◆ Using the Pulse Train Output
The pulse train output terminal MP can either supply power but can also be used with external power supply. Peripheral
devices should be connected in accordance with the specifications listed below. Failure to do so can cause unexpected
drive operation, and can damage the drive or connected circuits.
■
Using Power from the Pulse Output Terminal (Source Mode)
The high voltage level of the pulse output terminal depends on the load impedance.
Note: The load resistance needed in order to get a certain high level voltage V
MP
can be calculated by:
Figure 3. 33
Figure 3.29 Pulse Output Connection Using Internal Voltage Supply
■ 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.
