manual energy saving operation, refer to Figure 4.3.88.
(22). PID integral reset (setting = 21).
(23). External fault (setting = 25)
. When an external fault occurs, the external fault input terminal is started, the
inverter will be turned off and the motor will coast to stop.
. If the external input terminal S3 is set (03-02 = 25) to the external fault, it will
display the message (EF3) "EF3 Ext. Fault (S3)"
. All eight input terminals (S1 to S8) can be designated as the external fault inputs.
(24). 3-wire sequence(forward / reverse command) (setting = 26).
. Refer to the 3-wire operation mode in Figure 4.3.2.
(25). Local / Remote selection (setting = 27).
. Users can switch the inverter frequency reference, input operation command
either in Local (via the digital operator) or Remote mode (via control circuit terminals
or RS485 online). You can use 00-05 (reference frequency) and 00-02 (operation
way) to determine the selection of input source.
. Local / Remote mode can be controlled by one of the multi-function digital input
terminals S3 to S8. one of parameters 03-02 to 03-07 is set to 27 (Local / Remote
control selection), 03-00 to 03-01, for 3-wire control, S1 & S2 are forced to set to
operation & stop input. Please refer to the following table.
Input
terminal
Mode Contents
ON Local mode
. Execute frequency command and operation command
through digital operator.
. Indicators of SEQ and REF are off.
OFF
Remote
mode
. Execute frequency command and operation command
through control terminal or RS-485 communication. It
might be achieved via 00-05(frequency command) and
00-02(operation command).
. Indicators of SEQ and REF are on.
. For switching Local/Remotemode，you have to stop the inverter firstly before execute
the switch.
(26). Remote mode selection (setting = 28).
. In Remote mode, indicators of SEQ and REF are on, you can use terminals AI1 and
AI2 to control the frequency command, and use terminals S1, S2 or communication
terminal RS-485 to control the operation command.
. By setting control terminals (S1 ~ S8) or communication RS-485, you can set one
parameter from 03-02 to 03-07 to 28 (operation selection of remote mode). Refer to
Figure 4.3.23.
