3-30 Description of diagnostic letters F… and E…

E255 Feedrate-override S-0-0108 = 0

If absolute positions are selected while in a positioning operation mode,

the control drive must be homed to a reference position. If this is not the

case, an absolute position cannot be reached. The drive rejects this

positioning command and stops. The warning E254 will be given.

Cause:

Absolute positioning was selected without the drive being referenced.

Remedies:

1.

Do the homing (referencing) command with the drive or

2.

do only relative positioning.

See also the function description «Drive-Controlled Homing».

With the parameter S-0-0108, Feedrate override, the travel velocity of

all drive-controlled travel commands can be changed proportionally

(in %).

If the value of this parameter is 0, the travel velocity is also 0. With

velocity = 0, the motor remains stationary despite having a commanded

value.

Causes:

1. The parameter S-0-0108, Feedrate override is 0.

2. For devices with analog inputs: Feedrate override via analog input is

activated, and the voltage at the analog input is 0.

3. The feed potentiometer of the connected control system is at 0 or is

being evaluated incorrectly.

Remedies:

For 1.: Set Feedrate override > 0, so that the drive moves. Full speed is

attained with 100% .

For 2.: Apply a voltage > 0 proportional to the desired speed,

+10V corresponds to 100 % (full) speed.

Alternative: De-activate Feedrate override.

For 3.: Turn the feed potentiometer cautiously, check the analog signal

and the evaluation for it.

Homing».

Добрый день

на Siemens MCP (панелях управления станками) (например на серии 808D A) очень удобные

Переключатели Feedrate override (Коррекция скорости подачи) (фото прикреплено) (по-моему они на 16 положений каждое на 15 градусов)

на другой проект (не станок) хотелось бы использовать аналогичные переключатели… от Siemens или другого производителя .

подскажите заказные номера….аналогичного оборудования (Siemens или любой другой, интересует именно такой переключатель не маховик-энкодер, как правильно называется этот переключатель ?)

сколько у него дискретных выходов?

   Fanuc 15M — Feedrate Override Knob Disabled?
   

   I have a Niigata HN80C with a Fanuc 15M controller. It appears the feedrate override switch is disabled in the controller. The controller is seeing the switch change and the binary numbers are changing in the controller but the feed rate is not changing during a program. Does anybody know how the feedrate override can be disabled and more importantly how it can be turned back on? Thanks.

   There is an M code for this on some machines to stop operators messing with feedrate and spindle overrides in program, Rapid traverse cannot be locked out. Check the M code listing and also for operator settings or keep relay options.

   Does this happen in all programs or just some of them? I don’t have any documents here at home but there is a #3000 variable that will disable the feed override. This is a shot in the dark but IIRC it may be #3010 set to 1 will disable the over ride and set to 0 will allow the override. I used this on a product line that I set up so the operators could not override during the cut. Then I enabled it right after the cut so anything else done on the machine you can override. I can check tomorrow and get back to you when I get time. If you can’t wait I know that I have posted this variable once before in a thread god only knows when but a search for #3000 with my name may find the thread for you.

   It is #3004 on 0i, possibly different on your control.
   But, this variable starts with 0 in a new machining session, enabling feed override. Possibly, it is being disabled by your program.
   See the attachment for more details.

   Sinha,
   You are correct. It is the same on the 15series as it is the Oi series. I just double checked this morning.

   Ktmrider,
   Check to see if this is being used anywere in your programs. Especially in any macros that might be running. I also think that once this is active it stays active so you may want to try setting #3004=0 in MDI mode. If it is set to 2 then it will disable the override.

   feedrate override
   

   there is an M code that is used on some controls to disable the feed-rate override…i think it is M49 to disable it and M48 to cancel.
