycle KSI. Hold then 1 = Stop.
Analog1 (pin 8) is out of range. or Analog1 voltage < Analog1 Fault Min. Shutdown.
Out of Range The fault is checked only if Command
Input Device = 0, 2, or 3.
42 1
Command Command input device’s Analog 3 input Analog3 voltage > Analog3 Fault Max Cycle KSI. Hold then 1 = Stop.
Analog3 (pin 19) is out of range. or Analog3 voltage < Analog3 Fault Min. Shutdown.
Out of Range The fault is checked only if Command
Input Device = 0, 2, or 3.
43 1 Feedback
Position feedback device’s Analog 5 input Analog5 voltage > Analog5 Fault Max Cycle KSI. Hold then 1 = Stop.
Analog5 (pin 16) is out of range. or Analog5 voltage < Analog5 Fault Min. Shutdown.
Out of Range The fault is checked only if Position
Feedback Device = 0, 2, or 3.
44 1 Feedback
Position feedback device’s Analog 6 input Analog6 voltage > Analog6 Fault Max Cycle KSI. Hold then 1 = Stop.
Analog6 (pin 17) is out of range. or Analog6 voltage < Analog6 Fault Min. Shutdown.
Out of Range The fault is checked only if Position
Feedback Device = 0, 2, or 3.
