Chap. 5 FUNCTION CODES
• Terminals [Y5A/C] and [30A/B/C] use mechanical contacts that cannot stand frequent ON/OFF switching.
Where frequent ON/OFF switching is anticipated (for example, limiting a current by using signals subjecte
d
to inverter output limit control such as switching to commercial power line or direct-on-line starting), use
transistor outputs [Y1], [Y2], [Y3] and [Y4] instead.
The service life of a relay is approximately 200,000 times if it is switched ON and OFF at one-secon
d
intervals.
The table below lists functions that can be assigned to terminals [Y1], [Y2], [Y3], [Y4], [Y5A/C], and [30A/B/C]. The
descriptions are, in principle, arranged in the numerical order of assigned data. However, highly relevant signals are
collectively described where one of them first appears. Refer to the function codes or signals in the "Related function
codes/signals (data)" column, if any.
The FRENIC-MEGA runs under V/f control, dynamic torque vector control, V/f control with speed sensor, dynamic
torque vector control with speed sensor, vector control without speed sensor, or vector control with speed sensor. Some
function codes apply exclusively to the specific drive control, which is indicated by letters Y (Applicable) and N (Not
applicable) in the "Drive control" column in the tables. (Refer to page 5-2.)
Explanations of each function are given in normal logic system "Active ON."
