How to clear trip
If the brushless amplifier should trip, eliminate the cause and use any of the procedures (1)
to (4) below for reset.
(1) Turn off power, and when power LED has gone out, turn on power again.
(2) Press the switch
and present trip state displayed.
(3) Input the trip reset signal.
(When
or
is chosen in “ 33
I
1/
I
2 function selection”, enter “
I
1” and “
I
2”
at the same time; when
or
is chosen, enter “
I
2” for trip reset.
If
is selected for “ 34
I
3 function selection”, “ 35
I
4 function selection”, “ 36
I
5
function selection”, trip reset can also be performed by inputting a signal.
Trip reset signal, when continued to be input, is designed to become ineffective in
order to prevent inadvertent restarting. Enter trip reset signal only when necessary.)
(4) Resetting trip with PANATERM for BL
Trip can be reset from the PC by using optional PC connection cable
*1
(option) and
communication software (PANATERM for BL: can be downloaded from our web site
free of charge).
For details, refer to PANATERM for BL instruction manual.
Note: When the cause is Overcurrent error
, Sensor error
, CPU error
or User parameter error
, turn off power as described (1) above.
Otherwise, the trip cannot be reset.
<Caution>
In clear trip, be sure to find and remove the trip factor before clear.
*1 To use the optional PC connection cable (sold separately), RS232 port is required.
When the PC has no RS232 port, use RS232-USB converter.
How to clear trip
If any trouble should be found, follow the steps below for check and countermeasure.
• If the cause cannot be found, it is recommended to use the Digital key pad, PANATERM
for BL, RS232 communication, and check the detail of trip. If failure is likely, or when
any part is damaged, or when you are in any other trouble, contact the sales agent of
purchase or our company.
Phenomenon
Detail of checking
Measure, etc
Motor does not
rotate.
Check for abnormality of wiring.
Apply proper wiring.
Check whether protective function
is activated. Check whether alarm
LED (red) is on.
Check the detail of trip .
Turn off power once, and turn on again.
Check whether power LED (green)
is lighted up.
Turn on power.
Check whether voltage on input
power is normal.
Check the supply voltage.
Check whether operation start
signal is input.
Check the condition of operation
instruction.
When driving with the RUN switch
on the front of the product, is the I1
input enabled switch (SW 3) on the
back of the product turned ON?
When operating with the RUN switch on
the front of the product, set SW3 to OFF.
Check whether analogue speed
instruction is set at 0 V.
Raise the analogue speed instruction little
by little.
Motor does not
rotate or stops
during operation.
Check whether protective function
is activated.
Overload is possible. Reduce the load or
increase the output capacity.
Motor stops
during
deceleration.
Check whether the inertia of load is
too large.
Regenerative voltage protection may have
worked. Decrease the inertia.
Turn off power once, and turn on again,
and reset the trip state.
Make deceleration time longer.
Alternatively, apply free-run stop.
Large vibration or
noise.
Output shaft of motor (gear head)
and shaft of load are not aligned.
Check the joint between the output shaft
and load shaft of the motor (gear head).
Motor and gear head are not
assembled correctly.
Check the assembling condition
between motor and gear head, and their
combination, and assemble them properly.
Damage to gear head or bearing.
