SIGMATEK DIAS Drive 310-23 servo amplifier

Common faults and solutions

When the motor rotates clockwise, the I-FPOS decreases: it may be due to incorrect rotation function or incorrect rotation connection. Check the rotary transformer and connect it according to the wiring diagram. Motor not turning: The motor current reaches the limit but there is no torque, and the motor connection is incorrect. Check the U, V, and W connections of the motor terminal board. Motor 'sliding': The motor torque is too low or the direction is different, the M-ROFF is not set correctly, and the motor and/or feedback connection is incorrect. Check the M-ROFF parameters, inspect the motor and feedback connections. The motor stops at certain positions: M-POL and/or M-RPOL settings are incorrect, the motor cable is disconnected, and the motor cable is not connected to all wires. Check M-POL and M-RPOL parameters, replace motor cables, and inspect connections. Motor oscillation: Control gain too high, feedback cable shielding defect. Reduce V-KP and/or P-KV, check the feedback cable and replace it. These troubleshooting steps can help engineers quickly locate mechanical, electrical, and parameter issues.

Maintenance, replacement, and storage

The servo amplifier is maintenance free. Opening the casing will result in loss of warranty. The dirt on the shell can be removed with isopropanol or similar products. Internal contamination of the equipment must be handled by the manufacturer. The fan grille can be cleaned with a dry brush. Spraying or immersion is not allowed. Repairs must be carried out by the manufacturer. When replacing the servo amplifier, turn off the power supply to the control cabinet and remove the fuse. After disconnecting the main voltage supply, wait for at least 5 minutes until the intermediate circuit voltage drops below 40 V before touching conductive components or removing connectors. The temperature of the radiator may exceed 80 ° C, and it should be checked and wait for it to drop below 40 ° C before processing. Unlimited storage time of less than 1 year; Greater than or equal to 1 year, the intermediate circuit capacitor must be restructured before the initial start-up. Disconnect all electrical connections and apply 230 V AC single-phase to the L1/L2 terminals for 30 minutes. The original packaging must be used for transportation to avoid dropping. The storage temperature is -25 to+70 ° C, with a maximum variation of 20 K/h and a maximum humidity of 95% without condensation. According to national electronic waste regulations, it cannot be disposed of as household waste.

VARAN interface and shielding

VAC 013 is a VARAN interface module for DIAS Drive 3xx, integrated into the drive. It includes SS1 and STO safety functions, as well as a digital input interface that can be used as a fast position latch input. The VARAN bus can be configured as a linear structure through the VARAN Out port. The interface includes 1 VARAN In (RJ45, maximum 100 m), 1 VARAN Out (RJ45, maximum 100 m), 1 DIAS Drive interface (26 pin blade terminal), 4 fast digital inputs, 2 safety inputs (SS1 and STO), and 1 relay output for indicating safety function status. Power supply+5 V DC is provided by DIAS Drive, with a typical current of 400 mA and a maximum current of 500 mA. Digital inputs D-IN1 to D-IN4 are typically+24 V and a maximum of+30 V, with signal low ≤+5 V and high ≥+15 V, switch threshold typically+9 V, input current+24 V is 10 mA, and input delay typically 0.1 ms. Safety inputs ENABLE-L and ENABLE-H have a differential voltage of typically 24 V and a maximum of 30 V, with low<+6 V and high>+14 V, opening for about 20 ms and closing for 0.5 to 1 s. The relay outputs one normally open, power supply+24 V DC, switching time<10 ms, switching range maximum 30 V DC/minimum 100 μ A, maximum 0.5. A; maximum 42 V AC/minimum 100 μ A, maximum 0.5 A. Safety integrity level SIL 3, performance level PL e, diagnostic coverage rate 99%, PFH_D 0.29 × 10 ⁻⁹, MTTF-D 8694 years, service life 20 years. The ambient temperature is 0 to+60 ° C, storage is -20 to+85 ° C, humidity is 0 to 95% non condensing, altitude is up to 2000 meters, protection is IP20, and pollution level is 2.

VARAN shielding is recommended to use CAT5e industrial Ethernet cables, S-FTP cables, symmetrical multi wire, unshielded pairs, total shielding using foil and braided combinations, and non laminated variants are recommended. VARAN cables must be fixed at a distance of 20 cm from the connector to prevent vibration. When the control cabinet is connected to the external VARAN component, the shielding should be placed at the entrance of the control cabinet casing. If only IP67 modules and connectors are used for wiring outside the control cabinet, no additional shielding support is required. When wiring inside the control cabinet, it is recommended to connect shields in front of all electronic components. When connecting noise generating components, shielding should be placed before the power element or power element group. When connecting two control cabinets, it is recommended to place a shield at the entrance point of each control cabinet. These measures can effectively suppress electromagnetic interference and ensure stable communication of VARAN bus.
