21 system error MAZATROL 640M
Anybody familiar with this fault??
What is the exact alarm you are getting? Is it a windows alarm or are you getting this on the alarm diagnosis screen?
Did you replace the battery in the NC or the MR-J2? What do you mean you cleared the MR-J2? Did you reload the parameters to the MR-J2?
21 system error is always in the screen, But when I was looking around i went to the MR-J2 and as soon I get in, a message came up "PC-NC_I/F_ERROR" then down this, "[IMG]![/IMG] The read error occurred between the NC and the personal-computer. 0001" I close this message and another came up,Originally Posted by onthebumper
"Communication error between personal computer and the servo amplifier, Check Connection."
Then I closed this one and another window came up,
"SPECIFICATION CHECK FOR CONNECTED MR-J2-CT"
It can not distinguish between the Rotary Axis and the Linear Axis, For communication error. Wich do you want to connect the Rotary Axis or the Linear Axis?.
Error 21 is a software alarm and it may be because one or more of your MR-J2s lost its mind. I'd reload the MR-J2 parameters like onthebumper mentioned.
What machine is this? and how did this all originally start?
It's just a part..... cutter still goes round and round....
Also check the MR-J2 drives. They should be flashing some alarm on them. If they are blank or have a solid display when the NC control is on then one of the drives is bad or you have a communication problem to the drives.
21 SYSTEM ERROR
The problem was in one of the MR-J2 drives, Someone changed a switch that is on the front of the drive, The LED screen in the front of the drive has to digitals numbers and on the right side has a switch with numbers (0 to 10) and letters (A to F), I have four drives and none of the drives can't have the same number, so two drives were using the same number(2), I have to go to the MR-J2 and check the axis settings and give them the right number. I WANT TO GIVE THANKS TO EVERY PERSON THAT TRY TO HELP ME,THANKS ALOT

Re: Mazak 640M System Error 21
Guys, I'm having the same issues on the Mazak integrex 300 640..Where exactly is the MJ-J2 driver located? Please help!!
Re: 21 SYSTEM ERROR
Hi guys, I found out one of the MRJ drives is bad, showing solid number 88. What is it mean? and how do I fix it? Do the batteries need to replace? @ MR-J2-200CT
Any input would help, please.....
Re: 21 SYSTEM ERROR
This is related to memory error. Try initializing the drive unit. If it doesn't work then the drive control card needs to be repaired
