4.5 Regenerative Resistor Selection
50
Connecting the JUSP-RG08D to the SGDG-01GT/SGDG-04GT
a) A regenerative unit has the following fault detection functions:
• Detecting disconnection in a regenerative resistor
• Detecting faults in a regenerative resistor
• Detecting overvoltage
b) When one of these fault detection functions operates, the internal alarm relay is
actuated. Then the circuit between output terminals C1 and C2 is opened.
c) When an external resistor is used, remove the shorting jumper between Y4 and Y5.
Then, connect the resistor between P/Y3 and Y4.
d) The resistance value of the external resistor should be 50
Ω min.
