CL57T(V4.0) Closed-Loop Stepper Drive
3. Connections and LED Indication
A CL57T(V4.0) closed loop stepper drive has 4 connection blocks from P1 to P4 (see figure 2).
Figure 2: CL57T(V4.0) connectors
3.1 P1 – Control and Digital Output Connections
The P1 connector in Figure 2 contains connections for control signals and 2 digital output.
See the following table for details.
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
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)
Alarm : They takes a sinking or sourcing 100mA current at 5-24V. Max 30V
Brake : Max. 24/100mA, connect with brake coil, relay and diode.
