frequency too high
causes
communication alarm.
One of the phases R, S, and
T is lost.
The fan built in the servo
stops running.
The external regenerative
brake resistor is connected
fault improperly or disconnected.
There is a phase loss in
safety terminal input.
Safety terminal input 1 is
abnormal.
Safety terminal input 2 is
abnormal.
1. The DSP CPU utilization is
too high.
2. The DSP has bugs.
Two or more digital inputs
are configured with the same
function.
When
standard, analog input 3 is

The pulse input frequency
detected by the drive is
higher than the specified
frequency.
1. External input pulse signal
frequency is too high.
Possible cause

Workaround
2. Route communication cables
and motor cables separately.
1. Ensure power wiring is proper.
2. Set P0.12 correctly.
Check whether there is a foreign
material. If the alarm persists after
the foreign material is found and
removed, replace the drive.
1. Check the connections B2 and
B3 when the regenerative brake
resistor is built in.
2. Ensure the
regenerative brake resistor is
connected properly.
Ensure the safety terminal input
wiring is proper.
Ensure the safety terminal input
wiring is proper.
Ensure the safety terminal input
wiring is proper.
1. Disable unnecessary functions.
2. Contact the customer service
personnel to update the DSP.
Set P3.00–P3.07 and ensure
each setting is unique.
a
Set P3.70 correctly.
1. Reduce the external input
pulse signal frequency.
2. If the fault persists though the
external input signal is normal,
replace the drive.
