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:
NOTE
: Enable signal is always high in this drive. Any external supply applied will disable the Drive.
Remark:
a)
t1: ENA must be ahead of DIR by at least 5
µ
s. Usually, ENA+ and ENA- are NC
(normally closed).
b) t2: DIR must be ahead of PUL effective edge by 5
µ
s to ensure correct direction;
c)
t3: Pulse width not less than 2
µ
s;
d) t4: Low level width not less than 2
µ
s.
5. Control Signal Mode Setting
Pulse trigger Edge and Single/Double Pulse Selection Trigger on rising or
falling edge of pulse by PC software ProTuner software or STU debugger. It is also possible
to set single pulse mode or double pulse mode .In dual pulse mode, the signal on the direction
control terminal must be held high or floating.
6. Parameter Self-Tuning Function
If switch SW4 Switched back and forth within 1 second, the driver can auto-
complete the motor parameters and internal parameters adjustment when the conditions like
motor, supply voltage changes, please conduct a self-tuning, otherwise,
the motor may not run normal
NOTE
:-The pulse cannot be input at this time and the direction signal not change.
METHOD 1:-SW4 from on to off and then off back to on in 1 sec
METHOD 2:-SW4 from off to on and on then back to off on 1 sec
NOTE
:-This model has power –on auto tuning function

CALCULATION OF PULSE FREQUENCY
:-
F = (RPM X MICRO STEP)/60
If need 60 RPM at 400 Micro step
Then Frequency = (60x400)/60
= 400Hz
