6.Connection of Motor
6-1 In the case of Bipolar type motor
6-2 In the case of Unipolar type motor
Wiring method 1: With same current settings as a unipolar microstep driver, the torque and heat that is
generated by a motor are almost the same. Please use this wiring method in usual.
Wiring method 2: It is effective method for using a motor at low speed with high torque. To make motor heat
generation equivalent to wiring method 1, please limit the maximum current to 70%.
However, the torque generated in the low speed range is 1.4 times of usual but an inductance of the coil is
four times than the method 1, a torque drops sharply against an increasing rotation speed.
