The FR-A840-00620-2-60 is fully backwards compatible with the legacy FR-A740-00620 series parameters. By utilizing the FR-Configurator 2 software suite, users can migrate parameters without manual re-entry. Note, however, that physical footprint and terminal block locations differ slightly; ensure mounting panels accommodate the depth variance of 190 mm.
When deploying this drive in constant-torque configurations at low frequencies (below 6 Hz), standard self-cooled motors will experience high heat generation due to reduced fan speed. In these scenarios, a motor with an independent cooling fan (forced ventilation) is required. Ensure the drive enclosure maintains a 100 mm top and bottom clearance for unrestricted heat sink airflow.
For reliable RS-485 or SSCNet communication, control wiring must use twisted-pair shielded cables separate from the power cables. Keep the control wiring separated from the main circuit wiring by at least 10 cm to prevent high-frequency electromagnetic interference. Connect the shield braid directly to the ground plate rather than using a pigtail connection.
Hazardous voltages remain present in the internal DC bus capacitors even after mains power is disconnected. Wait a minimum of 10 minutes after complete de-energization, and verify with a multimeter that the DC bus voltage (terminals P/+ to N/-) has discharged below 50VDC before initiating physical contact with terminal wiring.
Mount the inverter vertically on a flat, non-flammable vertical wall using M6 size mounting bolts. Avoid tilted installations to ensure optimal thermal chimney-effect dissipation.
Connect the protective earth (PE) ground wire to the designated ground terminal before routing primary three-phase lines to the R/L1, S/L2, and T/L3 terminals.
Ensure the terminal cover is securely locked back into place before switching on the primary input breaker to perform initial parameters verification.
