1
Red/1
OUT
Step (+)
Differential output. Step (pulse) output to the drive. Step + signal is active high.
Signal levels: Low
≤
1.0VDC @ -30mA, High
≥
3.5VDC @ +30mA.
2
Green/2
OUT
Direction (+)
Differential output. High signal on Dir specifies motion in the positive
direction; Low signal on Dir specifies motion in the negative direction.
Signal levels: Low
≤
1.0VDC @ -30mA, High
≥
3.5VDC @ +30mA.

In-Position
Used for digital servo drives to indicate that the motor has reached the target
position. HCMOS switching levels (Low
≤
1.0V, High
≥
3.25V). Voltage range: 0-5V.
5
Yellow/9
IN
Drive Fault
An active-high (current not flowing) signal that tells the AT6n00 a drive has faulted.
HCMOS switching levels (Low
≤
1.0V, High
≥
3.25V). You can use the
DRFLVL
command to change the active level to low (current flowing) if desired. NOTE: The
Drive Fault input will not be recognized until the input functions are enabled with the
INFEN1
command.

Black/14
IN
Step Return (-)
Differential output. Step (pulse) output to the drive. Step - signal is active low.
10
White/15
IN
Direction Return (-)
Differential output. Low signal on Direction - specifies motion in the positive
direction; High signal on Direction - specifies motion in the negative direction.
11
Blue/16
OUT
Shutdown (+)
Differential output. This signal is used to turn off current in the motor windings.
High
signal on Sh indicates the motor winding current should be off.
Signal levels: Low
≤
1.0VDC @ -30mA, High
≥
3.5VDC @ +30mA.
12
Purple/17
IN
Shutdown Return
(-)
Differential output. This signal is used to turn off current in the motor windings.
Low
signal on Shutdown - indicates the motor winding current should be off.
