R7D–AP@H: Single-phase 200/230 V AC (170 to 253 V AC) 50/60 Hz
R7D–AP@L: Single-phase 100/115 V AC (85 to 127 V AC) 50/60 Hz
Note: Only the R7D–AP08H (750 W) has an L3 terminal, enabling three-
phase input: Three-phase 200/230 V AC (170 to 253 V AC) 50/60 Hz
Normally short-circuit between +1 and +2.
If harmonic control measures are required, connect a DC Reactor between +1
and +2.
Do not connect anything.
R7D-AP@H: Single-phase 200/230 V AC (170 to 253 V AC) 50/60 Hz
R7D-AP@L: Single-phase 100/115 V AC (85 to 127 V AC) 50/60 Hz
30 to 200 W: No External Regeneration Resistor can be connected.
400 W: This terminal does not normally need to be connected. If regenerative
energy is high, connect an External Regeneration Resistor between B1 and
B2.
750 W: Normally shorted between B2 and B3. If there is high regenerative
energy, remove the short bar between B2 and B3 and connect an External
Regeneration Resistor between B1 and B2.
Red These are the terminals for outputs to the Servomotor. Be sure to
wire these terminals correctly.
