(1) Output shutoff signal (MRS signal)
⋅
Turning on the output shutoff signal (MRS) during inverter running
shuts off the output immediately.
⋅
Terminal MRS may be used as described below.
(a) When mechanical brake (e.g. el
ectromagnetic brake) is used to
stop motor
The inverter output is shut off when the mechanical brake
operates.
(b) To provide interlock to disable operation by the inverter
With the MRS signal on, the inverter cannot be operated if the
start signal is entered into the inverter.
(c) Coast the motor to a stop.
When the start signal is turned off, the inverter decelerates the
motor to a stop in the preset deceleration time, but when the MRS
signal is turned on, the motor coasts to a stop.
(2) MRS signal logic inversion
(Pr. 17)
⋅
When
Pr. 17
is set to "2", the MRS signal (output stop) can be
changed to the normally closed (NC contact) input specification.
When the MRS signal turns on (opens), the inverter shuts off the
output.
REMARKS
⋅
The MRS signal is assigned to the terminal MRS in the initial setting. By setting "24" in any of
Pr. 178 to Pr. 189 (input terminal
function selection)
, the RT signal can be assigned to the other terminal.
⋅
The MRS signal can shut off the output, independently of the PU, external or network operation mode.
CAUTION
⋅
Changing the terminal assignment using
Pr. 178 to Pr. 189 (input terminal function selection)
may affect the other functions. Please
make setting after confirming the function of each terminal.

The above parameters can be set when
Pr. 160 User group read selection

(Refer to page 175)
(1) 2-wire type (STF, STR signal)
⋅
A two-wire type connection is shown below.
⋅
In the initial setting, the forward/reverse rotation signals (STF/STR) are used as start and stop signals. Turn on
either of the forward and reverse rotation signals to start
the motor in the corresponding direction. If both are turned
off (or on) during operation, the inverter decelerates to a stop.
⋅
The speed setting signal may either be given by entering
0 to 10VDC across the speed setting input terminal 2-5,
by setting the required values in
Pr. 4 to Pr. 6 Multi-speed setting (high, middle, low speeds)
, etc. (For multi-speed
operation, refer to
page 88
)
⋅
When
Pr. 250
is set in any of "1000 to 1100, 8888", the STF signal becomes a start command and the STR signal a
forward/reverse command.
You can select the operation of the start signal (STF/STR).
Used to select the stopping method (deceleration to a stop or coasting) when the start signal turns off.
Used to stop the motor with a mechanical brake, etc. together with switching off of the start signal.

⋅
A 3-wire type connection is shown below.

The start self-holding selection becomes valid when the STOP
signal is turned on. In this case, the forward/reverse
rotation signal functions only as a start signal.
⋅
If the start signal (STF or STR) is turned on and then of
f, the start signal is held and makes a start. When changing
the direction of rotation, turn STR (STF) on once and then off.
⋅
To stop the inverter, turning off the STOP signal once decelerates it to a stop.
