Motor Data
Description: If the motor peak current is less than the capacity of the drive amplifier, the amplifier is
automatically limited to the level of the motor peak current. Parameter 109 motor peak RMS current at rated
(base) speed. For a standard 8720SM motor with Stegmann feedback this value is read from the motor encoder
memory.

Drive Data
Description: The amplifier peak current is limited by the drive hardware, which means that the current for the
maximum attainable torque limit value is fixed as well. This parameter is determined by the drive and can’t be
changed.
