u Using the Pulse Train Output
The pulse train output terminal MP can supply power or be used with an external power supply.
NOTICE: Connect peripheral devices in accordance with the specifications. Failure to comply may cause unexpected drive operation, and
can damage the drive or connected circuits.
n Using Power from the Pulse Output Terminal (Source Mode)
The high voltage level of the pulse output terminal depends on the load impedance.

n Using External Power Supply (Sink Mode)
The high voltage level of the pulse output signal depends on the external voltage applied. The voltage must be between 12
and 15 Vdc. The load resistance must be adjusted so that the current is lower than 16 mA.
