The SD17060B is configured by DIP switches on the top of the driver. The factory default setting has all

switches in their off (0) position except for SB2-1. (CurrentLoop Gain = 1) All switch setting are latched.

You must cycle power to the driver before changes take effect.

Note on Idle Current Reduction

The SD17060B controls the

RMS current through the motor.

Therefore it can momentarily

put 1.4 times the motor's rated

current through the windings

safely. If you choose a setting

of No Reduction, the

SD17060B will revert to peak

current control when the motor

is not turning. This feature pro-

tects the motor from damage.

You will not see a reduction in

holding torque.

Disable Input

You can program the Disable Input's

active state. When Active High, you

must apply power to the input to disable

the driver. When Active Low, you must

apply power to the input to enable the

driver. If you are not using the input, set

this switch to Active High and the driver

will operate as you expect. When the

Disable Input is active, the SD17060B

removes power from the motor and stops

accepting indexer pulses. Over-temp and

Over-current faults are cleared when the

driver transitions from a Disabled state.

Anti-Resonance

Allows the SD17060B to compensate for

back-EMF generated by the motor. It

should be left enabled for most applica-

tions. Disable only if you are sure you do

not want this feature or under the advice of

AMCI tech support.

Current Loop Gain

This setting allows you to compensate for 

variations in motor properties which will give you smoother motion and better positional

accuracy. See the

Self-Test Mode

Self-Test mode is controlled by the switch SB4-1. If you change the state of this switch

while power is applied to the SD17060B, the driver will respond by rotating the attached

motor clockwise at 60 RPM with a resolution of 50,000 steps per turn. Note that changing

this switch does not alter the current supplied to the motor. All switch settings are read and

latched on power up. However, you must return this switch to its correct setting for normal

operation before cycling power or resetting the SD17060B.
