Terminal [Y1] to [Y4] Function
Terminal [Y5A/C] and [30A/B/C] Function (Relay output)
E20 through E24 and E27 assign output signals (listed on the next page) to general-purpose, programmable output terminals
[Y1], [Y2], [Y3], [Y4], [Y5A/C] and [30A/B/C].
These function codes can also switch the logic system between normal and negative to define how the inverter interprets the
ON or OFF state of each terminal. The factory default setting is normal logic system "Active ON."
Terminals [Y1], [Y2], [Y3] and [Y4] are transistor outputs and terminals [Y5A/C] and [30A/B/C] are relay contact outputs.
In normal logic, if an alarm occurs, the relay will be energized so that [30A] and [30C] will be closed, and [30B] and [30C]
opened. In negative logic, the relay will be deenergized so that [30A] and [30C] will be opened, and [30B] and [30C] closed.
This may be useful for the implementation of failsafe power systems.
• When a negative logic is employed, all output signals are active (e.g. an alarm would be recognized) while the
inverter is powered OFF. To avoid causing system malfunctions by this, interlock these signals to keep them ON
using an external power supply. Furthermore, the validity of these output signals is not guaranteed for
approximately 1.5 seconds (for 40 HP or below) or 3 seconds (for 50 HP or above) after power-ON, so introduce
such a mechanism that masks them during the transient period.
• 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 subjected 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-second 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
output signals assigned apply exclusively to the specific drive control, which is indicated by letters Y (Applicable) and N
(Not applicable) in the "Drive control" column of the table given below. (Refer to page 5-2.)
Explanations of each function are given in normal logic system "Active ON."
