1. terminals U, V, and W on
the motor are wrongly
connected
2. the encoder is wrongly wired
Check the wiring

The maximumly-permitted
following error is too small
Set a wider value range
for the detection of
following error (P34)
The position loop gain is too
small
Give more gains
No enough torque Check the limit value of
current
Reduce the load
Use a drive and motor
with bigger power
Low speed Check the maximum
speed limitation (refer to
parameter P26)
Command pulse frequency is
too high
1. Lower the frequency
2. Check whether P36
has the right value
