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.

Using Power from the Pulse Output Terminal (Source Mode)
The high voltage level of the pulse output terminal depends on the load impedance.

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.

Terminals A1, A2, and A3 Input Signal Selection
Terminals A1, A2, and A3 can be used to input either a voltage or a current signal. Select the signal type using jumper S1 as
explained in Table 3.13. Set parameters H3-01, H3-05, and H3-09 accordingly as shown in Table 3.14.
Note: If terminals A1 and A2 are both set for frequency bias (H3-02 = 0 and H3-10 = 0), both input values will be combined to create the frequency
reference.
