AC servo systems
Three-phase, 400 VAC
*1 Connect when using an absolute encoder. When the encoder cable for the battery case is connected, do not connect a backup battery.
*2 Normally short B2 and B3. If the internal regenerative resistor is insufficient, remove the wire between B2 and B3 and connect an external
regenerative resistor between B1 and B2.
*3 For servo ON, connect to safety device and set wiring to enable safety function. When not using the safety function, use the servo drive with
the plug (JZSP-CVH05-E, provided as an accessory) inserted into the CN8.
*4 It is the user’s responsibility to obtain 24 VDC power supply.
