Motor Does Not Run
Causes
Check that the present
control mode is correct
with monitor mode of the
front panel.
Check that the external
analog input (N-ATL/
P-ATL) is not used for the
torque limit.
Check that the motor
moves by expected
revolution against the
command pulses.
In the front panel monitor
mode, is the Pin No.
corresponding to SRV-
ON in " - " state?
In the front panel monitor
mode, is the Pin No.
corresponding to NOT/
POT in " A " state?
Check that the input
pulse counts and
variation of command
pulse sum does not slips,
with monitor mode of the
front panel.

Measures
1) Set up Pr0.01 again.
2) Check that the input to control mode switching
(C-MODE) of the Cnnector X4 is correct, when
Pr0.01 is set to 3 to 5.
1) Set up Pr05.21 to 0 and apply -9 [V] to N-ATL and
+9 [V ] to P-ATL when you use the external input.
2) Set up Pr05.21 to 1 and set up the max. value to
Pr0.13 when you use the parameter value.
1) Check the setups of Pr0.09, Pr0.01 and Pr5.00 to
Pr5.02 again.
2) Connect the electronic gear switching input (DIV) of
Connector X4 to COM–, or invalidate the division/
multiplication switching by setting up the same
value to Pr0.09 and Pr5.00.
Check and make a wiring so as to connect the SRV-
ON input to COM–.
1) Check and make a wiring so as to connect both
NOT/POT inputs to COM–.
2) Set up Pr5.04 to 1 (invalid) and reset the power.
1) Check that the command pulses are entered
correctly to the direction selected with Pr0.05.
2) Check that the command pulses are entered
correctly in the format selected with Pr0.07.
1) Check and make a wiring so as to connect the INH
input to COM–.
2) Set up Pr5.18 to 1 (invalid).
1) Check and make wiring so as to open the CL input
2) Set up Pr5.17 to 2 (invalid).
