Function
AC power input terminals for the main circuit
Note: for single-phase servo drives connect the power supply input to L1 and L3.
AC power input terminals for the control circuit
(for 200V single/three-phase servo drives only).
DC power input terminals for the control circuit
(for 400V three-phase servo drives only).
Connect an external regenerative resistor between B1 and B2.
Servo drives from 750W to 5 kW: short-circuit in B2 and B3 for internal regenerative resistor. If the
internal regenerative resistor is insufficient, connect an external regenerative resistor between B1 and
B2 and remove the wire between B2 and B3.
Terminals for outputs to the servomotor.
The signal name shows the factory setting. The function can be
changed by parameter setting.
The function of input signals allocated to pins 5 and 7 to 13 can be changed with these options by
parameters settings.
The function of output signals allocated to pins 1,2, 25 and 26 can be changed with these options by
parameters settings
