Function
R88D-KNxH-ML2 (2 kW) :
3-phase: 200 to 230 VAC (170 to 253 V) 50/60 Hz
Note. Single-phase should connect to L1 or L3.
R88D-KNx-ML2 : Single-phase 200 to 230 VAC (170 to 253 V) 50/
60 Hz
Function
Phase U These are the output terminals to the Servomotor.
Be sure to wire them correctly.
Phase V
Phase W
Function
Normally B2 and B3 are short-circuited.
If there is high regenerative energy, remove the short-circuit bar
between B2 and B3 and connect an External Regeneration
Resistor between B1 and B2.
Do not connect.
