Troubleshooting

Problem 
 
 
 Resolution 
 
 
 
 Red and green status indicators off 
 Check that the power supply to SMD4 is correctly connected and meets the requirements given in section Technical Information 
 
 
 Red status indicator flashing or lit solidly 
 Each indication corresponds to a fault, review section Faults 
 
 
 Motor does not move when commanded 
 
 Is a fault present? Check the red status indicator on the front panel, and use the SMD3 software or remote interface to determine the nature of the fault. After the fault has been fixed, run the CLR command, or use the reset fault input to restore normal operation 
 Check the motor wiring to the SMD3; disconnect the motor, and use a multimeter to measure the resistance of each phase, see section Lead Identification , which should be approximately 3 – 15 ohms 
 
 
 
 Joystick does not work 
 
 Is joystick mode selected? 
   
 If you want to switch to joystick mode automatically on connection of the joystick, see setting AUTOJS and section Joystick . The joystick must be wired correctly for the auto-detect function to work as described in section Joystick .
