PLC S7-300 – PWM – DC SERVO MOTOR

PLC S7-300 – PWM – DC SERVO MOTOR

B.O.M including:
1. CPU 314C-2DP.
2. L298N – DUAL H-BRIDGE DRIVER
3. DC SERVO MOTORS (NISCA NF5475, in my case).
4. POWER SUPPLY 5V & 24V.
5. SOME SWITCHES TO CONTROL DIRECTION
This demo is based on integrated PWM function in CPU314C-2DP. To control pulse width modulation via the user program, we use SFB 49 “PULSE”. The following operations are available:
* Starting/stopping via software gate SW_EN
* Enabling/controlling the output DO
* Retrieving the status bits STS_EN, STS_STRT and STS_DO
* Input of the output value
* Jobs for reading/writing the registers
Two motors are controlled separately through L298N Dual H-Bridge Module. Their speed can be adjusted on VAT table in PLC program & PWM pulse output can be monitored during adjustment.
