(6) Connect signal lines.
Connect connector 1CN as follows:
(1) Turn the power OFF.
(2) Retrun the alarm signal circuit shorted in
the above step (3) to its original state.
(3) Connect connector 1CN.
(4) Turn the power ON again.
(7) Check input signals.
Check the input signal wiring in monitor mode.
For the checking method, refer to 4.1.6 Opera-
tion in Monitor Mode.
• Checking method
Turn each connected signal line ON and
OFF to check that the monitor bit display
changes accordingly.
Input Signal
High level or open
0 V level
If the signal lines below are not wired correctly, the motor fails to rotate. Always wire
them correctly. (If signal lines are not to be used, short them as necessary.)
P-OT 1CN-16 Motor can rotate in forward direction when this input signal is at 0 V.
N-OT 1CN-17 Motor can reverse when this input signal is at 0 V.
S-ON 1CN-14 Servo is turned ON when this input signal is at 0 V. However, leave
the servo in OFF status.
(8) Turn servo (motor) ON.
Turn the servo ON as follows:
(1) Check that no reference has been input.
For speed/torque control (SGDA-
V-REF (1CN-3) and T-REF (1CN-1) are at 0 V.
For position control (SGDA-
PULS (1CN-1) and SIGN (1CN-3) are fixed.
