G320X SERVO DRIVE REV 10: May 13, 2010 Thank you for purchasing the G320X drive. The G320X DC servo drive is warranted to be free of manufacturing defects for 1 year from the date of purchase. Any customer who is dissatisfied with it or is unable to make it work will be cheerfully refunded the purchase price if the G320X is returned within 15 days of the purchase date. PLEASE READ FIRST BEFORE USING THE G320X: If you are not familiar with DC servo drives please do the following setup instructions with the motor on the bench before mounting it on the mechanism it will eventually run. This will allow you to get a baseline motor behavior of what to expect. Before you start, you must have a suitable encoder mounted and properly aligned on the motor. Follow the manufacturers instructions on mounting and aligning the encoder if the motor doesnt already come with one. Next you must have a DC power supply suitable for the motor. The power supply current rating must equal the maximum current you expect to run the motor at. Finally, have a STEP and DIRECTION pulse source available. Before going on, turn the P, I, D, and LIMIT trimpots to the 11 oclock position. The trimpots are single-turn so be careful not to over-torque them. G320X PINOUT TERMINAL 1 Power Ground Connect the negative (black) lead of your power supply to this terminal. TERMINAL 2 Power (+) Connect the positive (red) lead of your power supply to this terminal. It must be between +18VDC to +80VDC. TERMINAL 3 Armature (-) Connect the black lead of your motor to this terminal. TERMINAL 4 Armature (+) Connect the red lead of your motor to this terminal. TERMINAL 5 ERR/RES This is the ERROR and RESET pin. For a full explanation read the section titled ERROR/RESET PIN on page 6. TERMINAL 6 Encoder Ground Connect the encoder power supply ground to this terminal. TERMINAL 7 Encoder +5VDC Connect the encoder +5VDC pin to this terminal. TERMINAL 8 Channel A Connect the Channel A pin of your encoder to this terminal. TERMINAL 9 Channel B Connect the Channel B pin of your encoder to this terminal. TERMINAL 10 Direction Connect the DIRECTION signal to this terminal. TERMINAL 11 Step Connect the STEP signal to this terminal. TERMINAL 12 S/D Common Connect this terminal to either +5VDC or signal ground. 1 G320X SERVO DRIVE REV 10: May 13, 2010 DIP SWITCH SETTINGS The G320X has a 10 position DIP switch that is accessible when the cover is removed. These switch settings control many of the features of the G320X and are labeled SW1 through SW10. REMOVING THE COVER: 1.) Remove the two 2-56 Phillips-head screws on the bottom of the drive. 2.) Slide the cover backwards while still lifting until it clears the drive. REPLACING THE COVER: 1.) Slide the cover forward over the drive until the holes in the cover line up with the holes in the bottom plate. 2.) Replace the screws on the bottom of the drive. EXPLANATION OF SWITCH FUNCTIONS SW1 Not used SW2, SW3 MUL1 and MUL0 respectively Sets the G320X pulse multiplier SW2 ON and SW3 ON = Step pulse times 1 (default) SW2 ON and SW3 OFF = Step pulse times 2 SW2 OFF and SW3 ON = Step pulse times 5 SW2 OFF and SW3 OFF = Step pulse times 10 SW4, SW5 SR1 and SR0 respectively Sets the G320X following error limit SW4 ON and SW5 ON = +/- 256 count following error limit (default) SW4 OFF and SW5 ON = +/- 512 count following error limit SW4 ON and SW5 OFF = +/- 1024 count following error limit SW4 OFF and SW5 OFF = +/- 2048 count following error limit SW6 HEDS SW6 OFF = Default SW6 ON = Turned on if using encoders with HEDS optical heads or open collector encoders. Disables encoder failure detection allowing user to run encoders that dont have line drivers or active pullup. SW7 TORQ SW7 OFF = Use LIMIT trimpot setting only (default) SW7 ON = Allow 20A for 1 second, then use LIMIT trimpot setting SW8, SW9, SW10 GAIN2, GAIN1, and GAIN0 respectively Current mode servo gain SW8 ON, SW9 ON, SW10 ON = Lowest gain SW8 ON, SW9 OFF, SW10 ON = Low gain SW8 ON, SW9 ON, SW10 OFF = Medium-low gain SW8 ON, SW9 OFF, SW10 OFF = Medium gain 1 (default) SW8 OFF, SW9 ON, SW10 ON = Medium gain 2 SW8 OFF, SW9 OFF, SW10 ON = Medium-high gain SW8 OFF, SW9 ON, SW10 OFF = High gain SW8 OFF, SW9 OFF, SW10 OFF = Highest gain G320X TERMINAL WIRING: IMPORTANT: When first testing the G320X, connect ERR/RES (Terminal 5) to ENC+ (Terminal 7). IMPORTANT: Do not connect the motor to the G320X until STEP 6. IMPORTANT: Please follow the next steps in the sequence they are given. 2
