SSA 1 : System alarm in the spindle amplifier
(The above are errors related to the third/fourth serial spindle. They are
reflected in spindle alarm 749. They are usually caused by noise,
disconnection, or instantaneous power interruption.
When these statuses appear under diagnosis number 438, check whether
there is a problem with the hardware related to the serial spindle connector
panel or the cables and spindle amplifier connected to the panel.

To display the load and speed meter readings, the following parameters
must be specified:
Maximum motor speed: Set for each axis in parameter Nos. 4020 (main)
and 4196 (sub)
Load meter reading at maximum output: Set for each axis in parameter
Nos. 4127 (main) and 4276 (sub)
NOTE
The spindle switch function is used for main/sub switching.
Select main spindle when the spindle switch function is not
being used.
