Inspecting Connection And Status Of Input Signal Circuits - YASKAWA SGMJV User Manual

4.3.1 Inspecting Connection and Status of Input Signal Circuits

Check the items in step 1 before trial operation of the servomotor under speed control and position control ref-
erences from the host.
Check the connection and status of input signals using the following procedure.
Step
Connect the necessary input signal circuits to the I/O signal connector (CN1) under
the following conditions.
• It must be possible to input servo ON input signal (/S-ON).
• The forward run prohibited (P-OT) and reverse run prohibited (N-OT) input sig-
nals must be ON (L level) (i.e., the servomotor must be able to run in forward and
reverse).
Settings: CN1-42 and CN1-43 must be ON (L level) or Pn50A.3 and Pn50B.0
must be set to 8.
Note: Return the settings to the previous ones after completing trial operation.
• Make sure that there is no reference input.

incremental encoder, which makes it possible to perform trial operation of the ser-
vomotor without Fn008 and SEN signal settings
Connect a safety device to CN8 when using the safety function.
For the connecting method, refer to (1) Connecting a Safety Device.
2
Connect the connector of the host and the I/O signal connector (CN1) together.
Turn ON the power and make sure that the panel operator display is as shown below.
Check the input signal using the Un005 (input signal monitor) from the panel opera-
tor. If the display is not same as shown below, correct the input signal setting.

Note:
• If an absolute encoder is being used, turn ON the SEN signal. The servo will not
turn ON when only servo ON signal (/S-ON) is input.
• When the SEN signal is checked in monitor mode, the top of the LED will light
because the SEN signal is high when ON.
• Input signals can be also checked using wiring check function of SigmaWin+.
