I

Pulse and Direction Connection:

(1) Optically isolated, high level 4.5-5V, low voltage 0-0.5V.

(2) Max 200 KHz input frequency.

(3) The width of PUL signal is at least 2.5μs, duty cycle is recommended 50%.

(4) Single pulse (step & direction), iEM-23xx and iEM-24xx support double pulse

(CW&CCW), while iEM-17xx do not support.

(5) DIR signal requires advance PUL signal minimum 5 μs.

Notes:

(1) Shielding control signal wires is suggested;

(2) To avoid/reduce interference, do not tie control signal cables and power wires together.

Tuning Port P2

The P2 connector in Figure 2 is a RS232 communication port for Leadshine software connection. It is just used to

modify parameter, not for equipment control because neither precision nor stability is sufficient. If you need a

Modbus-RS485 control, use a Leadshine iEM-RS series integrated stepper motor.The interface definition is as

follows:
