POWER CONNECTOR AND INDICATOR LED's

Power Connector

The SD17040C operates on 115Vac. If 230Vac is the only power available, consider using one

GND

of the 230Vac drivers available from AMCI. Information on these drivers can be found on our

website, http://www.amci.com. If this is not an option, a step-down transformer must be

installed to power the SD17040C. The transformer must have a minimum power rating of 600

VA.

AC POWER

The SD17040C must be grounded for proper operation. Grounding is accomplished with the

95 – 132 V

GND pin on the power connector, and through proper bonding to the enclosure. Power con-

50/60 Hz

nections should be tight. Loose connections may lead to arcing which will heat the connector.

Phoenix Contact specifies a tightening torque of 4.4 to 5.4 lb-in (0.5 to 0.6 nM)

Indicator LED's

The SD17040C has two indicator LED's.

STEP/FAULT

! Green:

Driver Operational

! Flashing Green:

Driver Fault (The Over Temperature and Over Current faults can be cleared with the Disable Input.)

! Red:

1) Over Temperature Fault: The heatsink temperature exceeds 90°C (195°F)

2) Over Current Fault: Generally, a short exists somewhere in the system. This can be a short in the

motor or in the driver itself.

A) Phase–Phase Short: There is an electrical short between the two motor windings. The short

B) Phase–Ground Short: One of the motor's windings is shorted to earth ground. (The EARTH

C) Back EMF: In applications with large motors and high deceleration rates, back-EMF generated

3) Interlock Fault: The two Interlock Terminals on the motor connector are not connected with a short

jumper.

! Flashing Red:

! Flashing Red/Green @ 1Hz:

driver was ready for them. The driver was disabled, in a fault condition, or had not completed its initialization

sequence on power up or reset. The stepper motor position will be invalid. The motor is not disabled and can still

be driven. While there is motion, the LED will flash at approximately 4 Hz.

! CURRENT LOOP GAIN:

5 all turned off) When set to AutoID, the driver will determine the parameters of the attached motor and

will flash the Step/Fault LED green the number of times that the parameter should be set to. Flashing

red indicates a problem with the motor wiring or the motor current is set to zero. Further information

can be found in the next section of the manual, Verifying System Setup.

Power is applied to the driver in the range of 95 or 132 Vac.
