Typical Connection
A complete stepping system should include stepping motor, stepping driver, power supply
and controller (pulse generator). A typical connection is shown as figure 4.

Sequence Chart of Control Signals
In order to avoid some fault operations and deviations, PUL, DIR and ENA should abide
by some rules, shown as following diagram:
Figure 5: Sequence chart of controlsignals
Remark:
·
t1: ENA must be ahead of DIR by at least 5 s. Usually, ENA+ and ENA- are NC (not
connected). See “Connector P1 Configurations” for more information.
·
t2: DIR must be ahead of PUL effective edge by 5 s to ensure correct direction;
·
t3: Pulse width not less than 1.5 s;
·
t4: Low level width not less than 1.5 s.
