Technical Manual for EA350 Analog Pulse Type Servo Driver V101 1.2.3 Components of the servo driver EA350-0R9, 1R6, 2R5, 4R8 and 6R2 models Digital tube display Operating status of servo with 5-bit seven-segment LED digital tube display Key operator Parameter setting Power source of L1C With reference to the rated voltage on the nameplate, and L2C control enter the power source of the control circuit circuits With reference to the rated voltage on the nameplate, Power source of L1, L2 enter the power source of the main circuit (cabinet A, and L3 main circuits i.e.
0R9, 1R6 and 2R5 model without L3 terminal) The DC bus voltage terminal is used for the driver to P+, share the DC bus A short-circuiting piece is installed between P+ and D in default; upon connection of an external braking P+, D or C to an resistor, remove the short-circuit piece, leave P+ and D external braking open, and connect the external resistor between P+ and resistor C (Size A cabinet, i.e. 0R9, 1R6 and 2R5 models without terminal D) U, V and W servo Connecting the three phases, i.e.
U, V and W of the motor servo motor 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.
Connection terminal of CN5 encoder Encoder connecting to the servo motor EA350-011, 5R6, 8 R5, 013, 017, 022, and 028 models Operating status of servo with 5-bit seven-segment LED digital tube display Digital tube display Operating status of servo with 5-bit seven-segment LED digital tube display Key operator Parameter setting Power source of L1C and L2C control circuits With reference to the rated voltage on the nameplate, enter the power source of the control circuit Power source of L1, L2 and L3 main circuits With reference to the rated voltage on the nameplate, enter the power source of the main circuit P+, P+ and The DC bus voltage terminal is used for the driver to share the DC bus P+, D or C to an external braking resistor A short-circuiting piece is installed between P+ and D in default; upon connection of an external braking resistor, remove the short-circuit piece, leave P+ and D open, and connect the external resistor between P+ and C (Size D cabinet, i.e.
