Caution
Make sure that there are no mis-wiring and short-circuiting and do not turn power
on before wiring correctly. There is danger of fire or failure.
Please tighten the terminals with the torque of less than 3.5kgf・cm (0.35N・m).
Please use the wire rod with the cross-section area corresponding to current value.
※In microstep mode, a sine curve current which made effective value the run current value set by
run current adjustment trimmer flows. The maximum current value which runs on the lead wire
of motor is run current × 2 .
ex.) Run current: 3A → Max. current value is 4.2A. ( 4.2(A)2(A)3 =× )
Use twisted wire pair for the signal input wiring. Please tighten the terminals less than 3.5kgf・cm
(0.35N・m). (Proper torque is 2.5kgf・cm (0.25N・m))
