[Al. 130_Regenerative Error 2] - Mitsubishi Electric MR-J5-G Series User Manual

[AL. 130_Regenerative error 2]

• The regenerative power exceeds the permissible regenerative power of the built-in regenerative resistor or regenerative
option.
• The regenerative transistor in the servo amplifier has malfunctioned.
[AL. 130.1_Regenerative heat error]
Cause
1.
The settings of the regenerative resistor
(regenerative option) are incorrect.
2.
The regenerative resistor (regenerative option)
is not connected.
3.
The regenerative resistor (regenerative option)
and the servo amplifier are connected in a
wrong combination.
4.
The power supply voltage is too high.
5.
The regenerative power is too large.

1.3 Handling methods for alarms/warnings
Check/action method
Refer to "Regenerative option" in the following manual.
MR-J5 User's Manual (Hardware)
Refer to "Regenerative option" in the following manual.
MR-J5 User's Manual (Hardware)
Check the combination of the regenerative resistor (regenerative option) and
the servo amplifier.
Refer to "Regenerative option" in the following manual.
MR-J5 User's Manual (Hardware)
Check if the voltage of the input power supply exceeds the upper limit of the
permissible voltage. If it exceeds the limit, lower the power supply voltage.
200 V class: 264 V AC
400 V class: 528 V AC
Check whether the regenerative load ratio exceeds the upper limit value when
the alarm occurs.
Take the corrective actions as follows.
• Reduce the frequency of positioning.
• Set a longer deceleration time constant.
• Reduce the load.
• Use a regenerative option if it is not being used.
[WG]
• Ensure that each axis does not decelerate simultaneously.
