1.Power input and Communication port

2.Control signal port

3.Status indication

PWR: power indicator light. When power is on, the green indicator light is on.

ALM: fault indicator light.

Flashing red light once within 3 seconds: over-current or phase-to-phase short circuit fault;

Flashing red light 2 times continuously within 3 seconds: over-voltage fault;

Flashing red light 7 times continuously within 3 seconds: position error alarm.

DIP switch setting

ESS42R uses a 5-bit DIP switch to set the drive station number and communication baud rate.

SW1~SW3: Drive station number setting. SW4: Drive communication baud rate. After the slave number and communication baud rate are modified, it needs to be powered on again to take effect.

Note: The slave station number setting, when it is in the default file, can define the slave station number by setting the custom drive slave station number register (0x0020), the range is 1~31.

Note: When the communication baud rate is set to 9600bps, the serial data format is fixed to 8 data bits, no parity, and 1 stop bit. When set to other three baud rates, the serial port data format is determined by the serial port data format register (0x0021).

SW5: RS485 terminal resistor. The bus end driver needs to set this dip switch to ON, and the other drivers need to set it to OFF.
