Figure 3-8 Sample of Motor Current Control
Drive the motor at Im (approx. 275 mA) during the start-up step and the stop step. Do not switch the
current.
Continuous driving
When the motor is driven for a long time or motor drive is often performed repeatedly, the motor heats
up and may not be able to show necessary performance. To avoid it, when the motor was driven, set
up the pause time of the same period of time as that the motor was driven. Furthermore, make one-
time continuous driving 6 minutes (max.).
