WARNING! Sudden Movement Hazard. Ensure holding brake circuits are properly configured, load equipment may fall or drop during
power loss or drive fault, which could result in death or serious injury.
・ Provide a separate holding brake if necessary.
・ Always construct the external sequence to confirm that the holding brake is activated in the event of an emergency, a power failure, or
an abnormality in the drive.
・ When using the drive with an elevator, provide safety measures on the elevator to prevent the elevator from dropping.
NOTICE: Equipment Hazard. Separate motor and/or braking circuit wiring (terminals, U/T1, V/T2, W/T3, +3, +2, +1,(-), B1, B2, from all
other wiring. Place motor wiring within its own conduit or cable tray with appropriate divider, and use shielded motor cable where
appropriate. Improper wiring practices could result in malfunction of drive due to electrical interference.
NOTICE: Inadequate wiring could result in damage to the drive. Install adequate branch circuit short circuit protection per applicable
codes. The drive is suitable for circuits capable of delivering not more than 100,000 RMS symmetrical amperes, 240 Vac maximum
(200 V class), 480 Vac maximum (400 V class), and 600 Vac maximum (600 V class).
NOTICE: When the input voltage is 440 V or higher or the wiring distance is greater than 100 meters (328 ft.), pay special attention to
the motor insulation voltage or use a drive rated motor. Failure to comply could lead to motor insulation breakdown.
Note: Do not connect AC control circuit ground to drive enclosure. Improper drive grounding can cause control circuit malfunction.
NOTICE: The minimum load for the multi-function relay output MA-MB-MC is 10 mA. If a circuit requires less than 10 mA (reference
value), connect it to a photocoupler output (P1-C1, P2-C2). Improper application of peripheral devices could result in damage to the
photocoupler output of the drive.
