P1 – Control and Digital Output Connections
The P1 connector in Figure 2 contains connections for control signals and 2 digital outputs.See the following
table for details.
PIN I/O Details
PUL+ (CW+) I
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, must need to set S3 (figure
2) if it is 5V
PUL- (CW-) I
DIR+ (CCW+) I
DIR- (CCW-) I
ENA+ I
Enable Signals: Optional.
(1) Effective high level is 3.5-24V; Effective low level is 0-0.5V connection
(2) ENA signal requires advance DIR signal minimum 200ms in single pulse mode,
(default no connection)
ENA- I
ALM O
Alarm: They takes a sinking or sourcing 100mA current at 5-24V. Max 30VBrake:
Max. 24/100mA, connect with brake coil, relay and diode.
