FL20-CA Series
Function
Connect 3-phase 220V input power
Connect 1-phase 220V power supply between L1 and
L3.
(2kW and above drive only connects to 3-phase power
supply)
Connect any 2 phase in 3-phase power supply or
single-phase power supply.
Terminals are shorted by default. Use built-in brake
resistor. (built-in braking resister for the drive of M2
and above cover)
Normally no need to connect.
If built-in braking capacity is insufficient, remove the
jumper between B2 and B3, and connect external
braking resistor between B1 and B2.
Terminals are shorted by default.
Connect DC reactor between both terminals when
restraining power harmonic.
Connect to servo motor.
The servo drive must be grounded.
Function
Connect 3-phase 380V input power supply
(R, S, T are the main circuit power input terminals of
M4 and above drives )
Disabled
Terminals are shorted by default. Use built-in brake
resistor. (no built-in braking resistor for 7.5kW and
above drives)
Normally no need to connect.
If the built-in braking capacity is insufficient, remove
the jumper between B2 and B3, connect external
braking resistor between B1 and B2.
Forbidden to ground or connect to zero line.
Connect to servo motor.
