When reconnecting or changing the regenerative resistor, observe the table 9-22, Parameter for
Regenerative Resistor, to ensure correct settings of parameters.
1) Regenerative Resistor Type (RGKD)
When absorbing power of the built-in regenerative resistor exceeds the permissible absorbing power
over a long time period (ten seconds to several minutes), abnormal overheating is detected. (Alarm
"H"・RGOH)
- When the built-in regenerative resistor is selected (RGKD = "Built-in R"), its absorbing power can be
monitored by remote operator (Monitor for built-in regenerative resistor absorbing power: RegP・
Mode5-Page17). When the monitor value exceeds the permissible absorbing power, overheating
alarm may be issued. In this case, take appropriate countermeasures, such as reviewing operation
patterns or using an external regenerative resistor.
- When the main circuit power is turned off, the electrolysis capacitor energy inside the Servo Amplifier is
discharged through regenerative resistor. Therefore, in case of frequent repetition of the main circuit
power turn ON and OFF, an alarm may be issued (Main circuit power ON/OFF frequency must be within
10 times/hour and 50 times/day).
- When the control power is turned on, the built-in regenerative resistor absorbing power monitor is set at
Hot Start to protect the built-in regenerative resistor. Therefore, the monitor value will not become "0.0
W" until some time after the control power is turned on.
2) Regenerative Resistor OL Time Select (Func2 bit4)
When the regenerative resistor absorbing power (built-in/external regenerative resistor) is extremely
large, an error will be detected in a short period of time (in hundred msec. to 99 seconds), outputting
regeneration error (alarm "J"・RGOL).
When using a built-in regenerative resistor, correctly set the parameter as follows:
Incorrect settings may hamper proper error detection and cause burnt or damage of
regenerative resistor.
Built-in regenerative resistor may be heated to high temperature, even when no overheat
alarm is issued. Take care not to touch the Servo Amplifier while power is being supplied or
soon after the power turn off (within 30 minutes), otherwise you may be burnt.
