Note: 1. If the MRS signal is on, the operation mode cannot be switched to the PU
operation mode when the start signal (STF, STR) is on.
2. The operation mode switches to the external operation mode independently
of whether the start signal (STF, STR) is on or off.
Therefore, the motor is run in the external operation mode when the MRS
signal is switched off with either of STF and STR on.
3. When the protective function (major fault) is activated, the inverter can be
reset by pressing the
4. Switching the MRS signal on and rewriting the Pr. 79 value to other than "7"
in the PU operation mode causes the MRS signal to provide the ordinary
MRS function (output stop). Also as soon as "7" is set in Pr. 79, the
operation mode is switched to PU operation mode.
(3) Operation mode switching by external signal
1) Preparation
Set "8" (switching to other than external operation mode) in Pr. 79.
Use any of Pr. 180 to Pr. 183 (input terminal function selection) to set the terminal
used for X16 signal input.
Refer to page 148 for Pr. 180 to Pr. 183 (input terminal function selection).
Note: When terminal assignment is changed using Pr. 180 to Pr. 183, the other
functions may be affected.
Check the functions of the corresponding terminals before making settings.
2) Function
When the X16 signal is switched on in the PU operation mode, the operation mode
is forcibly changed to the external operation mode. When the X16 signal is switched
off in the external operation mode, the operation mode is changed to the PU
operation mode. When the X16 signal is switched off during network operation such
as computer link, the operation mode is changed to the PU operation mode as soon
as the switch-over command to the external operation mode is sent from the
computer. Note that this switch-over may only be made while the inverter is at a stop
and cannot be made during operation.
