NEMA Type 1
NEMA Type 1 SED2s include gland plates (frame sizes A through C)
and protection shields. An enclosure with a NEMA Type 1 rating is
intended for indoor use, primarily to provide a degree of protection
against contact with the enclosed equipment or for locations where
unusual service conditions do not exist. NEMA Type 1 enclosures
protect the operator from electric hazard and protect the equipment
from falling material.
NEMA Type 12/IP54
IP54 is a European enclosure rating; there is no equivalent North
American rating, although it exceeds the NEMA Type 12 rating. An
enclosure with a NEMA Type 12 rating is intended for indoor use,
primarily to provide a degree of protection against dust, falling dirt,
and dripping non-corrosive liquids. An enclosure with an IP54 rating is
protected against dust (limited ingress, no harmful deposit) and it is
protected against water sprayed from all directions (limited ingress
permitted).
OFF1
The OFF1 command stops the SED2 within the selected ramp-down
time (P1121).
OFF2
The OFF2 command causes a free coasting of the motor to a
standstill (impulses for the power section of the SED2 are disabled).
OFF3
The OFF3 command is a secondary controlled ramp-down (P1135).
Default is five seconds.
Overcurrent
A SED2 fault condition that occurs, for example, when motor power is
greater than SED2 power. Also see Fault Code F0001.
Overvoltage
A SED2 fault condition that occurs, for example, when the input line
power is too high or if the motor is in regenerative mode (caused by
fast ramp downs or if the motor id drive from an active load). Also see
Fault Code F0002.
