Note: 1. Be sure to connect a current limiting resistor;

2. The maximum allowable voltage and current of the internal optocoupler circuit of the

servo driver are as follows:

Voltage: DC30V (maximum)

Current: DC50mA (maximum)

3.4.2 Position command input signal

Table 3-6 Correspondence between pulse input frequency and pulse width

Pulse mode

Maximum frequency（HZ） Minimum pulse width（us）

Ordinary Differencial

Note: The pulse width of the host computer can't be less than the minimum pulse width, otherwise the

driver may receive the pulse error.

1） Ordinary pulse command input

a） Differential mode

b） When the collector is open

① Use the internal 24V power supply of the drive
