5 Connect a check board to observe torque differences.
If an analog check board is used, set the rotary switch of the check
board to 1, and observe signals on CH7.
If the oscilloscope is a combined analog/digital model, set the DATA
digit for CH1 to 5, and observe signals on CH1.
6 Convert the observed value, using the formula 1 V = 410 (specified
threshold value). Read the maximum value during ordinary operation,
and allow an appropriate margin.

Value in parameter No. 8317 (if only one master/slave axis
pair is in sync) or 8327 (if more than one master/slave axis
pair is in sync), or 512 ms (if neither parameter is set).
If the servo preparation completed signal SA <F000#6> is 0, torque
difference alarm detection is not performed.
The simple synchronous control functions are described separately for the
T series and M series in the following explanations.
[Classification] Input signal
[Function] synchronous control is performed for memory or MDI operation.
The signal is provided for each controlled axis. The number at the end
of the signal name represents the number of the controlled axis.
1. ... The first axis becomes the slave axis for synchronous control.
2. ... The second axis becomes the slave axis for synchronous control.
3. ... The third axis becomes the slave axis for synchronous control.

[Operation] When the signal is set to 1, the control unit operates as described below:
– During memory or MDI operation, the control unit supplies the move
command, specified for the master axis, to both the master and slave
axes of synchronous control.
The master axis is specified with a parameter.
