A-B MicroLogix 1500
Many customers have started to use the Allen-Bradley MicroLogix 1500 as an indexer. The MicroLogix 1500
has a Pulse Train Output (PTO) Instruction that can be used to generate directional pulses to the SD17063.
This instruction controls one output that generates the STEP pulses while your ladder logic controls an output
that selects the DIRECTION.
Outputs on the MicroLogix 1500 must be 24 Vdc. You can wire the outputs as either sinking or sourcing and
you must use the 3.9KΩ resistor as shown in figure 5.4. With the directional pulses being in the STEP&DIR
format, the SD17063’s Pulse Train DIP switch, SB1-1, should be set to one when using the MicroLogix 1500.

Disable Input Wiring
The ±Disable Input on the SD17063 will shut off motor current when active. The circuitry of this input is
identical to the directional pulse inputs. Refer to figures 5.3 and 5.4 when wiring this input. A momentary or
SPST switch can be used in place of the open collector output shown in figure 5.4.
Do not activate the Disable Input while the motor is running. When the Disable Input
is active, the current to the motor is removed, and the motor is free to rotate. No hold-
ing torque is available while the Disable Input is active.
The SD17063 does not accept directional pulses while the Disable Input is active. Therefore, when the Dis-
able Input is turned off, the drive restores current to the motor in the same phase relationship that existed
before the Disable Input was turned on. If the motor rotated while the Disable Input was active, (which is
possible, because there is no holding torque), the motor may not start up correctly.
The SD17063 immediately drops the motor current to zero when the Disable Input is activated, but “ramps
up” the current when the Disable Input is released. This ramp up time lasts for a maximum of 275 millisec-
onds. Directional Pulses are not accepted until the current ramp up is complete. If you send directional
pulses to the SD17063 before the 275 milliseconds have expired, the drive shows a Window Step Violation
fault. The Motor Fault LED will blink to indicate this fault but the drive will still operate and accept direc-
tional pulses. For more information on the Window Step Violation, refer to Minor Faults on page 14.
