Ac Power, Fuses And Filter; Brake Resistor (Optional); Motor U V W Outputs - ABB MicroFlex e150 Guía De Instalación Rápida

6 Quick Installation Guide – MicroFlex e150


AC power, fuses and filter

MicroFlex e150 can accept supply voltages of 105-250 V AC 50/60 Hz,
1-phase or 3-phase.
For three phase supplies, connect phases to L1, L2 and L3.
For single phase supplies, connect supply to any two line inputs, for
example L1 and L2.
The AC supply must incorporate a circuit breaker (or fuse) and the
specified filter. For ideal earthing, mount filter on the same metal surface
as MicroFlex e150. Protective earth must be connected to the
MicroFlex e150 case using an M4 screw in the top of the metal heat
sink.


Brake resistor (optional)

A suitable brake resistor may be required to dissipate excess power
from the internal DC bus during motor deceleration.
The brake resistor must have a resistance of at least 39 Ω, inductance
of less than 100 μH, and a power rating suitable for the application.
Suitable resistors are listed in manual MN1961WEN. Connect the brake
resistor to R1 and R2.


Motor U V W outputs

Connect the motor to the U, V and W outputs.
The U, V and W outputs must be connected to their corresponding U, V
or W terminal on the motor. Mis-connection may result in uncontrolled
motor movement.
Motor earth should be connected to the MicroFlex e150 case using an
M4 screw in the top of the metal heat sink.
The motor cable shield should be connected using a conductive
earth/ground clamp, attached to the same metal surface as the
MicroFlex e150.
