②
GSK controller Electronic component lifetime warning
If even one of the following warning conditions occurs, the output signal to the PLC "warning of electrical
component life warning" turns ON.
The warning level in the table is the initial value and so it is possible to change from 7 segment monitor.
If warning level is set to 0, warning judgment is not performed.
Driver's electrolytic capacitor lifetime warning
Warning content Lifetime warning of electrolytic capacitor mounted on GSK drive
Warning level 4 years (lifespan: 5 years)
Determination
method
We write the date of manufacture when manufacturing the GSK driver.
The GSK I / F compares the manufacture date of each driver with the current date and
It judges whether it exceeds the warning level or not.
※
However, if the date of manufacture is all 0, it will not be checked.
Warning Reset That is impossible.
Driver's relay lifetime warning
Warning content Lifetime warning of the drive power-on relay mounted on the GSK drive
Warning level 80 thousand times (lifespan 100 thousand times)
Determination
method
It clears the relay operation count to 0 when manufacturing the GSK driver.
The GSK controller increments this count by 1 each time the relay is moved.
The GSK I / F checks the number of relay operations of each driver and it judges
whether it exceeds the warning level or not.
Warning Reset That is impossible.
Driver's EEPROM lifetime warning
Warning content Lifetime warning of EEPROM rewriting installed in the GSK drive
Warning level 800 thousand times (lifespan 1 million times)
Determination
method
It clears the EEPROM write count to 0 when manufacturing the GSK driver.
The GSK driver increments this number by 1 each time EEPROM rewrite is performed.
GSKIF checks the EEPROM write count of each driver and it judges whether
it exceeds the warning level or not.
Warning Reset That is impossible.
③
Nut runner failure prediction warning
When the following warning condition occurs, the output signal "protection warning" turns ON.
The warning level in the table is the initial value and can be changed by the personal computer.
When the warning level is 0, warning judgment is not performed.
Driver overload warning
Warning content The load current of the GSK driver exceeds a certain value.
Judgment target Overload alarm level (percentage of alarm level)
Warning level 80%
Determination
method The GSK driver notifies the GSK I/F of the overload alarm level of the motor.
GSK I/F checks whether the judgment value has exceeded the warning level and
exceeded.
Warning Reset Warnings can be reset by computer operation.
It resets when turning off the power of GSK I/F.
