VFD-F Series
DELTA ELECTRONICS, INC. ALL RIGHTS RESERVED
5-17
External relay specifications = 8A/250VAC or 5A/30VDC.
Relay delay time is 5~10 msec.
03 - 08 Master Frequency Attained 1
Factory Setting: 0.00
03 - 09 Master Frequency Attained 2
Settings 0.00~120.00 Hz Unit: 0.01
An output relay may be programmed to activate when the output frequency exceeds the
desired attained frequency setting of these two parameters.
There is a
±
2Hz window of operation. If the master frequency attained is 20Hz and the
output frequency exceeds 20Hz, the corresponding output relay will be “closed”. When the
output frequency is less than 18Hz, the corresponding output relay will be “opened” as the
following diagram shows.
