Technical Information and Features

Logical control of an Hitachi vfd SJ700D series application via the inverter-integrated programming function

Complex logic sequences are programmed using EzSQ and then downloaded to the SJ700 inverter. External logic using a PLC or relays can be avoided.

- Basic-like high level language
- Max. 512 Steps
- Position Control (with encoder)

Examples of use include automatic speed control based on load, such as the swift-lift function of a crane. Other examples include: Sleep Mode, load distribution and many more.
