(4) Speed change/torque limit value change errors (300 to 399)
These are errors detected at speed change or torque limit value change.
The error codes, causes, processing and corrective actions are shown in Table
1.6 below.
The speed was changed for the axis during home
position return.
The speed after speed change is set outside the
range of 0 to speed limit value.
The absolute value of speed after speed change is
set outside the range of 0 to speed limit value.
The speed was changed during high-speed
oscillation.
The speed change to "0" was requested during
high-speed oscillation.
The value outside the range of 1 to 1000[%] was
set in the torque limit value change request
(CHGT).
The torque limit value change request (CHGT) was
made for the axis that had not been started.
