Description
ICS TRIPLEX T8451C Pulse Frequency Module
T8451C in the control software to set up a total number of pulses and pulse frequency can be controlled pulse signal generator; for lower frequency control pulse, you can use the PLC timer composition, as shown in Figure 2. The pulse frequency can be controlled by the timing constant of the timer to control the pulse period, and the total number of pulses can be controlled by setting a pulse counter C10.
When the number of pulses of T8451C reaches the set value, the counter C10 operates to cut off the pulse generator circuit, so that it stops working. The stepping motor of the servo mechanism stops running when there is no pulse input, and the servo actuator is positioned. When the displacement speed of the servo actuator is required to be high, the high-speed pulse generator in the PLC can be used. The frequency of high-speed pulses of different PLCs can reach 4000-6000 Hz. For general servo mechanisms in automatic lines, their speed can be fully satisfied.
