About this manual
The CD75-750 User's Guide provides safety instructions, installation requirements, and operating information for the variable‑speed drive used with standard AC induction motors from 0.75 kW to 7.5 kW. It emphasizes qualified installation, proper grounding, and the use of protective components such as varistors and RFI filters.
The manual also details the drive’s parameter settings, including preset ramp selectors, load‑output configuration, and serial‑communication broadcast mode, as well as guidelines for power‑supply configurations and motor thermistor protection.

Frequently asked questions
What safety precautions must be taken when installing the CD75-750?
Only qualified personnel should install the drive, the PE connection must always be grounded, and a varistor should be used when the line‑to‑ground voltage may exceed 320 Vac.
How do you enable broadcast mode on the serial communications network?
Set the communication address to 0; this reserves address 0 for broadcast mode, causing all drives to respond simultaneously.
What does parameter b24 control?
Parameter b24 selects the load output; when set to 1, terminal 19 becomes a digital load‑reached output that changes state when the drive load reaches a set value.
