6.9.2 Function of DO Terminals
The drive provides a digital output (DO) terminal, an analog output (AO) terminal, a relay terminal
and an FM terminal (either high-speed pulse output or open-collector output).
Extra AO terminal (AO2), relay terminal (relay2) and DO terminal (DO2) are provided by the I/O
extension card.

This function parameter is a programmable multiplexing terminal and determines whether FM
terminal is high-speed pulse output (FMP) or open-collector output (FMR). When used for high-
speed pulse output, max. output frequency is 100 kHz. For details, see the description of

These ve function parameters select the function of the ve digital output terminals. T/A-T/B-T/
C is the relay of the drive and P/A-P/B-P/C is the relay on the I/O extension card.
The functions of the digital output terminals are described in the following gure.
Value Function Description
0 No output
Terminal has no function.
1 AC drive running
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.

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
threshold is exceeded, terminal set for this function becomes on. For
motor overload parameters, see descriptions of

7 AC drive overload
pending
Terminal set for this function becomes on 10s before the AC drive
performs overload protection.
8 Set count value

Terminal set for this function becomes on when count value reaches
the value set in Fb-08.
9 Designated count
value reached
Terminal set for this function becomes on when count value reaches
value set in Fb-09.
