Connecting A Regenerative Unit (Jusp−Rg08C Type) - YASKAWA SGM series User Manual

5) Connecting a Regenerative Unit (JUSP−RG08C type)
Single-phase
200-230 VAC or
100-115 VAC
a) A regenerative unit has the following fault detection functions:
• Detecting disconnection in a regenerative resistor
• Detecting faults in a regenerative transistor
• Detecting overvoltage
b) When one of these fault detection functions operates, the internal alarm relay is actu-
ated. 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 50Ω min.
