APPENDIX C
TROUBLESHOOTING
Self Test Mode
The Self Test can be used to familiarize yourself with the drive or test the SD17063 and motor hookup with-
out an indexer. To run the Self Test on a bench, use the following instructions:
1) Indexer connections are not necessary. If you have a 5 to 24 Vdc power supply, you can wire
switches to the ±Disable and ±Reset inputs. See figure 5.4, Single Ended Input Connections, on
page 35. If your supply is greater than 5 Vdc, you must uses the current limiting resistors given in the
figure.
2) Referring to the SD17063 Worksheet on page 17, set the motor current to an appropriate value for
your motor. SM23’s can have their current set to 1.0 amp, SM34’s to 2.0 amps, and SM42’s to 3.0
amps. If you have already determined the current setting for your application, you can use that value.
3) Still using the worksheet, set the Output Waveform switches to -4%, (SB2-4 = 0, SB2-5 = 1). Set the
Resolution switches to 200 Steps per Turn, (SB3-1/2/3/4 = 0). Set the Anti-Resonance switch to
Disabled.
4) Slide the rubber boot onto your motor’s wires and wire the motor to the Motor Connector. If you’ve
already determined how the motor will be wired, then connect it that way. If you haven’t determined
how the motor will be wired, then wire four and eight lead motors in parallel and use the Center Tap
connection for six lead motors. Cover the connector with the rubber boot and insert the connector
into the drive.
5) Slide the rubber boot over your power cord, and wire it to the connector. Slide the boot onto the
connector and insert it into the drive. If bench testing, you will have to supply your own power cord.
Verify all connections before applying power.
You must use a 3-prong grounded outlet when applying power to the SD17063. The
drive may pose a serious shock hazard if not properly grounded.
h
When you apply power to the drive the motor should start turning counter-clockwise, (looking at the
shaft), at a speed of 1 RPM. If the motor rotates clockwise, remove power from the drive and reverse
the ±B motor connections. At this point the
POWER LED should be on and the STEP
LED should be
blinking.
h
If you have wired the ±Disable input, apply power to it. The motor will stop rotating, and it will have
no holding torque, while the input is active. The
STEP
LED will also turn off. When power is removed
from the input, the motor will start turning and the
STEP
LED will blink again.
h
If you have wired the ±Reset input, apply power to it. The motor will stop turning and will have no
holding torque. The
STEP
LED will also turn off. While power is applied to the ±Reset input, change
the Output Waveform switches to select Pure Sine. (SB2-4 and SB2-5 = 0.) When power is removed
from the ±Reset input, the motor will not turn because the SD17063 is no longer in Self Test mode.
If the drive and motor do not work as expected, then a problem exists with your setup, the motor, or the drive.
Refer to the troubleshooting tables on the following page for information on problems and possible causes. If
you cannot resolve the problem with the troubleshooting tables, call AMCI technical support for assistance.
