6. EtherCAT Object Dictionary
Run current is set based on the rated current of the motor. For example, if you use the EzM2-42XL (rated
current: 1.2[A]), the Run current is 8 (80[%]), the control current value while the motor is running is as
follow.

This value related to the torque during operation of the motor. If this value is high, torque during operation
will increase. Therefore, if you think that the torque is insufficient, increase the value of this parameter
to increase the torque.
Information
• If Run current value is high, the heating temperature of a motor can be increased. So please
be careful.
• The maximum setting of Run current(150%) is limited to 4[A]. 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.
• Run current is set automatically as load. Therefore use only when torque value during running
is insufficient.
Information
This object can NOT be set while it’s ’Operation Enabled’ state. Please set after ’Operation Disable’.

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.
