VERIFYING SYSTEM SETUP

System Checkout

1) Verify all wiring and grounding before applying power to the SD17040C.  Make sure the rubber boots are 

on the driver’s motor and power connectors.

2) Apply 115Vac power.  With the motor attached, the power and status LED’s should come on green.  A 

problem exists if either LED does not light, or the Status LED is red.  Remove power and refer to the 
Troubleshooting section of this manual which begins on the following page. 

3) Check for holding torque on the motor.  If you have less then you expected, the most common causes are 

improper motor current switch settings or having the Idle Current Reduction turned on. 

4) The Self-Test feature of the SD17040C allows you to verify your motor wiring without an indexer.  With 

power applied to the driver, toggle the SB4-1 switch.  The motor will begin to rotate clockwise at 60 RPM.  
You must remove power from the driver to stop the rotation.  If the motor rotates in the counter-clockwise 
direction, swap the +B and –B connections.  If the motor does not rotate at all, verify your current setting 
and the motor’s wiring.

5) Have your indexer make a slow move in the clockwise direction for one turn.  While the turn is in progress, 

the STEP LED should blink.  Verify that the motor rotated in the correct direction for one complete turn.  If 
you are using an optical encoder or other position feedback, verify that the indexer or controller is reading it 
properly.  

6) Repeat step 5 with a one turn move in the counter-clockwise direction.  Again verify that the motor rotated 

in the correct direction for one turn.

Any failures at steps 5 or 6 are usually caused by not setting the Pulse Train Input switch cor-
rectly or programming the wrong number of pulses in the indexer profile.  If the motor rotates 
in the wrong direction you can swap the +B and –B connections instead of altering your pro-
gramming.

7) If you are using the Disable Input, verify its operation with the motor stopped.  Note that the motor will have 

no holding torque while this input is active and the motor’s shaft will be free to rotate.  

8) If you are using the Fault Output, verify that it is On (conducting).  Remove power from the SD17040C, 

disconnect the motor, and re-apply power.  The STEP/FAULT LED should be red and the Fault Output 
should be off (not conducting).

9) Remove power and re-attach the motor.  Power the driver.

10) Consider altering the motor current or enabling the Idle Current Reduction if it is not already enabled.  

Lowering the motor current or enabling Idle Current Reduction can greatly reduce motor heating.
