Pulse and Direction Connection:
(1)
Optically isolated, high level 3.5-5V or 24V, low voltage 0-0.5V
(2)
Maximum 500 KHz input frequency
(3)
The width of PUL signal is at least 1.0μs, duty cycle is recommended 50%
(4)
Single pulse (step & direction) or double pulse (CW/CCW) is set by DIP Switch SW7
(5)
DIR signal requires advance PUL signal minimum 2 μs in single pulse mode
(6)
The factory setting of control signal voltage is 24V,
