This Object sets the current value (Boost current) to be added when the motor accelerates or decelerates.

Boost current is applied propotional to the value of Run current. For example, if you use the EzM2-42XL
(rated current: 1.2[A]), the Run current is 8 (80[%]) and the Boost current is 1 (50[%])), the control current
value during acceleration or deceleration is as follow.

Boost current is a setting that improves the accel./decel. characteristics by increasing the current sup-
plied to the motor in case the accel./decel. time cannot be set sufficiently. Boost current only applies to
acceleration and deceleration.
Information
• If Boost current value is high, the heating temperature of a motor can be increased. So please
be careful.
• The control current is limited to 4[A] same as Run current. Therefore, a motor(56mm, 60mm)
that rated current value exceeds 2.7[A] will not increase as much as the set value even if the
set value is raised.
Information
This object can NOT be set while it’s ’Operation Enabled’ state. Please set after ’Operation Disable’.

The drive adjusts the motor’s drive current from Stop current to Run current according to the size of the
load. This setting is used to reduce heat generation when the motor is stationary or when the load is
light.
