Specification of high-performance vector convertor
Appendix C: Instructions of expansion card for common encoder
(Apply to all series machines)
I. Introduction
VFD is equipped with expansion card for common encoder (namely PG card). As an optional
accessory, it's necessary for closed-loop vector control of frequency convertor. Select corresponding
PG card as per output way of encoder, and the specific models are as follows:
Optional
accessories
VFD-PG1
VFD-PG2
VFD-PG3
II. Mechanical installation and functional descriptions of control terminals
1. Installation way, appearance, specification and signal definition of wiring terminal can respectively
refer to Figure 1 and Table 1 in Appendix C:
1)
Please assemble and disassemble PG card after complete outage of frequency convertor;
2)
Connect J3 on control panel with expansion card through 18pin FFC (ensure correct
installation and proper snap joint).
