1. Introduction
ACE-102 is a high voltage/current microstep driver. It is suitable for motor sizes
NEMA 23 and NEMA 34 2-phase bipolar stepper motors. It accepts both DC and
AC voltage input.
1.1 Feature Highlights
- 24 to 80 VDC input
- 24 to 60 VAC input
- Max Current: 6.2 A (RMS), 8.7A (Peak)
- Current Settings (RMS): 2.5A, 2.7A, 2.9A, 3.0A, 3.5A, 3.7A, 3.9A,
4.2A, 4.4A, 4.6A, 4.8A, 5.0A, 5.3A, 5.7A, 6.0A, 6.2A
- Micro-step Settings: 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 64, 80,
100, 200.
- Maximum pulse rate support of 300K pulses/second
- Configurable as one-clock (Pulse/Dir) or two-clock (CW/CCW)
operation
- Auto-current reduction (50%) during after idle time of 1.5sec to
increase efficiency
- Auto-run feature for testing without a controller. Fixed speed of 30
RPM.
- Opto-isolated differential support for Pulse/Dir or CW/CCW
- Opto-isolated differential enable input
- Alarm LED for open/short and over-temperature conditions
- Auto-shut down for open, short and over-temperature fault conditions

3.3. Pulse/Dir/En Inputs
ACE-102 supports both one-clock (Pulse/Dir) or two-clock (CW/CCW) inputs.
One-clock uses Pulse signal as the amount of movement and Dir signal as the
direction of the movement.
Figure 3.2
Two-clock uses CW as clockwise movement and CCW as counter clockwise
movement.
Figure 3.3
Depending on the direction polarity setting, actual direction of the stepper motor
rotation can be configured for the application.
Maximum pulse rate support is 300K pulses/second.
Pulse/Dir (CW/CCW)/Ena inputs are opto-isolated differential inputs with 220
Ohm resistor. 5V is recommended. If voltage across is greater than 5V, make
sure to add current limiting resistor to limit the current across the diode.
