The features of the ST-MDC control
1. Simple wiring: input dc motor can run programmatically;
2. Periods of control program: it can realize continuous forward,continuous reverse, continuous positive & nagetive, Five period ofmovement control mode can be realized;
3. Upper machine communication, through RS232 serial portcommunication, realize the PC computer and control communications.It can be realize multistratum control and speed setting by changingthe machine's settings through the computer;
4. External control signal input and output; It can Support 3 signalinput, 3 Signal output: easy to accept external models of input andoutput, such as switches, optoelectronic switch, electromagnetic valveControl, etc;
5. Small size: small volume, only as big as the motor appearance, noneed complicated Electric control box, it can work by imput DC powersupply;
6. Embedded process: the process use ARM chip, can be embeddedsecondary development for users. Realize the user's different controlfunction without comprehensive html. Save the cost of softwaredevelopment;
7. Support external LCD screen: color screen can easily realizeexternal data show, making users' products more upscale.
8. Low cost: the product is the best in the same products. It simplify thecomplex design and programming so that greatly reduced cost.
