Vibration is occurring
at the same fre-
quency as the power
supply.
Inductive noise is occurring. Check to see if the drive control
signal lines are too long.
Shorten the control signal lines.
Check to see if the control sig-
nal lines and power supply
lines are bound together.
• Separate control signal lines
from power supply lines.
• Use a low-impedance power
supply for control signals.
The command
velocity or torque is
not reached.
The input command value
exceeds the velocity limit value
or the torque limit value.
Check to see if the Internal limit
active bit of Statusword is
active.
Input the command value that
does not exceed the velocity
limit value or the torque limit
value from the host controller.
