*1 B3-B2 are short-circuited. If the internal regenerative resistor is insufficient, remove the wire between B2 and B3 and connect an external regen-
erative resistor between B1 and B2.
*2 Use only when an absolute encoder. If a backup battery is connected, an encoder cable with a battery is not required.
*3 The default values are ZSP (zero-speed detection) for OUTM1 and T-LIMIT (at torque limit) for OUTM2.
