Abstract
A servo driver includes: a driver, a pulse conversion module and a pulse interface. The pulse conversion module is connected between the pulse interface and the driver, and the pulse conversion module converts the type of a pulse control signal received by the pulse interface from an upper computer or a PLC and then outputs same to the driver. The type of the pulse control signal includes at least one of a clockwise and counter-clockwise pulse control type, a pulse plus direction control type and an AB-phase input control type. In an embodiment, the pulse conversion module is used to convert the type of the pulse control signal from the upper computer or the PLC, so that the driver can be compatible with an upper computer or a PLC having a different control signal type.
Claims13
A servo driver, comprising:
- a driver;
- a pulse interface;
- and
- a pulse conversion module connected between the pulse interface and the driver, the pulse conversion module configured to
- convert a type of a pulse control signal received by the pulse interface, the type of the pulse control signal including at least one of (i) a clockwise pulse control type and a counter-clockwise pulse control type, (ii) a pulse plus direction control type or (iii) an AB-phase input control type, and
- output the pulse control signal, once converted, to the driver;
- wherein the pulse conversion module includes a complex programmable logic device, which further includes a pulse conversion logic configured to realize pulse conversion between different pulse control signal types;
- wherein the pulse conversion module further includes a display and at least one button, the display and the at least one button being in signal communication with the complex programmable logic device;
