Technical Manual for EA350 Analog Pulse Type Servo Driver V101 EA350-038, 052 and 062 models 10 C braking resistor terminal External braking resistor connected to P+ L1, L2, L3 power sources With reference to the rated voltage on the nameplate, enter the power source of the main circuit P+ Positive DC bus terminal The positive DC bus terminal of the drive, used for the driver to share the DC bus and connect the external braking resistor with C terminal.
CN1 analog monitoring signal terminal Two channels of analog output Digital tube display Operating status of servo with 5-bit seven-segment LED digital tube display Key operator Parameter setting CN6USB communication terminal MICRO USB communication terminal CN2 and CN3 communication terminals The two terminals are connected internally in parallel, with RS232, RS485 and CAN communication interfaces CN4 control terminal Connection to upper controller PE ground terminal To ground of power source and servo motor CHARGE Bus voltage indicator light It is used to indicate whether the bus capacitor is in the charged status.
When it is on, charge is present with the capacitor in the driver even if the main circuit is powered off. U, V and W servo motor Connecting the three phases, i.e. U, V and W of the servo motor Negative DC bus terminal The negative DC bus terminal of the drive, used for the driver to share the DC bus PE ground terminal To ground of power source and servo motor
