hello dears,
Does anyone have any information on these cables xp1 to xp8 pinout resolvers ( kuka kr210 - kr c2)?
thanks

Resolver cables use:
1,2 = stator1 (SIN)
11,12 = stator2 (COS)
10,7 = rotor (excitation)
8,9 = RTD (about 600 Ohm at room temperature, about 1k when boiling hot)
3,4,5,6 = shields of those four pairs
more about it is in answer to your other post
where is gnd +24v panic? t
i want to compare aro servo motor (servo gun) and 7th axis kuka servo motor.
aro servo motor x52 pinout with 19pin an 7pin (n.c.)
i want to connect this servo to rdc box
Connector pinout shows all signal of the gun. You can't connect some signal to RDW box. For example digital I/O's and 24V signal should be connect externally or to Robot I/O modules.
In RDW you can just connect resolvers signal and temperature sensor.
resolvers do not use DC, they are pure AC devices and have no onboard electronics (all electronics is far from motor in the RDC). think of a transformer. primary is excited by AC sine. two secondaries produce the same frequency AC but different amplitude which depends on sensor angle. if one knows SIN and COS amplitudes, one can compute the shaft position (angle).
RDC produces AC to excite the primaries and samples SIN/COS values of the secondaries. measurements are taken at the moment excitation wave is one of the peaks. all of this is controlled by DSP on RDC.
encoders work differently, they are digital devices evaluating on/off state of optical beams. there is no single encoder type. there are many variants and they are not compatible. connecting feedback sensor to a controller is not as simple as connecting push button to a digital input of some controller. this is why normally one uses motor and servo drive as a pack (matching pair).
but that is only one of the interfaces... the other is between servo drive and motion controller. and here are also numerous options which are also incompatible. so how exactly do you plan to have KRC tell the Panasonic drive how much to move?
