I have an application wich require to contorl a stepper motor via serial communication (RS485), I've bough a IDX 7505 for this porpose, and now I have some questions:
#1. About the acceleration parameter, I see in the manual a range from 0 to 250000, could you pls explain what does it means exactely? I mean what are the units? pulses/second? I would like to know the magnitude.
#2. My hardware is already connected and also connected to a hyperterminal, and the motor works fine, I mean the driver execute the orders received via RS485 from the hyperterminal, I'm using a QSH-5718-55-30-098 stepper, I'm reading in the manual of the motor and in the driver IDX 7505 as well that the maximum speed for a motor like that is 20 turns/sec who is equal to 4000pps from the driver, but as soon I'm near 10 turns/sec, the motor start to make strabge movements or jumps and begins to lose steps until stops. I'm working in a normal default mode for chopper and NO stallGuard, could you pls. explain what is happening and it's solution?
#3.The main porpose for my application, as I said, is to control the position of one axis, so I can't find information how I can set a value of position, for example 435steps that is equal to a 43.5mm in my mechanical application, The idea is to do so just sending the right orders via RS485 and the motor must run until reach those 43.5mm. Can I do this? how? I've trie with the commands P and R but the P command seems like is to set the internal counter of steps of the driver to a desired value, and the command R is just returning via RS485 the actual position or step counter, but what I need is to tell the driver how many steps have to move and then stop until next order of movement.
Pls try to answer and support me as soon as possible, I'm not an student and this is a professional or industrial application that I'm developing.
