Differences between EO42 and EC42:
1. EO42 is Ethercat, Open Loop; EC42 is Ethercat, Closed Loop.
2. Different DIP switches: EO42 requires SW6 to be switched down (ON for open loop), while EC42 does not.
3. EO42 does not require a lead wire; EC42 requires an additional lead wire.
Ethercat communication terminal:
The Ethercat cable for the Ethercat bus should not exceed 100 meters in length. It is recommended to use Category 5e 100 Mbps Ethernet cable with dual shielding or higher-grade cables.

GND |
7 |
Provide DC voltage to the negative of motor encoder |
|
5V |
8 |
Provide 5V DC voltage and 100mA current to the motor encoder. |
(1) The encoder power supply is provided by the driver internally at 5V, but it is necessary to pay attention that if the polarity of the encoder power supply line is reversed, the stepper motor or the driver will be damaged.
(2) The encoder generates a 5V differential signal, which is processed internally by a differential chip and then sent to the main controller. The interface voltage here is only 5V, and exceeding 5V will damage the stepper driver.

Default input ports: IN0, IN1, IN2, IN3
IN0-: Negative limit (corresponding to Bit0 in parameter 0x60FD)
IN1-: Positive limit (corresponding to Bit1 of parameter 0x60FD)
IN2-: Origin (corresponding to Bit2 of parameter 0x60FD)
IN3-: Reserved
Default output ports: OT0, OT1
OT0+: Alarm output
OT1+: Position output (default) / Brake output (brake wiring diagram shown below
Output port note:
(1) The external power supply is provided by the user, but it is necessary to pay attention that if the polarity of the power supply is reversed, the stepper driver will be damaged.
(2) The output is a collector open circuit configuration with a maximum current of 50mA and an external power supply voltage of 25V. Therefore, the load of the switch output signal must meet these specifications. Exceeding these limits or directly connecting the output to the power supply may damage the stepper driver.
(3) If the load is an inductive load such as a relay, a reverse parallel current flow diode must be connected across the load. If the current flow diode is connected in reverse, the stepper driver will be damaged.
