Driver Connectors, P1 and P2
The following is a brief description of the two connectors of the driver. More detailed descriptions
of the pins and related issues are presented in section 4, 6, 8, 9.

Functions
1
Pul

(+5V)
2
Pul
﹣
(pulse)
Pulse signal: in single pulse(pulse/direction) mode, this input
represents pulse signal, effective for each upward – rising edge; in
double pulse mode (pulse/pulse) this input represents
clockwise(CW)pulse. For reliable response, pulse width should be
longer than 3
υ
s.
3
Dir
﹢
(+5V)
Direction signal: in single-pulse mode, this signal has

(Dir)
low/high voltage levels, representing two directions of motor
rotation; in double-pulse mode (set by inside jumper JMPI), this
signal is counter-clock (CCW) pulse,
effective on each rising edge. For reliable motion
response, direction signal should be sent to driver 2
υ
s
before the first pulse of a motion direction reversal.
5
Ena+(+5V)
Enable signal: this signal is used for enable/disable, high

Ena- (Ena)
level for enabling driver and low level for disabling driver.
Usually left unconnected(enabled).
* For the European Market – the maximum input voltage must be limited to 70VDC to comply with CE regulations.
