Hello.
I want to make a vacuum griper with suction cups working with venturi effect.
They will grip steel sheet 1mm (non porous) payload about 10-20kg.
I don't know how many liters/min air flow i must have to size air compressor and tank.
What suction cups must get and how many also what vacuum generators and how many of these must get
Can you give me a starting point ?
Thank you.
I have read here in some post that someone configured resolvers with rdw tool.
How can do this?
Or is there any change to use saferdw2 with simple esc-ci
without safeoperation tech package with some jumpers in saferdw2 pcb?
I have replaced rdc1 with rdc2 and switched ksd48s between A2 and A3 and the following errors are the same they are due to hard limit so it is ok.
1133 Gear torque exceeded axis A2
1161 Ackn. monitoring of the actual velocity A2
The following errors are gone with rdc2
1241 Ackn I-t mon. current limit of motor cable A2 after 60.0 s exceeded....
1242 Ackn I-t mon. current limit of motor cable A2 after 60.0 s exceeded....
So the problem is rdc1.
When put rdc1 first thing to do is log on as Administrator in kss and set correct mada from hdd.
So mada are correct.
I have got some screenshots with rdc2 the offsets in rdc tool.
Can put these offsets to rdc1?
I want to use rdc1 because i don't have free spare rdc2 only rdc1 and saferdc2 witch works only with
tech esc-ci3 and safeoperation tech package
Robot gives me in T1 these alarms
The following errors for A2 axis are thrown when jog the A2 back in a specific angle(very back near counterbalance) not in other angles maybe is the hard limit of robot so this is normal error.
Can this be a cut power cable that in this angle looses contact ?
1133 Gear torque exceeded axis A2
1161 Ackn. monitoring of the actual velocity A2.
Also these random errors for example when jog A3 or A6 axis after press for 60sec the dead mans button in kcp.
1241 Ackn I-t mon. current limit of motor cable A2 after 60.0 s exceeded....
1242 Ackn I-t mon. current limit of motor cable A2 after 60.0 s exceeded....
Can all these errors be because rdw1 is not configured correctly for krc2 ed05 robot ?
How can i configure correct rdw1 ?
I have used esc-ci instead esc-ci3 to krc2ed05
with some jumpers and works.
What are the differences between esc-ci extended (that has all components populated to pcb) vs standard(no esc node)?
Ok tested krc2ed05 robot with rdw1 and kss 5.6.12
and works.
It will work with saferdw2 and standard esc-ci (not tech esc-ci) or saferdw2 must replaced with rdw2 to work with standard esc-ci?
I have very serious noise problem with ebm-papst 24v krc2ed05 pc fan (the fan that cools pc inside cabinet)
This fan gets about 27V and has tacho output to mfc3 if disconect it due to tacho
kss reports error...
The fan has no problem(for example bad bearings) but due to lot of rpm make crazy noise
more than the big cabinet fans.
What can i do for this probem ?
I have a kr240 ed05 robot that is saferobot with saferdw2 .
Can i use this robot some with a simple krc2ed05 (without saferobot pcbs)
or must change saferdw2 with rdw2 to use it with simple krc2ed05 cabinet ?
Update:
I have used an krc2 ed05 robot with rdw1 instead rdw2 -> works
with saferdw does not work.
And krc2 ed05 cabinet with esc-ci(some rewiring needed) instead esc-ci3 -> works.
Hello.
Is there a pinout diagram for RDW2 X9 pcb connector to X31 socket (data cable) ?
Also how can install an RDW2 ? Which bolts must be plastic for insulation ?
Hello again.
Has anyone something newer about type of X20-X30 connectors for krc2 power cable ?
press has a foot pedal that when you press it the ram goes down and terminates at the maximum pressure you have pre-set.I can pre-set pressure in larger value so to not stop by pressure limit.
If put a linear scale in the side of ram can pid positioning closed loop
reading the glass scale and driving the foot pedal command to setpoint distance.
robot controller must read the distance from scale or from mcu that reads the scale
and follow the path.
I have found somewhere the kinematic mathematic types of sheet rotation due to ram movement.
Because of press brake is a simple old school machine with only manual pressure adjustment i plan to put a linear glass scale on the side of ram to measure the distance of moving the ram(this scale outputs quadrature signals).
I want to control the press ram from robot via pid positioning loop if this can be done inside the krc2
if not i will do the pid positioning loop in an mcu(i can program an mcu for this) and mcu will have an input of how many mm must move and get that command from krc2.
I have some experience of PID control loops.
Can i read a linear scale ( incremental quadrature signals ) from krc2 and do the pid loop of press brake's ram movement in robot controller or need external plc-controller to read the scale and control the robot?
Hello.
Because bendtech technology package is not available anymore for krc2
if i have a simple hydraulic press can install a linear scale to ram and feedback
its output to robot wago devicenet inputs ?
How can modify motion of robot real time with the input from linear scale ? RSIXML ?
If feedback linear scale output to other-external plc-controller how can control the robot
motion in realtime from this plc-controller ?
without cable x21.1 to x41 and esc-ci3 with x23
can work?
I got RDW1 in very good price already...
Anyway if doesn't work i will have it as spare for other robot.
I have a working kr125/3 with RDC1
and krc2/kss 5.6.12 cabinet.
Can backup rdc flash memory before fails
so after failure to solder a new same type flash chip and write the stored backup?
Also if replace rdc of a krc2ed05 robot
with rdc from a krc2 robot will work?
I know that installing to krc1 robot krc2 rdc works because it is upgrade but the opposite works(put krc2 robot rdc to krc2ed05 robot)?
I will use this rdw board instead of saferdc
This will work with krc2(not ed05) mfc2/dse-ibs c33/ kss 5.612 ?
To clarify i have krc2 (not ed05) with soy motherboard with MFC2 & DSE-IBS C33 with winxp sp2 / kss 5.6.12 (hardware is not ed05 but software is ed05) and esc-ci standard version not esc-ci3 tech.
If i get an rdw2 pcb from other krc2 robot and put it instead of saferdc will work ?
Thank you.
