Carrier D2-3466-2 instruction manual

ATTENTION: When connected to a non-regenerative common DC bus, regeneration may cause a rise in DC bus voltage. Be aware that other drives on the bus may experience an unexpected

!speed increase due to the high bus voltage. Failure to observe this precaution may result in bodily injury.

ATTENTION: The motor shaft can rotate in either direction by up to one (1) revolution, providing minimum torque immediately after the identification procedure (initiated in H.020) has been started. Stay clear of rotating machinery. Failure to observe this precaution could result in bodily injury.

ATTENTION: In V/Hz regulation, if P.000 (Control Source) is set to OP (Option Port), and P.062 is set to 1 (Hold Last Reference), and the drive loses communication with the network, the drive will maintain the last frequency command sent to it. Ensure that driven machinery, all drive-train mechanisms, and application material are capable of safe operation at the maximum operating speed of the drive. Failure to observe this precaution could result in bodily injury.

ATTENTION: Carrier Frequency (P.047) and Current Limit (P.005) must be set correctly before activating the identification procedure (H.020) to avoid motor overloading and/or overheating. Failure to observe this precaution could result in damage to, or destruction of, the equipment.

ATTENTION: The motor can rotate in the reverse direction during the identification procedure (H.020) even if reverse disable has been selected in P.027. Uncouple the motor from any driven machinery that could be damaged by reverse rotation. Failure to observe this precaution could result in damage to, or destruction of, the equipment.
