R88D-WTjH(H) (30 to 1500 W)
Single-phase 200/230 V AC (170 to 253 V), 50/60 Hz
R88D-WTjH (500 W to 6 kW) R88D-WTjH (500 W to 6 kW)
Three-phase 200/230 V AC (170 to 253 V), 50/60 Hz
R88D-WTjHL (30 to 200 W)
Single-phase 100/115 V AC (85 to 127 V), 50/60 Hz Single phase 100/115 V AC (85 to 127 V) 50/60 Hz
R88D-WTjHF (0.5 to 15 kW)
Three-phase 380/480 V AC (323 to 528 V), 50/60 Hz
Do not connect anything to these terminals.
(Only the R88D-WT60H has this terminal.)
Normally short between ¨1 and ¨2.
When harmonic control measures are required, connect a DC Reactor be-
tween ¨1 and ¨2.
(The R88D-WT60H does not have these terminals.)
Do not connect anything to these terminals.
R88D-WTjH(H)
Single-phase 200/230 V AC (170 to 253 V), 50/60 Hz
R88D WTjHL R88D-WTjHL
Single-phase 100/115 V AC (85 to 127 V), 50/60 Hz
R88D-WTjHF
24 V DC
30 to 400 W: These terminals normally do not need to be connected. If there
is high regenerative energy, connect an External Regeneration Resistor be-
tween B1 and B2. tween B1 and B2.
500 W to 5 kW: Normally short between B2 and B3. If there is high regenera-
tive energy, remove the short bar between B2 and B3 and connect an Exter-
nal Regeneration Resistor between B1 and B2. nal Regeneration Resistor between B1 and B2
6 to 15 kW: Connect an External Regeneration Resistance Unit between B1
and B2.
These are the output terminals to the Servomotor. Be careful to wire them p
correctly.
This is the ground terminal. Ground to a 100 Ω or less.
