Galil 4143 motor not moving
« on: November 09, 2018, 10:13:58 AM »
 ’m having some problems when trying to control a PI M-062.PD by using a DCM-4143-BOX6D3640. I have checked all my connections and they all are correct. I’m using the same controller configuration I had successfully used in another application (with same component PI M-062.PD). So, considering that connections are good and controller configuration is been proven, I’m having some troubles to determine where the problem is coming from. I can read the encoder’s information (tested by moving the motor by hand), but the motor does not move when sending the BG command.  I’m getting a position error and also a hall error (hall input =7) despite de fact my configuration specifies to ignore the hall sensor states (BRA 1).  Finally The servo motor has its own independent (external) power supply.

 will appreciate any information or advice you could provide

Hello. Are you using Galil Tools or Galil Suite? Make sure you have the MT command set correctly for motor type. Since you have encoder feedback and can get a position error, check TT and it should read just under 10 indicating the controller is giving analog output command but motor is not responding. Give a MO(x,y,z or whatever axis you have it connected to) then another tt command and the value should drop to zero. moving the motor shaft should still give encoder pulses. Next give the SH (shx, shy, etc). That tells the controller to Servo Here that axis. Servo Here (SHX) means to allow the servo motor t be commanded based on encoder pulses and command signal.
Example as follows:
MT - tells what type of motor is configured
TT - means Tell Torque. This reads the command voltage given to the amp for each axis.
MO - turns the motor off for each axis. (MOX, MOY, MOZ)
Remember to usa all caps.
if I can more help, let me know. Regards, Allen
