5.9.2 Function of Y Terminals
The drive provides a digital output (Y) terminal, an analog output (AO) terminal, a relay ter
-
minal and an Y4 terminal (either high-speed pulse output or open-collector output).
Extra AO terminal (AO2), relay terminal (relay2) and Y terminal (Y2) are provided by the I/O
extension card.

0: Pulse output (Y4P)
1: Digital output (Y4R)
This function parameter is a programmable multiplexing terminal and determines whether Y4
terminal is high-speed pulse output (Y4P) or open-collector output (Y4R). When used for high-
speed pulse output, max. output frequency is 100 kHz.

5
Zero-speed running
(no output at stop) When output frequency is 0 during drive running, terminal set for this
function becomes on. When the drive stops, terminal becomes off.
6
Motor overload
pending
The AC drive judges motor overload pre-warning according to pre-
warning threshold before performing overload protection. If this thres
-
hold is exceeded, terminal set for this function becomes on. For motor
overload parameters, see descriptions of “ F 9 - 0 0 ” to “ F 9 - 0 2 ” .

Length reached
Terminal set for this function becomes on when detected actual length
exceeds value set in FB-05.

12 Accumulative
running time
reached
Terminal set for this function becomes on when accumulative running
time of the AC drive exceeds value set in F8-17.
When the AC drive is running and has output frequency (can be zero),
terminal set for this function becomes on.
2
Fault output
When a fault occurs and the AC drive stops due to the fault, terminal
set for this function becomes on.
Terminal set for this function becomes on 10s before the AC drive
performs overload protection.
Terminal set for this function becomes on when count value reaches
the value set in FB-08.
Terminal set for this function becomes on when count value reaches
value set in FB-09.
Terminal set for this function outputs a pulse signal with width of
250 ms when simple PLC completes one cycle.
13 Frequency limited
Terminal set for this function becomes on when frequency reference
exceeds frequency upper or lower limit, and output frequency of the
AC drive also reaches the upper or lower limit.
