EA180 Series Servo Drive Users Manual 3.4.4 Digital input terminal connection The digital input (DI) terminal of EA180 series servo drives adopts a full bridge rectifier circuit. The current flowing through the terminal can be either positive (NPN mode) or negative (PNP mode). Taking DI1 as an example, DI1 ~ DI8 interface circuits are identical. 1) When the upper device is relay output: Internal 24V power supply External 24V power supply Fig. 3-8 Wiring of digital input terminals when the upper device is relay output 29 Operating Value Name Function Description mode 12 ALM Alarm output Valid: Alarm occurs P S T 13 Tcmp Torque compliance Valid: Motor output torque reaches set value Invalid:
Motor output torque does not reach set value T 14 Home Homing Valid: Homing completed Invalid: Homing is in progress P 15 S-RUN Servo enable Valid - servo enabled Invalid - servo disabled P S T 27 T CLS _ Torque close Valid: The current percentage of the motor reaches or exceeds the set value of P2-08 (regardless of direction). P S T 29 SPD P _ Speed programming comparison output P8-36 selection judgment logic. When the conditions are met, the output is valid; When the conditions are not met, the output is invalid; 10rpm is used to judge the hysteresis, and the output does not change during the hysteresis. P S T 30 TRQ P _ Torque programming compares output P8-39 selection judgment logic.
When the conditions are met, the output is valid; When the conditions are not met, the output is invalid; 3.0% is used to judge the hysteresis, and the output does not change during the hysteresis. P S T 31 SPD T _ RQ Speed programming compares output Valid: Both SPD P and TRQ P are valid _ _ Valid: SPD P or TRQ P is invalid _ _ P S T Attention☞ 1. The speed judgment generally has 10rpm hysteresis, and the output remains unchanged during the hysteresis. 2. The torque judgment generally has 3.0% hysteresis, and the output remains unchanged during the hysteresis.
