Output Connections - WEG CFW701 Manual Del Usuario

Installation and Connection
Set P0151 and P0185 to their maximum values (400 V or 800 V) when using dynamic braking.
„
The DC link voltage actuation level of the dynamic braking is set by parameter P0153 (Dynamic
„
Braking Level).

ATTENTION!
The inverter has an electronic motor overload protection that shall be adjusted
„
according to the driven motor. When several motors are connected to the
same inverter, install individual overload relays for each motor.
The motor overload protection available for the CFW701 is in accordance
„
with UL508C as per the following information:
- Trip current equal to 1.25 times the motor rated current (P0401) adjusted
in the oriented start-up menu.
- The maximum value of P0398 (Motor Service Factor) is 1.15.
- Parameters P0156, P0157 and P0158 (Overload Current at 100 %,
50 % and 5 % of the rated speed, respectively) are automatically adjusted
when the parameters P0401 (Motor Rated Current) and/or P0406 (Motor
Ventilation) are changed on the "Oriented Start-up" menu. If the parameters
P0156, P0157 and P0158 are set manually, the maximum allowed value
is 1.05 x P0401.
