For SD17060B-24 Drives…
As of January 2009, the SD17060B-24 has been phased out of production and replaced by the standard
SD17060B. The older SD17060B drivers required an external resistor when using a 24Vdc input signal and
the SD17060B-24 drivers had this resistor added internally. With this manual, the standard SD167060B drivers
have inputs that accept 5 to 24Vdc signals without the need for an external resistor and they replace the
SD17060B-24 in all applications. See Appendix B on page 19 for more information.
The SD17060B, SD17060B-03 and SD17060B-25
The SD17060B, SD17060B-03, and SD17060B-25 micro-stepping drivers are part of the growing line of
motion control products from AMCI. They are designed for use with a variety of stepper motors including
AMCI’s size 23 through size 34 motors. The three drivers can be programmed to a maximum resolution of
50,800 steps per turn and output a motor current of 1.0 to 6.3ARMS that is programmable in 0.1ARMS increments.

 SD17060B and SD17060B-03 digital inputs accept 5Vdc to 24Vdc without the need of an external current
limiting resistor
 SD17060B-25 digital inputs will work with 24Vdc only
Common features of the three drivers include:
 Inputs that accept 5Vdc to 24Vdc without the need of an external current limiting resistor
 Anti-Resonance Circuitry
 Back-EMF Protection Circuity
 Programmable Idle Current Reduction
 Programmable Current Loop Gain
 Programmable Pulse Train Input (Step/Direction or CW/CCW)
 Programmable Active State for the Disable Input
Most of the information in this manual applies to all three drivers and the “SD17060B” part number is used to
refer to all three. When giving information that only applies to the SD17060B-03 or SD17060B-25, the complete
part number, i.e. “SD17060B-25”, is used.
SD17060B-03
The SD17060B-03 differs from the other two drivers in the way it controls the Fault Output.
On all SD17060B units, (including the -03 and -25), the Fault Output conducts when the unit is operational,
and turns off when there is a fault. This way, a loss of power will appear as a fault.
On the SD17060B and SD17060B-25 units, the Fault Output will be off if the driver is disabled on power up.
On the SD17060B-03, if the driver is disabled on power up, the Fault Output will be on and stay on until the
drive is enabled. At this point, the SD17060B-03 runs its self checks and determines the proper state for the
Fault Output.
