JAVI Posted July 6, 2006 Report Posted July 6, 2006 Hola to all. I need to know if it is possible to handle a servoamplifier MR-J2S-60A for pulses of exit of the encoder of another servoamplifier MR-J2S-60A. If this it is possible to do it is possible to change externally this reference with a trim for example? The pulses of the exit of the encoder of the servoamplificador are to that voltage. Thank you for the help. Quote
panic mode Posted July 7, 2006 Report Posted July 7, 2006 Hi Javier, i didn't use A in a while, but i think you are right that they use pulse trains (B version of drives connects to SSCNET network). if you send pulses from one drive to another, the later one will follow the first one. changing parameters in the drive it is possible to change speed ratio (i think this is what you are after). is this something you need to change or adjust on fly? i think only way to do that without motion controller or similar is by changing ratio in slave drive (plc to send information serialy to slave drive). what exactly you want to achive? --- edit --- just checked the manual and this drive has analog inputs and outputs that could be used for tying drives together. particular just check section 3 of user manual (SH_NA_030006). use of analog I/O depends on parameter settings (assignment of I/O and selected mode of operation, eg. speed, torque etc.) Quote
FNMdeJong Posted July 7, 2006 Report Posted July 7, 2006 (edited) The Amplifier A type is pulse driven. To connect two drives together where one drive functionates as a master and the other one as a slave just connect the encoder output pulses from the master to the input pulses of the slave. In this case you control the master drive and the slave will follow. Set the parameter number 27 encoder output pulses to the disired resolution. This in combination with parameter 3 and 4 and you can create a full scale of the speed range. Wire the slave encoder output pulses on connection CN1A to the master input pulses on connection CN1A. Do not use the analogue output to control the slave, you will loose precision. Edited July 7, 2006 by FNMdeJong Quote
JAVI Posted July 7, 2006 Author Report Posted July 7, 2006 Thank you for the answers. I have now several questions: 1. Which is the voltage of the pulses of exit of the encoder of the servoamplificador?, in the manual SH (NA) 030006-B does not say. 2. Is it possible to fit across a PLC the reference of entry of the servoamplificador slave?. 3. Could use I a relay of solid state to 24V dc for to drive the exit of encoder?. Thank you.
