Motor-free
When preset signal is turned on, the motor is free to rotate. If the
motor-free signal is turned on during motor operation, the load may
keep moving through inertia and hit mechanical stops. In addition, it
is impossible to give run command to the motor with motor-free sig-
nal turned on. Be sure to turn off the signal in running. In switching
the motor-free signal from on to off, input the run start signal after
100ms or longer the motor-free signal is turned off.
In the case where relative travel command is used for positioning
operation, if positioning operation is executed after turning on and
then off the motor-free signal, positioning might shift. If this is incon-
venient to your application, set Pr49 to "1. homing operation is re-
quired again when motor is free". Then, homing operation is re-
quired again for executing positioning operation when motor-free
condition (or trip) is cleared.
･
When more than one signal input is assigned to the same function, the signal is made effective when any one
signal is input.
･
Logic of signal input can be changed by setting the polarity change parameter (Pr54 – 57,72,73) (Set an input
desired to be operated on disconnected side of wiring such as 0: Normal logic (Input is effective in connecting
with GND), 1: Inverted logic (Input is effective by OPEN), Inverted logic is forced trip (emergency stop input ).
･
Parameters above (Pr54 – 57,72,73) are made effective after power is turned on again.
8-2-2 Signal output selection function
Function can be assigned to signal output 01 and 02 by Pr5C and 5d

Description of function (standard logic)
０
Trip output
This signal is normally on, and turns off when tripping occurs.
１
In-position
This signal turns on when motion command is completed as well as position
error is within Pr38.
２
In-motion (BUSY)
This signal turns on during run command.
(Run start signal is not accepted as long as this signal is on.)
３
Homing completion
This signal turns on when homing operation is completed.
４
Overload detection
This signal turns on when torque reference above 100 is output.
５
Torque under restriction
This signal turns on as long as torque is restricted.
・
Logic of signal output can be inverted by polarity choosing parameter (Pr5E and 5F).
