Troubleshooting of LED display and status register faults
DIAS Drive has two LEDs that display the amplifier status. The combination of green and red LED indicates that the controller is in boot mode (firmware is damaged or unavailable); Green 1 Hz flashing and red Off indicate readiness to start; Green 8 Hz flashing and red Off indicate that the output current is limited by the I ² T value (one or more axes); Green On and red Off indicate operation; Green On and red 1 Hz flashing indicate a warning; Green Off and red On indicate errors. These LEDs are first-hand information for quickly determining the status on site.
I-STATUS can read 32-bit state variables, which contain all error and status information. The amplifier function can be changed by setting the corresponding bits through the G-MASKE1, G-MASKE2, G-MASKW, and G-MASKD commands. According to the mask setting, the amplifier detects errors, warnings, or no response. Error bits include: bit 0 for single-phase operation, main power supply voltage is only single-phase, check amplifier fuses and electrical connections; Bit 1 main voltage supply error. The amplifier is enabled when the main voltage is not applied. Check the main power fuse, electrical power supply, and enable before loading the DC bus voltage; Bit 3 DC overvoltage, internal/external regeneration resistor not connected, internal resistance defect, external resistance defect, connect regeneration resistor, replace amplifier or external resistor; Bit 4 DC undervoltage, enabling the main voltage supply of the amplifier to be too low, disabling the amplifier before the DC bus voltage falls below the undervoltage threshold set by G-VBUSM; Position 6 holding brake error, no holding brake connection but M-BRAKE=1, brake cable short circuit, holding brake short circuit, use holding brake motor, check cable, change M-BRAKE to 0; Position 7 brake switch error, internal stop brake switch defect, no holding brake in parameters but M-BRAKE=1, replace amplifier, use holding brake motor, change M-BRAKE=0, check connectors and motor cables; Temperature of motor 9, trigger the motor temperature switch, check if the motor is undersized, if the environmental conditions are poor, if the feedback cable or connector is broken, and check the feedback cable and connector; The ambient temperature is 10 degrees Celsius, and the internal temperature is too high. Improve the ventilation inside the cabinet and check the installation position; Position 11 radiator temperature, radiator temperature is too high, improve ventilation, check installation position; Feedback error at position 12, feedback cable breakage, feedback equipment defect, feedback poor connection, check feedback cable, replace feedback equipment, check connection; Position 13 commutation error, motor phase position error, motor or feedback cable wiring error, check M-ROFF, motor connection, feedback cable; Motor overspeed at position 14, motor phase position error, motor connection error, feedback cable error, overshoot greater than 1.2 × V-NMAX. Check M-ROFF, motor connection, feedback cable, and optimize control loop; Bit 15 drag error, P-PEMAX lag window is too small, increase P-PEMAX and/or optimize control loop; Bit 16 trajectory error, the speed set value calculated from position change is higher than 10000 r/min. Check the P-SCALE and P-SSCALE parameters and controller reference values; 17 host communication, no new preset values for two consecutive cycles, check A-TIME and A-STIME and control cycles, check interface communication, refer to I-DEROR; Position 18 amplifier error E2, various internal errors, refer to I-DEROR, contact the manufacturer; Position 19 amplifier error E1, various internal errors, refer to I-DEROR, contact the manufacturer; Power output error: motor cable grounding, motor grounding, output stage defect, check motor cable, replace motor, replace amplifier; Brake circuit error: Regenerative resistor cable grounding, Regenerative resistor grounding, Regenerative output stage defect, Replace Regenerative resistor cable, Replace Regenerative resistor, Replace amplifier; Bit 20 "Enable Lock" error, the safety input of the software enabled amplifier is still low, and the amplifier is only enabled when ENABLE and EN-BRAKE are high; Bit 21 driver voltage error, software enables amplifier with LOCK still low, only enables amplifier when LOCK signal is high; When the 22 DC overvoltage and regeneration resistor limit are reached, the power of the regeneration resistor is insufficient, and the power of the braking resistor is reached and the resistor is disabled, an external regeneration resistor must be used to adjust the G-MBAL value; Position 23 brake power supply voltage error, maintain brake power supply 24 V-BR missing, maintain brake switch defect. If the motor has maintained braking, the amplifier can only be enabled when 24 V-BR is applied to the brake. Replace the amplifier; Bit 25 I ² T error, I ² T exceeds the warning value A-I2TERR, increase A-I2TERR; 26 motor temperature warning, I-TEMPIM exceeds warning value A-TEMPIW, increase A-TEMPIW; Option 27 motor parameter error, when using EnDAT or HIPERFACE encoders, the M parameter was not found in the encoder, the M parameter was not loaded into the encoder, encoder defects, signal line or connector defects, wiring errors, or cable breakage; Bit 28+circle error, when using EnDAT or HIPERFACE multi circle encoder, an error occurs when expanding beyond 4096 circles. Replace the motor with multi circle encoder and encoder defect; The total power limit is 29, and the power of all axes exceeds the maximum load, resulting in insufficient drive size and reduced load.
