Connection Pin Assignments And Led Indication; P1 - Control Connector And Fault Output; P2 - Power Connector - Leadshine Technology EM532MINI User Manual

3. Connection Pin Assignments and LED Indication

The EM532MINI has 3 terminal block connectors P1, P2 and P3, 1 DIP switch selectors S1. P1 is for control signal
and fault output connections, P2 is for power connection, P3 is for motor connection.

3.1 P1 - Control Connector and Fault Output

PIN
PUL+
Pulse and Direction Connection: (1) Optically isolated, high level 4.5-5V, low voltage 0-0.5V.
PUL-
(2) Maximum 1 MHz input frequency. (3) Pulse width of 0.5μs or longer. (4) DIR signal requires
DIR+
advance PUL signal 1 μs at least. (5) When the control voltage is 24V, 2K resistors are required.
DIR-
Enable Connection: Optional. (1) Optically isolated, differential. (2) Disable the drive by 4.5-5.0V
ENA+
input connection; enable the drive by 0-0.5 VDC connection(default no connection).
(3) ENA signal requires advance DIR signal 200ms at least. (4) When the control voltage is 24V, a
ENA-
2K resistor is required.
Fault Output Connection: Optional. (1) Maximum 24V/100mA output when over-voltage and
ALM +
over-current error protections activated. (2) Sinking or sourcing. (3) The resistance between ALM+
and ALM- is low impedance as default, and will change to high when the drive goes into error
ALM-
protection.
!
Notes: (1) shield cables are required for P1; (2) don't tie P1&P2 cables and P3 cables together.
