Can anybody tell me how do I disable one of (2) double drives(BLII-D) on a Okuma lr-15 with a 5020L control ?

Machine lock and e-stop disable...I think on the lathe the only other way is to unplug it, but then you will get an alarm. What do you hope to accomplish?

We have an ALARM has shown: 201-8 SERVO AM MA-AXIS 2C6.

The servo amplifiers for both M-axis are damaged.

Since we do not use those two axis I would ask you to help me how, if it is possible, we can disable/remove these two M-axis from the configuration of the machine, or make some bridges on the connectors of the servo amplifiers, so that the alarm would not appear at all and we will be able to use the machine without those axis?

To enable an Okuma 5000 or 5020 with a BL-D or BDU drive removed, jump pins 13,14 & 10 on CN1 (connector that goes to the circuit board) together to mask any alarm. Then jump 19 & 20 on CN10 (goes to the drive base) connector together to enable the bulk Power supply. MAKE SURE YOU GOT THE RIGHT PINS, OR YOU WILL DAMAGE YOUR MACHINE. Great way to use a machine with just the upper turret or without an A axis.

To enable an Okuma 5020 with BL2-D drive removed, jump pins 8 to 10 on the XB1 connector(s). For a dual drive you have to jump both connectors. We do this all the time so we can test one BL2-D5050A dual axis drive on our 4 axis Okuma 5020 control. We rebuild & exchange almost all Okuma servo drives.

Hello Doctorcnc, i am trying to disable an axis as you dicribed, but on the CN10 there are only 5 wires going to that connector, and they are on 1,2,3, 6,7. If i connect 19 and 20, there are no wires.

Hi Kotronik, did you have success with the procedure as by doctorcnc? Please let me know, i have same problem, and my problem is that CN10 is wired only on 1,2,3,6,7. and not on 19&20
