Solution
1. Ground Joystick Release input.
2. Check wiring for opens, shorts, and mis-wired connections.
1. Make sure the cable is securely connected at both ends.
1. Check PC-AT power and check proper card installation in bus slot.
2. Download operating system.
1.a. Recycle power to the AT6n00.
1.b. Ensure +5V is not shorted to GND on the I/O connections.
1. Download operating system.
1. Computer must be on since the AUX board turns on and off
automatically with the computer.
2. Make sure both ends of cable connectors are securely latched.
3. Check AC power to AUX board.
1. See LED troubleshooting as noted above.
2a. Move load off of limits or disable limits with the LHØ,Ø,Ø,Ø
command.
2b. Set LSPOS to a value greater than LSNEG.
3. Set pulse width to drive specifications using the PULSE command.
4. Set drive fault level using the DRFLVL command.
5. Check step , direction, drive fault, & limit connections.
6. Ground P-CUT connection on AUX board.
7. Remove power and clear jam.
8. See problem: Torque, loss of .
1a. Switch encoder connections A+ & A- with B+ & B-.
1b. Switch DIR+ with DIR- connection to drive.
2. Check encoder wiring.
1. See Interrupt Selection section below.
2. See Address Selection section below.
1. See Address Selection section below.
2. See Downloading Errors table below.
1a. When inputs will be pulled down to 0V by an external device, connect
IN-P to +5V supplied or other positive supply.
1b. When inputs will be pulled to 5V or higher by an external device,
connect IN-P to 0V.
2. Connect external power supply's ground to AT6n00's ground (GND).
3. Check wiring for opens, shorts, and mis-wired connections.
1. Outputs are open-collector and can only sink current -- change wiring.
2. Connect OUT-P to the +5V supply on the AUX board or to an external
supply of up to 24V.
3. Connect the external power supply's ground to the AT6n00's ground
(GND).
4. Check wiring for opens, shorts, and mis-wired connections.
1. Check wiring to the drive, as well as other system wiring.
2. Check power to drive.
3. Check drive status.
4. Check drive status.
5. Enable drive with the DRIVE1111 command.
1. Connect external power supply's ground to AT6n00's ground (GND).
2.a. Check wiring for opens, shorts, and mis-wired connections.
2.b. When inputs will be pulled down to 0V by an external device, connect
AUX-P to +5V supplied or other positive supply.
2.c. When inputs will be pulled to 5V or higher by an external device,
connect AUX-P to 0V.
