EL7041 with stepper NEMA17

HI everybody
I'm using an EL7041 driver to control a nema17 stepper motor, the problem is that the stepper has a strong overheating during its operation and I can't understand what the problem is. does any of you have any ideas?

I don't know anything about those drives, but did you set the max current? Do the drive have a step down or at rest current setting that you need to set?

Hello Noal

To control the current output of your motor terminals you can use
EtherCAT commands. These commands are entered at the
command line in a terminal window.

With the EtherCAT master running you can list the position of each
terminal on the bus using the command:

ethercat slaves

This command will list the position of each terminal on your bus.
Use this position in the commands below to address each terminal

which you wish to adjust by replacing the $ in each command with

the terminal’s position in the bus.

Read Maximum Motor Current (mA)

ethercat upload -p $ -t uint16 0x8010 0x01


Set Maximum Motor Current to 100 mA

sudo ethercat download -p $ -t uint16 0x8010 0x01 100


These parameters are detailed on page 196 of the PDF
documentation for the EL7041.

You can set the current to any value between 0 and 5000 mA.

By the way, what is the current rating of your motors?

Allan

the current rating is 1,8A and i have already set it but the motor in this situation has few torque,the only way to increase the stepper torque is increase the current too, but in this way the heat increase. why?
is it possible that the drive is not suitable for this motor?
thank you

NEMA 17 is a bipolar motor for this has 4 wire,the wiring is correct.
his torque is anyway too low for this motor .
in my opinion this problem it's due to the some wrong parameters set in the drive el7041
thank you

If you suspect a setting in your motor drive terminal you could reset it back to factory settings.
Perhaps you need larger motors to generate the torque you need?

when i set the current max at 1,8A the stepper it is not hot but the torque is very low, if i try to increase the current the torque increase too, but also the temperature of stepper. The stepper with 1,8A shuold be have more torque (I'm sure of this)
